#Data Grid

WYSIWYG and Data-Aware Export Enhancements

We added a new PrintExportCompleted event to all View types. Handle this event to determine whether view data was printed or exported without errors. Use the e.Status event parameter to determine if the operation was successful, failed, or was cancelled.

                    using DevExpress.XtraEditors;
                    using DevExpress.XtraGrid.Views.Base;

                    public Form1() {
                        InitializeComponent();
                        gridView1.PrintExportCompleted += GridView1_PrintExportCompleted;
                    }
                    private void GridView1_PrintExportCompleted(object sender, PrintExportCompletedEventArgs e) {
                        if(e.Status == GridPrintExportResult.Error)
                            XtraMessageBox.Show(
                                new XtraMessageBoxArgs() {
                                    Text = "An unexpected error occurred while exporting data.",
                                    Caption = "Error",
                                    ImageOptions = new MessageBoxImageOptions() {
                                        SvgImage = svgImageCollection1[0],
                                        SvgImageSize = new Size(32, 32)
                                    }
                                });
                    }

#Data Editors

Lookup Editor – Multiple Item Selection

Our WinForms Lookup Editor includes a new multiple item selection option. With this capability, you can display a checkbox column within the lookup and allow users to select multiple values using the mouse or keyboard.

Documentation

Color Editors - Allow Null Input

Our WinForms ColorEdit and ColorPickEdit controls now set the EditValue property to null (Nothing in Visual Basic) if the AllowNullInput option is enabled and a user presses Ctrl+Del or Ctrl+0.

We added a new NullColor property so you can specify a custom null color. This value is assigned to the editor's Color property when the user resets the edit value.

#Skins and Vector Icons

Support for Default App Mode in Windows OS

We added a new WindowsFormsSettings.TrackWindowsAppMode setting. When enabled, your application can track the Default App Mode setting used in Windows OS and only display light or dark color palettes within the Skin gallery.

Available for the DevExpress "WXI", "Basic", and "Bezier" skins.

                    static void Main() {
                        Application.EnableVisualStyles();
                        Application.SetCompatibleTextRenderingDefault(false);
                        WindowsFormsSettings.TrackWindowsAppMode = DevExpress.Utils.DefaultBoolean.True;
                        Application.Run(new Form1());
                    }

Documentation

System and Custom Accent Colors

DevExpress vector skins can now change associated colors once end users make a change to a system accent color within Microsoft Windows. Activate the WindowsFormsSettings.TrackWindowsAccentColor setting to enable this option*.

                        using DevExpress.Utils;
                        using DevExpress.XtraEditors;

                        static void Main() {
                            Application.EnableVisualStyles();
                            Application.SetCompatibleTextRenderingDefault(false);
                            WindowsFormsSettings.TrackWindowsAccentColor = DefaultBoolean.True;
                            Application.Run(new Form1());
                        }

You can also specify a custom accent color and apply the desired appearance on the fly.

                    DevExpress.XtraEditors.WindowsFormsSettings.SetAccentColor(Color.FromArgb(16,124,65));

"The Bezier" skin supports a secondary accent color. Use the WindowsFormsSettings.SetAccentColor2 method to specify a second accent color.

* The WindowsFormsSettings.TrackWindowsAccentColor setting does not work with our High Contrast skin.

Documentation

WXI Skin - Enhanced Rendering

We enhanced the rendering of our text input and dropdown editors with a custom background color (WXI skin*).

* Our WinForms BreadCrumbEdit, MemoEdit, and TokenEdit controls do not support this feature.

#Charting

Enhanced Visualization of Spline Series

We enhanced the visualization of our spline chart - the spline line is rendered between local minimum and maximum values:

Use the SplineAlgorithm property to specify the drawing algorithm used for the Spline series view.

This change affects the following series views:

• SplineSeriesView
• SplineAreaSeriesView
• StackedSplineAreaSeriesView
• FullStackedSplineAreaSeriesView
• Spline3DSeriesView
• SplineArea3DSeriesView
• StackedSplineArea3DSeriesView
• FullStackedSplineArea3DSeriesView

Read the following breaking change advisory for detailed information: The default drawing algorithm of Spline series view was changed

#Dialogs

Preview Pane

Our WinForms Open File and Save File Dialogs ship with an integrated Preview Pane. Your users can now preview PDFs, Office-related documents, HTML file, text files, and images within the dialog.

Customize Context Menu

We added new events designed to customize context menus (add new commands, hide/disable commands, etc.) in our WinForms File Explorer Assistant component:

• ContextMenuShowing
• BeforeExecuteItemCommand

                    assistant.Attach(grid, x => {
                        x.CurrentPath = initialPath;
                        string customCommandName = "custom";
                        x.ContextMenuShowing += (s, e) => {
                            e.MenuItems.AddCommand("Custom command", customCommandName);
                        };

                        x.BeforeExecuteItemCommand += (s, e) => {
                            if(e.CommandName == customCommandName) {
                                XtraMessageBox.Show("Custom command executed");
                                e.Cancel = true;
                            }
                        };
                    });

#Filtering UI

Filter Control - UX Enhancements

The WinForms Filter control includes a new ShowActionButtonMode property that specifies whether the Filter Control always displays action buttons (for example, add or remove a condition) or displays buttons on hover.

                    filterControl1.ShowActionButtonMode = DevExpress.XtraEditors.ShowActionButtonMode.Always;

#Gantt Control

Timeline

The WinForms Gantt control includes a new integrated Timeline.

Features include:

#HTML & CSS Support

Reusable HTML & CSS Templates

Our WinForms HTML & CSS Template Gallery includes a set of predesigned templates based on those used in our WinForms demo applications. You can use these templates "as-is" or customize as needed. You can create an HTML & CSS template, save the template to the gallery, and use it in any WinForms project when needed.

Bind Image Tags to Data Fields with Image Names

You can now bind image tags to data source fields with image names. An HTML Template checks whether the data field contains SVG or bitmaps. If it does not, the template looks for an image with the specified name in the SvgImageCollection (assigned to the control's HtmlImages property).

