WinForms Controls v20.1

.Net Core 5 Compatibility

We recently switched to 3.1 LTS (Long Term Support) from .NET Core 3. As you may know, we actively track all .NET 5 announcements and make corresponding changes in our WinForms products as soon as possible.

We issued support for both .NET 5.0 Preview 1 and .NET 5.0 Preview 2. All our WinForms products are fully compatible with .NET 5.

Important changes in .NET Core: WinForms deprecated controls removed

We will move forward with official .NET 5 support once the framework is released.

Gantt Control

The WinForms Gantt control was first introduced in October 2019 as a community technology preview (CTP). This update marks its official release.

Task Dependencies: Types, Lags, and Performance Improvements

The Gantt Control now supports different dependency types: start-to-start, start-to-finish, finish-to-start, and finish-to-finish. If the mouse pointer hovers over a dependency arrow, users can move the dependency from one successor to another or remove the dependency. To create a new dependency, use pointers displayed at a task's edge.

To specify dependencies, use a separate data source. A data source record represents a dependency. The record should contain the predecessor, successor, and dependency type. You can also set a time lag between predecessor and successor. If a user moves a predecessor, the control automatically reschedules all its successors with respect to the time lag.

We also improved dependency rendering performance for applications that use large amounts of data.

Demo*: Performance Improvements   Demo*: Dependency Source, Types Lags   Documentation
* Requires installation of WinForms Subscription v20.1+. Download

Interactive Editing

Our WinForms Gantt Control now supports interactive editing. Users can edit tasks in the chart and task areas. In the task area, users can invoke a cell editor to update a task's start/finish date, progress, or duration. In the chart area, users can move a task to a new time slot, update progress, or change a dependency via drag and drop. Changes in the chart area are automatically reflected in the task area, and vice versa.

Asynchronous Document Generation and Export API

Our Document Viewer components can now create, print, and export report documents in a separate thread. This feature is enabled by default for the DevExpress Visual Studio Report Designer and WinForms End-User Report Designer preview tab. Enable the following properties before you assign a report to Document Viewer (this will enable the feature for your application):

WinForms

  • The 'DocumentViewer.UseAsyncDocumentCreation' property
  • To create a ReportPrintTool class instance, use the new ReportPrintTool(XtraReport report, bool useAsyncDocumentCreation) constructor

WPF

  • The 'DocumentPreviewControl