                        <img class="icon" src="${IconName}"/>

#Ribbon

New Office 365 Style

Our WinForms Ribbon Control ships with a new Office 365 rendering style.

When our new Office 365 style is used, the WinForms Ribbon control displays a Search box at the top of the Ribbon form and displays Show Ribbon options on the bottom right of the Ribbon UI.

Use the following API to enable new UI enhancements in other Ribbon styles:

• RibbonControl.OptionsExpandCollapseMenu - Gets availability and behavior settings for the "Show Ribbon" popup menu.
• RibbonControl.ExpandCollapseMenuShowing - Allows you to customize the "Show Ribbon" menu or prevent it from being displayed (based on a specific condition).
• RibbonControl.SearchItemPosition - Specifies the position of the Search box.

Backstage View – Align Items to Top and Bottom

Backstage View item settings now include a new Alignment option. This option allows you to align items to the top and bottom of the Backstage View, and to the left and right of the Caption Bar and Quick Access Toolbar (when it is displayed below the Ribbon control).

backstageViewItem.Alignment = BackstageViewItemAlignment.Bottom;

Show Alerts within the Ribbon Message Bar

We implemented new APIs to display Office-inspired flyout notifications and alerts.

New APIs include:

• RibbonControl.ShowMessage - Displays a message in the message bar.
• RibbonControl.CloseMessage - Closes the specified message.
• RibbonControl.MessageClosed - Occurs after a message is closed and allows you to handle button clicks.
• RibbonControl.Messages - Gets a collection of messages displayed in the message bar.

                        using DevExpress.XtraBars.Ribbon;

                        void ShowMessage() {
                            RibbonMessageArgs args = new RibbonMessageArgs();
                            args.Caption = "What's New";
                            args.Text = "Explore new WinForms-related features we expect to introduce in our first major update this year (v23.1).";
                            args.Icon = MessageBoxIcon.Information;
                            args.Buttons = new DialogResult[] { DialogResult.OK };
                            args.Showing += Args_Showing;
                            Ribbon.ShowMessage(args);
                            Ribbon.MessageClosed += Ribbon_MessageClosed;
                        }
                        void Ribbon_MessageClosed(object sender, RibbonMessageClosedArgs e) {
                            if(e.Result == DialogResult.OK)
                                Data.Utils.SafeProcess.Start("https://community.devexpress.com/blogs/winforms/archive/2023/02/16/devexpress-winforms-roadmap-23-1.aspx");
                        }
                        void Args_Showing(object sender, RibbonMessageShowingArgs e) {
                            e.Buttons[DialogResult.OK].Caption = "Explore Roadmap";
                        }

Page Header Items – Colorization in Vector Skins

Page header items (BarButtonItem and BarCheckitem) can adjust text and SVG icon colors based on the background color in vector skins. The background color must be set to a Skin Color (at design time, switch to the "DX Skins" tab to choose a Skin Color).

#Rich Text Editor

Rotated Text in Tables

The WinForms Rich Text Editor now supports rotated text in table cells. We added a 'Text Direction' command to the Ribbon UI and a TableCell.TextDirection property to rotate cell text in code.

You can print and export (PDF) documents with rotated text in tables.

Documentation

Embedded Fonts

Our new API (Document.EmbedFonts API) allows you to embed fonts within Microsoft Word documents. Once fonts are embedded in a document, document appearance remains unchanged when viewed, printed, or exported on any computer (regardless of the presence of the font on the target machine). Embedded fonts are available within the font list.

Documentation

#Scheduler

Synchronize Appointments with Microsoft 365 Calendars

Our WinForms Scheduler control exposes new APIs and allows you to seamlessly synchronize user appointments with Microsoft 365 calendars (bi-directionally).

You can export appointments from the Scheduler control to Microsoft 365 calendars, import Microsoft 365 (Outlook) events to the Scheduler control, merge user appointments with Microsoft 365 calendars, and resolve merge conflicts.

Use Cell Values as Data Labels in Charts

You can now use cell values as data labels for a chart. Use the CustomDataLabels.SetReference method to specify a cell range used as a reference.

                    chart.Series[0].UseCustomDataLabels = true;
                    var customDataLabels = chart.Series[0].CustomDataLabels;
                    customDataLabels.SetReference("C2:C4");

You can print and export to PDF spreadsheet documents that contain charts with custom data labels.

Documentation

#TreeList

HTML & CSS Templates

Our WinForms TreeList Control now supports HTML & CSS Template engine. HTML & CSS Templates allow you to create unique layouts for TreeList nodes and the TreeList itself when empty.

New API includes:

• TreeList.HtmlTemplates - A collection of HTML-CSS templates that can be applied to TreeList UI elements.
• TreeList.NodeHtmlTemplate - Specifies the default HTML-CSS template used for nodes.
• TreeList.EmptyTreeHtmlTemplate - Specifies the default HTML-CSS template used for a TreeList control when empty.
• TreeList.QueryNodeTemplate - Allows you to assign HTML-CSS templates to nodes based on a specific condition.
• TreeList.QueryEmptyTreeTemplate - Allows you to assign HTML-CSS templates to an empty TreeList based on a specific condition.
• TreeList.CustomizeNodeTemplate - Allows you to customize "templated" nodes.
• TreeList.OptionsHtmlTemplates - Contains options that are applied when you use HTML-CSS Templates to render nodes.

Improved Performance for Large Hierarchical Binding Lists

We optimized our WinForms TreeList control to better address important usage scenarios. We enhanced the speed and efficiency when deleting nodes and updating child collections whenever the TreeList is bound to a very large hierarchical binding list. The TreeList now performs these operations up to 20 times faster.

#Accessibility and UI Automation

Scheduler Accessibility

We supported assistive tools and UI Automation patterns in our WinForms Scheduler control. The Scheduler control implements standard API used by accessibility client applications. All UI elements are labeled and properly recognized, property values are exposed, and appropriate events are raised.

Enable the WindowsFormsSettings.UseUIAutomation setting to use UI Automation patterns.

#UI Templates (EAP)

DevExpress UI Templates were designed to jump start the form design/development process. With this product, you can create/deliver ready-to-use UI solutions and address a variety of line-of-business (LOB) requirements in a timely manner (and eliminate the need for routine UI customizations when using DevExpress WinForms controls).

In v23.1, we added a new Twin Button template and extended our grid-based templates with new Contact and Task List templates. Active Universal, DXperience, and WinForms subscribers can download these templates as VSIX via the DevExpress Download Manager.

After you install our UI Templates, be sure to review our Quick Start Guide for technical guidance and watch our tutorial videos:

• Introduction to WinForms UI Templates
• How to Customize UI Templates

WPF Controls v23.1

#Startup & Memory Optimization

Themes

We optimized our existing application themes for better performance and less memory consumption. Themes now load fewer XAML resources, which reduces memory consumption by 15-30% and speeds up application startup by 10%.

New Lightweight Themes (CTP)

New themes include:

• Win10 (Light, Dark, System, System Colors)
• Office2019 (Colorful, Black, High Contrast, System)
• VS2019 (Blue, Light, Dark, System)

New themes are optimized for speed and memory consumption (they require/load less resources than existing themes). Performance enhancements include:

• Startup: 20-40%
• Switch between Views: 10-25%
• Memory Footprint: 40-50%

Documentation

Our lightweight themes require much less hard drive space. For example, DevExpress.Xpf.ThemesLW assembly with 12 theme variations is approximately 10MB compared to the 72MB required for a similar set of our existing (regular) themes.

We plan to optimize our lightweight themes in our second major release this year even further (theme key structure is subject to change). In v23.1, we ship new themes as CTP (Community Technology Preview). Please note that our further optimizations may affect theme resources overridden in your application.

Dialogs

We optimized our Open File, Save File, and Folder Browser dialog components for faster startup and less memory consuption.

The following internal test results help illustrate the performance advantages of this release:

#New Step Progress Bar

The WPF Step Progress Bar visualizes a linear process and highlights its active stage. It includes numerous UI/UX options to help you visualize event chains with ease. Features include:

Documentation

#Data Grid

Search/Filter within Column Headers

The Data Grid's column headers can now display search/filter boxes. Users can click a search icon and enter filter criteria within column headers.

Display the Automatic Filter Row and set the AutoFilterRowPosition property to 'Header' to activate this option.

Search in Master-Detail Mode

We introduced a new search option in our WPF Data Grid. Users can search data in expanded detail rows by entering a search expression within the grid's Search Panel.

Enable the detail view's SearchPanelHighlightResults or SearchPanelAllowFilter option to search within its expanded detail rows.

Documentation

Hide Bands from the Column/Band Chooser

Data Grid bands include a new ShowInColumnChooser option. Activate this option for the band if you do not want to display in the Column/Band Chooser.

Clear Filter Button in Auto-Filter Row

We added a new TableView.AutoFilterRowClearButtonMode property that allows you to display the Clear Filter button within Automatic Filter Row cells. Display option include: Always, Display, Edit, Never.

#Charting

Enhanced Visualization of Spline Series

We enhanced the visualization of our spline chart - the spline line is rendered between local minimum and maximum values:

Use the SplineAlgorithm property to specify the drawing algorithm for the Spline series view.

This change affects the following series views:

• SplineSeries2D
• SplineAreaSeries2D
• SplineAreaStackedSeries2D
• SplineAreaFullStackedSeries2D

Read the following breaking change advisory for detailed information: The default drawing algorithm of Spline series view was changed

#Data Editors

DateNavigator - Date Range Selection

The WPF Date Navigator fully supports multiple date selection. Use the DateNavigator.SelectionMode property to allow users to select a date range.

Tri-State Checkbox Cycle Order

#Property Grid

XAML Instance Initializer

You can now define custom data types for collections in XAML (you do not need to implement the IInstanceInitializer interface).

                        <dxprg:PropertyGridControl">
                            <dxprg:CollectionDefinition Path="Cars">
                                <dxprg:CollectionDefinition.NewItemInitializer>
                                    <dxprg:XamlInitializer Initialize="XamlInitializer_Initialize">
                                        <dxprg:TypeDefinition Name="Electric Car" Type="{x:Type local:ElectircCar}"/>
                                        <dxprg:TypeDefinition Name="Sport Car" Type="{x:Type local:SportCar}"/>
                                        <dxprg:TypeDefinition Name="Truck" Type="{x:Type local:Truck}"/>
                                    </dxprg:XamlInitializer>
                                </dxprg:CollectionDefinition.NewItemInitializer>
                            </dxprg:CollectionDefinition>
                        </dxprg:PropertyGridControl>

We added a new XamlInitializer.Initialize event that allows you to implement custom initialization of collection properties.

Keyboard navigation is currently available as a Community Tech Preview (CTP). Use the KeyboardNavigationEnabled option to enable keyboard navigation in our Blazor Grid.

Auto-Generated Cell Editors

Our Blazor Grid can now automatically generate pre-configured column cell editors based on the type of data they display (including the Filter Row). Use the EditSettings object to customize a column’s editor.

                        <DxGridDataColumn FieldName="Price">
                            <EditSettings>
                                <DxMaskedInputSettings Mask="@NumericMask.Currency" />
                            </EditSettings>
                        </DxGridDataColumn>

Use our new GetEditor method to place pre-configured cell editors into the Edit Form template.

                            <Columns>
                                <DxGridDataColumn FieldName="CategoryId" Caption="Category">
                                    <EditSettings>
                                        <DxComboBoxSettings Data="Categories" ValueFieldName="Id" TextFieldName="Name" />
                                    </EditSettings>
                                </DxGridDataColumn>
                            </Columns>
                        </DxGrid>

Checkbox Column

Our Blazor Grid now displays checkboxes (instead of text strings) in columns with Boolean values.

Use the DxCheckBoxSettings.ShowCheckBoxInDisplayMode property to specify whether to use checkboxes or strings to represent Boolean values. The following properties define custom strings:

• DxCheckBoxSettings.CheckedDisplayText
• DxCheckBoxSettings.UncheckedDisplayText
• DxCheckBoxSettings.IndeterminateDisplayText

Fixed (Pinned) Columns

Use our new FixedPosition property to anchor columns to the left or right side of the Grid. Fixed columns always remain visible when a user scrolls the Grid horizontally.

Just like regular columns, users can resize, show, and hide fixed columns. Users can also reorder columns pinned to the same side of the Grid.

.NET Reporting v23.1

#Reporting — All Platforms

Barcodes — Functional Control (FNC) Symbols Support

The Code-128 Barcode now supports FNC1-4 symbols. FNC (Functional Control) symbols provide additional information to the scanner. Use the following properties to specify symbols (or set of symbols) in barcode text:

• FNC1Substitute
• FNC2Substitute
• FNC3Substitute

Documentation

Chart Localization

The Localization Editor in Report Designer components allows you to localize the following chart elements/properties:

• Titles (legend, pane, series, constant line)
• Small Chart Text
• Empty Chart Text
• Text Annotations
• Legend Text (strip, constant line, indicator)
• Series Legend Text Pattern
• Strip Axis Label Text
• Custom Legend Item Text

Click the Property column header to modify a filter and select chart properties (Documentation: Localize Reports).

Online Demo

Chart Bindable Properties

Users can now use expression bindings to set up constant line values, strip axis values, chart titles, and other UI elements with ease. This enhancement reduces the amount of code required to customize the chart and streamlines the reporting process.

Documentation

Carried Forward/Brought Forward Totals

You can now calculate carried forward and brought forward totals (useful in accounting). Place XRLabel controls in the repetitive report bands (for example, group header and group footer with the RepeatEveryPage option enabled) and set the Summary property to CarryoverSum.

SqlDataSource — Configure Session

You can set up the SQL connection session before querying the database:

• Set the transaction isolation level for the SqlDataSource using the ConnectionOptions.IsolationLevel property (use the SqlQuery.IsolationLevel property for a SQL query).
• Implement IDBCommandInterceptor or IDBConnectionInterceptor to enable interception, modification, and/or suppression of MS SQL operations. This includes low-level database operations such as executing a command or setting a key-value pair in a session context. You can store the value in the session context and execute any request after the connection is opened.

Font Substitution for PDF Export Engine

Our PDF export engine now supports font substitution. If a font used in a report does not contain a glyph for a character, the PDF export engine uses a glyph from a fallback font (to display the character in the exported PDF file). The engine first looks for fonts specifically designed to be used as fallbacks. If fallback fonts are not available, the engine looks for fonts that are similar to the source font. As you would expect, end users will not lose text data when exporting reports to PDF, even when a font is not installed on the target machine.

Word Export (DOCX) — HTML-inspired Text Formatting Support

Our XRLabel controls or XRCrossTab cells with HTML content (AllowMarkupText) now exports to DOCX as text (in previous versions we exported HTML content as an image). This enhancement allows users to edit labels and cell content in a document after export.

                            private readonly IServiceScope scope;
                            public CustomEFContextProvider(IServiceScope scope) {
                                this.scope = scope;
                            }

                            public object GetContext(string connectionName, Type contextType) {
                                if(connectionName == "efCoreConnection")
                                    return scope.ServiceProvider.GetService(contextType);
                                return null;
                            }

                            public void Dispose() {
                                scope.Dispose();
                            }
                        }

Use the ConfigureServices() method of the "Startup" class to register the factory implementation.

                        services.ConfigureReportingServices(configurator => {
                            configurator.ConfigureWebDocumentViewer(viewerConfigurator => {
                                viewerConfigurator.RegisterEFContextProviderFactory<CustomEFContextProviderFactory>();

We changed the default zoom level. It is now Whole Page.

Online Demo

Blazor Report Viewer — Support for WebAssembly, Ahead-Of-Time (AOT) Compilation, and .NET MAUI Blazor

Our Native Blazor Report Viewer component supports the Blazor WebAssembly (WASM) hosting model and ahead-of-time (AOT) compilation. You can now preview, print, and export reports in your browser (with no need for an ASP.NET Core backend).

We also extended our Project Templates with a WebAssembly Reporting Application option.

You can leverage the capabilities of our Native Blazor Report Viewer component within .NET MAUI apps by hosting the component within the BlazorWebView.

Getting Started

#Reporting for .NET MAUI

You can now use DevExpress Reporting tools in your .NET MAUI apps for iOS and Android (to generate and export reports).

Documentation

#Reporting for Web

Web Report Designer — Backend-only Registration of Custom Report Controls and Custom Expression Functions

It now requires fewer steps to incorporate custom report controls and custom expression functions in web apps with report design capabilities.

To register a custom report control in the DevExpress Web Report Designer, you simply need to pass an instance of a report control to the designer's CustomControls collection at runtime. The component will then gather and transfer the required metadata to the client automatically (the report control will be available for the document generation engine and will appear in the Web Report Designer's toolbox).

                        @{
                            var designerRender = Html.DevExpress().ReportDesigner("reportDesigner")
                                .Height("100%")
                                .CustomControls(typeof(MyControl))
                                .Bind("TestReport");
                            @designerRender.RenderHtml()
                        }

Call the CustomFunctions.Register) method at application startup to register a custom expression function:

                        var builder = WebApplication.CreateBuilder(args);
                        // ...
                        DevExpress.XtraReports.Expressions.CustomFunctions.Register(new MyCustomFunction());
                        // ...
                        app.Run();

Use the static CriteriaOperator.RegisterCustomAggregate method to register a custom aggregate:

                        CriteriaOperator.RegisterCustomAggregate(new MyCustomAggregate());

These method calls collect function metadata and pass it to the client. The function becomes available in the Expression Editor.

Documentation: Custom Report Controls    Documentation: Custom Functions

Web Report Viewer — Streamlined First Page Loading

We optimized page loading for our Web Document Viewer component:

• The report document generation process now starts automatically on the server (without the startBuild request from the client). As a result, the report's first page appears on the screen almost instantly.
• In single-page mode, the Document Viewer preloads the first 15 pages. Users can browse through these pages while the rest of the document is being built. Use the PreloadedPagesOffset setting to specify the number of preloaded pages.
• In the multi-page mode, the Document Viewer now displays pages immediately in a lower resolution. Users can quickly navigate to a specific report page (without waiting for full resolution pages to load).
• We reduced the value of the throttle to 150ms. Changing the throttle value reduces lag when scrolling through the report. Use the MultipageScrollingThrottle setting to specify the throttle value as needed.

Blog Post

Web Report Viewer — Sign PDF Documents

The signature dropdown editor in the PDF export options pane displays signatures collected on the backend.

DevExpress Report Viewers can now digitally sign exported PDF documents. Implement the IPdfSignatureOptionsProviderAsync interface to pass signatures to the Web Report Viewer.

                        public interface IPdfSignatureOptionsProviderAsync {
                            Task<Dictionary<string, PdfSignatureOptions>> GetAvailableOptionsAsync();
                        }

We added a new CustomizeExportDocumentOnFinish method that allows you to sign exported PDF documents on the backend.

Online DemoExample (GitHub)

Web Report Viewer — Accessibility (Section 508, WAI-ARIA)

We assigned WAI-ARIA attributes to all UI elements in the Report Viewer and improved keyboard navigation between UI elements. The Report Viewer now successfully passes Accessibility Insights and Chrome Lighthouse testing tools.

Online Demo

Web Report Viewer — Asynchronous Document Search

We implemented an asynchronous search in our Web Document Viewer. New search displays the number search results currently found (in real time). Users can stop searching at any time if they do not want to wait for the whole document to be scanned.

New search is enabled by default. Disable the UseAsyncSearch property to enable the previous behavior.

Web Report Viewer — Fetch API (Printing and Data Export)

Our Web Document Viewer now uses Fetch API to send and manage network requests to the server. This allows you to pass request headers from the client application to the backend using a unified method, which improves compatibility with authentication libraries.

                        import { fetchSetup } from '@devexpress/analytics-core/analytics-utils';
                        fetchSetup.fetchSettings = { headers: { Authorization : 'Bearer' + token } };

#Reporting for WinForms and WPF

Report Designer Data Source Wizard – UX Enhancements

We merged the two first pages of the Data Source Wizard. Pages previously used to select data source type and database provider have been replaced with a single page that displays a flat list of all supported data sources:

We also integrated a search bar.

The following Data Source Wizard Customization APIs define a new wizard page:

WinForms API:

• DevExpress.DataAccess.Wizard.Presenters.ChooseDataProviderPage<TModel>
• DevExpress.DataAccess.UI.Wizard.Views.ChooseDataProviderPageView
• DevExpress.XtraReports.Wizards.Presenters.ChooseDataProviderPageEx<TModel>
• DevExpress.XtraReports.Wizards.Views.ChooseDataProviderPageViewEx

WPF API:

• DevExpress.Xpf.DataAccess.DataSourceWizard.ChooseDataProviderPage
• DevExpress.Xpf.Reports.UserDesigner.ReportWizard.Pages.ChooseDataProviderPageEx

We added the UseMergedConnectionTypePage property. Enable this option to switch to the new wizard design.

Documentation: WinForms | Documentation: WPF

#Visual Studio Report Designer

Miscellaneous Enhancements

• You can now use the DevExpress Visual Studio Report Designer in apps that target .NET Framework with the "Use the Windows Forms out-of-process designer for .Net Framework apps" property enabled (available in Visual Studio 2022 preview versions).
• The DevExpress Visual Studio Report Designer now supports apps that target the latest .NET 8 Preview 4.
• The designer process in .NET apps now looks for NuGet packages in a project directory specified by the globalPackagesFolder option in nuget.config.

• We integrated Report Designer Options into Visual Studio options (Tools → Options → DevExpress → XtraReports).

   

  

   

  You can also include Report Designer settings in the export (Tools → Import & Export Settings Wizard).

SqlDataSource — Configure Session

You can set up the SQL connection session before querying the database:

• Set the transaction isolation level for the SqlDataSource using the ConnectionOptions.IsolationLevel property (use the SqlQuery.IsolationLevel property for a SQL query).
• Implement IDBCommandInterceptor or IDBConnectionInterceptor to enable interception, modification, and/or suppression of MS SQL operations. This includes low-level database operations such as executing a command or setting a key-value pair in a session context. You can store the value in the session context and execute any request after the connection is opened.

#ASP.NET Core Dashboard

EFDataSource - Resolve DbContext from Dependency Injection Container

New API allows you to inform the Dashboard control about the appropriate Entity Framework Core connection context.

Register the context in the dependency injection container. Call the AddDbContext method in the ConfigureServices method of the "Startup" class to specify the required connection string:

                        builder.Services.AddDbContext<OrdersContext>(options => options.UseSqlite("MyConnectionString"), ServiceLifetime.Transient);

Implement the IEFContextProvider interface:

                        using DevExpress.Data.Entity;
                        using Microsoft.Extensions.DependencyInjection;
                        using System;
                        // ...
                        public class CustomEFContextProvider : IEFContextProvider, IDisposable {
                            IServiceScope scope;
                            public CustomEFContextProvider(IServiceProvider provider) {
                                this.scope = provider.CreateScope();
                            }
                            public object GetContext(string connectionName, Type contextType) {
                                if(connectionName == "EF Data Connection") {
                                    return scope.ServiceProvider.GetService(contextType);
                                }
                                return null;
                            }
                            public void Dispose() {
                                scope.Dispose();
                            }
                        }

Use the ConfigureServices method of the Startup class to register the DashboardConfigurator service. Use the SetEFContextProvider method to configure the service.

                        services.AddScoped<DashboardConfigurator>((IServiceProvider serviceProvider) => {
                            DashboardConfigurator configurator = new DashboardConfigurator();
                            configurator.SetEFContextProvider(new CustomEFContextProvider(serviceProvider));
                            return configurator;
                        });

Content Security Policy — Suppress Inline Styles and Scripts

We improved Content Security Policy support for our Web Dashboard control in ASP.NET Core applications (you can implement a nonce-based CSP). This allows you to remove the unsafe-inline keyword for style-src and script-src directives from web pages that host the DevExpress Web Dashboard control.

Documentation   Example (GitHub)

#Web Dashboard (HTML/JS)

Conditional Formatting — Create Custom Styles

You can now define a custom style for format rules used within Grid, Pivot, and Card dashboard items. Our Custom Style Settings editor allows you to specify the following style settings:

• Text Color
• Background Color
• Font

Documentation

Data Export — Fetch API

We changed the default implementation of the IRemoteService to use Fetch API. The service implements the communication between the client side and backend of our Web Dashboard Control. You can now pass request headers from the client application to the backend using a unified method, which improves compatibility with authentication libraries.

#WinForms and WPF Dashboard

Dashboard Data Source Wizard — UX Enhancements

We merged the two first pages of the Data Source Wizard. Pages previously used to select data source type and database provider have been replaced with a single page that displays a flat list of all supported data sources.

We also integrated a search bar to quickly locate a required data source.

The following Data Source Wizard Customization API members define a new wizard page in the WinForms Dashboard:

• DashboardChooseDataProviderPage<TModel>
• DashboardChooseDataProviderPageView

We also added the UseMergedConnectionTypePage option for backward compatibility. Disable this option to switch to the previous wizard design.

XAF - Cross-Platform .NET App UI v23.1

#XAF Blazor UI

New Scheduler Module (CTP)

We integrated our Blazor Scheduler component (DxScheduler) within XAF's Blazor UI. Use the Scheduler Module to display and manage XAF Event and Resource business objects within a calendar.

The Scheduler Module is currently available as a Community Tech Preview (CTP).

Getting Started

Form Layout End-User Customization in Detail View

With this new UI/UX option, your users can create and manage their own UI right directly in the Web browser. UI customization (for both developers and users) can be a time saver - customizable Web apps can address changing business requirements without the need for redeployment.

As you would expect, you can disable these advanced customization capabilities for specific users. Use the CustomizationEnabled property in the Model Editor or in code.

Documentation

Filter Editor, Find Panel, and Column Header Filters

XAF's DxGridListEditor and FilterPropertyEditor now integrate a JavaScript-based Data Filtering UI (Filter Criteria Editor), first introduced in our Web Reporting and BI Dashboard products. This new feature supports popular criteria language options based on reference, collection, and scalar/value type properties such as strings, numbers, etc.

The Blazor DxGridListEditor also incorporates the following new filtering options:

• Find Panel
• Column Header Filters.

Multi-Tenancy Module for Blazor (CTP)

It is now easier to create multi-tenant or SaaS-ready XAF Blazor applications (.NET 6+) that target a single database or one database per tenant. You need to write a few declarative lines of code and use a new Multi-Tenancy reusable module (instead of writing hundreds of lines of code).

In v23.1, the DevExpress.ExpressApp.MultiTenancy module is available as a community technology preview (CTP).

Documentation

Colored Icons to Distinguish Key UI Commands

We introduced colored icon support within the main menu toolbar, layout groups and tabs, and the view header (much like XAF WinForms/WebForms counterparts).

We also improved the image picker in the Model Editor and migrated our XAF Blazor images to the DevExpress.Images library.

CRUD Enhancements

• We removed New and Close commands from the root DetailView to save space.
• We added Save & New and Save & Close commands to the root DetailView, keeping the last selection.
• We added new Next/Previous commands for navigating through data records (much like XAF WinForms/WebForms counterparts).

We also added the QuickAccess and Notifications command (action) containers, so you can display built-in or custom commands at the top right corner of your Web application.

Documentation

Form Layout Customization - New API

We implemented a new BlazorLayoutManager.ItemCreated event that allows you to customize DxFormLayout, DxFormLayoutTabPage, DxFormLayoutGroup, and DxFormLayoutItem on creation.

                    private void OnItemCreated(object sender, BlazorLayoutManager.ItemCreatedEventArgs e) {
                        if (e.ModelLayoutElement.Id == "MyTabbedGroup" && e.LayoutControlItem is DxFormLayoutTabPagesModel tabbedGroup) {
                            tabbedGroup.ActiveTabIndexChanged = EventCallback.Factory.Create<int>(this, index => tabbedGroup.ActiveTabIndex = index);
                        }
                    }

And yes, our Blazor Layout Manager now preserves active tab state between sessions.

Documentation

Mail Merge in Rich Text Editor

The Office Module for Blazor now supports mail merge operations within the ASP.NET Core Blazor Rich Text Editor.

Grid List Editor Enhancements

XAF Blazor now supports the following Application Model properties for the ListView node:

• IModelListView.Filter
• IModelListView.IsFooterVisible
• IModelListViewShowFindPanel.ShowFindPanel
• IModelListViewPreviewColumn.PreviewColumn

Property Editor Enhancements

• We supported icons in the Enumeration and Boolean Property Editors - this is helpful to distinguish various event states, priorities, and mode.

  

• Our new Color Property Editor allows you to customize Color properties, for instance, in scheduler resources.

  

• We supported Property Editors for the Label, Status, and Recurrence properties in XAF’s Event detail form.

  

• XAF Blazor v23.1 supports hints for Detail View editors. You can specify the Tooltip property in the Model Editor or mark your business class property with ToolTipAttribute in code.

Content Security Policy (CSP) Support

XAF Blazor UI now supports Content Security Policy (CSP) integration and introduces advanced security features to help you to detect and mitigate certain types of security risks, including Cross-Site Scripting (XSS) and data injection attacks. To make sure XAF Blazor UI supports CSP, we test it through Selenium and internal tests.

#XAF WinForms UI

Form Designer Support for XAF Templates

We added support for XAF form template designers in .NET 6+. If you use .NET 6+, make sure that the DevExpress.ExpressApp.Win.Design NuGet package is added to the SolutionName.Win project.

Documentation: Create a Custom Ribbon Template

Middle Tier Security for EF Core

We added support for Middle Tier Security in EF Core 6.x and 7.x for XAF WinForms and non-XAF apps. As part of this enhancement, we ship our own database provider for EF Core that can work with a remote Middle Tier application server as a database (much like XPO-based Middle Tier Security).

NOTE: XAF WinForms client apps for both EF Core and XPO ORM will enable Middle Tier Security by default in v23.2 for security reasons (to avoid direct database connections and the need for additional protection).

Documentation

Multi-Tenancy Module for WinForms (CTP)

It is now much easier to create multi-tenant or SaaS-ready XAF WinForms applications (.NET 6+) that target a single database or one database per tenant. You need to write a few declarative lines of code and use a new Multi-Tenancy reusable module (instead of writing hundreds of lines of code).

In v23.1, the DevExpress.ExpressApp.MultiTenancy module is available as a community technology preview (CTP).

#Common Enhancements

Support for EF Core 7

We introduced Entity Framework Core 7 (EF Core 7) support. EF Core 7 offers numerous advantages over its predecessor (performance and customization included). And yes, XAF also continues to support EF Core 6.

Why we recommend EF Core over XPO for new development

Dependency Injection in XAF Controllers

We extended support for Dependency Injection (DI) in XAF Blazor and WinForms apps (.NET 6+). With this addition, you can inject arbitrary services into custom constructors of XAF View and Window Controllers.

XAF WinForms apps now provide access to IServiceProvider through XafApplication.ServiceProvider – much like ASP.NET Core Blazor apps. Dependency Injection capabilities are available in a cross-platform module, which simplifies user customizations.

                    using Microsoft.Extensions.DependencyInjection;

                    namespace MainDemo.Module.Controllers;

                    public class TaskActionsController : ObjectViewController<ObjectView, DemoTask> {
                        public TaskActionsController() {
                            new SimpleAction(this, "My Top Right Corner Action", "QuickAccess");
                        }
                        [ActivatorUtilitiesConstructor]
                        public TaskActionsController(ITaskActionsService taskActionsService) : this() {
                            TaskActionsService = taskActionsService;
                        }
                        protected ITaskActionsService TaskActionsService { get; }
                    }

Documentation

Dependency Injection in EF Core and XPO Data Model

We added support for Dependency Injection (DI) at your ORM data model level in XAF Blazor, WinForms, and Web API Service apps (.NET 6+). With this addition, you can use IServiceProvider to access arbitrary services from XAF business classes.

EF Core - Use the IObjectSpace.ServiceProvider property

                    // ObjectSpace in EF Core classes now has the ServiceProvider property.
                    public class Task : BaseObject {
                        public virtual ApplicationUser? CreatedBy { get; set; }
                        public override void OnCreated() {
                            base.OnCreated();
                            var security = ObjectSpace.ServiceProvider.GetRequiredService<ISecurityStrategyBase>();
                            CreatedBy = ObjectSpace.GetObjectByKey<ApplicationUser>(((ApplicationUser)security.User).ID);
                        }
                    }

XPO - Use the Session.ServiceProvider property

                    // Session in XPO classes now has the ServiceProvider property.
                    public override void AfterConstruction() {
                        base.AfterConstruction();
                        var security = Session.ServiceProvider.GetRequiredService<ISecurityStrategyBase>();
                        CreatedBy = Session.GetObjectByKey<ApplicationUser>(((ApplicationUser)security.User).Oid);
                    }

Documentation

Dependency Injection with 3rd-party Inversion of Control (IoC) Service Containers

XAF Blazor, Web API Service, and WinForms .NET 6+ apps can now register their favorite .NET IoC library instead of Microsoft's IServiceProvider. Use the UseServiceProviderFactory extension method of the application builder class.

                        var builder = WinApplication.CreateBuilder();
                        builder.UseServiceProviderFactory(new AutofacServiceProviderFactory());
                        // OR
                        // builder.UseServiceProviderFactory(new DryIocServiceProviderFactory());

.NET App Security & Web API (FREE) v23.1

Swagger Schema Support

DevExpress Web API Service now natively supports the Swagger schema. We also cleared unnecessary/service schemas from the Swagger UI and enhanced overall Swagger UI performance, usability, and ease of use with example input in endpoint descriptions.

OData Entity Model Customization Made Easy

Our Web API Service now includes Fluent-like extensions, which simplifies the following Web API configuration tasks (write a few configuration code lines instead of dozens).

Expose or hide business object properties.

                            // MySolution.WebApi\Startup.cs (MySolution.Blazor.Server\Startup.cs)
                            services.AddXafWebApi(Configuration, options => { 
                                options.BusinessObject<Contact>().ConfigureEntityType(b => {
                                    // Ignore the property of this class.
                                    b.IgnoreProperty(o => o.Email);
                                    // Ignore the property of the parrent `Person` class.
                                    b.IgnoreProperty(o => o.Company);
                                }); 
                            });

Limit or set available HTTP methods/verbs/OData actions for a business object.

                            // MySolution.WebApi\Startup.cs (MySolution.Blazor.Server\Startup.cs)
                            options.BusinessObject<MyEntity>().ConfigureController(b => { 
                                b.ReadOnly();
                                // The above line is equivalent to:
                                // b.WithActions(WebApiActions.ReadOnly);
                            });

CodeRush for Visual Studio v23.1

#Visual Studio ARM Support

CodeRush can now be installed into Visual Studio ARM. ARM support is in beta in this release.

#Code Analysis

New Diagnostics for DevExpress WPF Components

• Use DependencyObjectExtensions.DataContext to define bindings for generated columns
  This diagnostic helps improve performance by defining bindings in column templates using the DependencyObjectExtensions.DataContext attached property. (XAML diagnostic)

  Documentation

• The column's FieldName or Binding property is not defined
  This diagnostic shows when you need to specify the FieldName or Binding property to connect the column to data. To create an unbound column, you can set the FieldName property to a string that does not match an existing field name. (XAML diagnostic)

  Documentation

• Columns with the specified Binding property are read-only
  This diagnostic reveals read-only columns. You can set the binding's Mode property to "TwoWay" to allow users to edit column values. (XAML and C# diagnostic)

• Missing EndUpdate call
  This diagnostic shows BeginUpdate method calls that are missing a subsequent EndUpdate method call, which can result in a control's UI staying locked. (C# diagnostic)

• Missing BeginUpdate and EndUpdate calls
  This diagnostic helps improve performance by calling BeginUpdate and EndUpdate methods to process collection updates in batches. (C# diagnostic)

• BeginUpdate call in a loop
  This diagnostic finds BeginUpdate and EndUpdate methods located inside code loops. Move the calls outside the loops for better performance. (C# diagnostic)

Spell Checker Improvements

Custom spell checker dictionaries stored in the solution-level layer can now be shared among all team members working on that solution (even if their solution root folders are different).

#Navigation

Camel Case Navigation and Selection

Camel Case navigation and selection features now work inside TextBoxes everywhere in Visual Studio, including the following locations:

• Visual Studio's new "Inline Rename" window
• The Solution Explorer (when renaming files)
• The Properties windows (for text properties)
• Search filters

Documentation

Jump Codes

We've released Jump Codes, a new navigation feature for CodeRush that helps you move to any code (in any programming language) that you can see onscreen in just a few keystrokes. Jump Codes can also select code with fewer keystrokes.

Here's how it works:

1. Look (inside any visible code window) where you would like to be.
2. Press Caps+Tab to bring up the UI (enable the Caps as a Modifier if needed).
3. Enter the jump code shown at the target location.
4. Press Enter to land the caret on the target.

Simple enough.

Caps + Tab to invoke, Enter to land the caret (and a jump code in between).

Landing Variations

You can hold down modifier keys to fine-tune your landing, selecting the target, landing on the right side or even inside subsequent parens or brackets.

Multi-monitor Support

The feature lets you jump to any visible code window (from your Visual Studio session), even across multiple monitors. Once the Jump Codes UI is active, you can press Tab to move from monitor to monitor.

Highly Optimized Efficiency

Landing shortcuts are highly optimized and designed to get you get anywhere inside any code window you can see with the smallest amount of physical effort. So not only can you get anywhere using the fewest key presses, you do this with the shortest finger travel distance. That means for many target locations your fingertips will remain on the home row.

And a single letter key press on the home row is all it takes to move the caret to the beginning of most lines in view.

If you are working with a non-Qwerty keyboard layout (such as Dvorak or Colemak), you will want to select your keyboard layout on the Jump Codes options page.

There's more to this feature than just moving the caret. Read Blog Post

#Programming Style

You can now specify whether CodeRush should emit optional parenthesis around switch expression operands (C# 8.0+).

This setting is currently used by CodeRush's "Apply the Optional parentheses style to explicitly specify the order of operations" code cleanup rule.

#Enhanced High DPI Resolution Support

We enabled SVG icons by default across all supported UI controls.

If you prefer PNG icons and want to use them in v23.1+, disable the dxUseVectorIcons option in the initialization section of the main application unit:

                        uses
                            Forms,
                            cxLookAndFeels,
                            // ...
                        begin
                            dxUseVectorIcons := True;
                            Application.Initialize;
                            Application.MainFormOnTaskbar := True;
                            Application.CreateForm(TMyForm, MyForm);
                            Application.Run;
                        end.

In addition to built-in icons displayed at runtime, we replaced numerous PNG icons with SVG equivalents in design-time editors. Please note that this change primarily affects RAD Studio Alexandria 11 IDE because only its latest versions support High DPI environments.

#"Light" Style Rendering

We enabled our "Light" Style rendering mode by default (TdxVisualRefinements.LightBorders := True;).

* To disable Light Style rendering, call the TdxVisualRefinements.Reset procedure or adjust extra paddings and lightweight borders separately.

The following UI controls now support "Light" style rendering:

• TdxListViewControl and TdxShellListView
• TcxPivotGrid and TcxDBPivotGrid
• TcxTreeList, TcxVirtualTreeList, and TcxDBTreeList
• TcxDBVerticalGrid, TcxRTTIInspector, TcxVirtualVerticalGrid, and TcxVerticalGrid
• TcxScheduler
• TcxMCListBox
• TcxListView

#New Windows 11 Theme

Our new WXI skin (theme) is based on Windows 11.

Our WXI theme ships with advanced visual effects and animations. We optimized our rendering engine to address rendering performance and UI/UX flexibility. With this new rendering engine, we'll be able to deliver new vector skins faster and help you ship more modern and elegant user interfaces.

#Chart Control

The DevExpress VCL Chart Control allows you to transform data into its most concise and readable visual representation. This update marks the official release of our VCL Chart Library and incorporates a handful of new features.

If you are ready to explore the capabilities of our VCL Chart control…ready to create/customize your first DevExpress-powered VCL Chart, please review our online documentation for additional information/examples.

Getting StartedBlog Post: Tips & Tricks

Scroll & Zoom

The Chart Control now supports “out-of-the-box” zoom, scroll, and pan operations for XY diagrams.

Resolve Overlapping Labels

The Chart Control can now resolve overlapping labels for pie and doughnut series Views. Use the ValueLabels.ResolveOverlappingMode property to enable/disable this option.

Hit-Testing

New API allows you to identify chart UI elements under the mouse pointer. For example, you can handle the OnHotTrackElement and OnMouseMove events to display custom hints for hot-tracked series values.

                    procedure TFeaturesDemoMainForm.ccDiagramsHotTrackElement(Sender: TObject;  const AArgs: TdxChartHotTrackElementEventArgs);
                    var
                      BarView: TdxChartXYSeriesBarView;
                    begin
                      if (AArgs.HitTest.Diagram = cdVisitors) and (AArgs.HitTest.HitCode = TdxChartHitCode.SeriesPoint) then
                      begin
                        BarView := TdxChartXYSeriesBarView(AArgs.HitTest.SeriesPoint.Series.View); // Active view.
                        // ...
                      end;
                    end;    

Value, Label, and Marker Display Text Customization

Our new OnGetAxisValueLabelDrawParameters event allows you to customize individual labels. For example, you can display different measurement units in value labels based on series values.

                        procedure TFeaturesDemoMainForm.cdAreaGetAxisValueLabelDrawParameters(Sender: TdxChartCustomDiagram; AArgs: TdxChartGetAxisValueLabelDrawParametersEventArgs);
                        begin
                          if AArgs.Axis is TdxChartAxisY then
                            AArgs.Text := FormatSalesAmount(AArgs.Value);
                        end;
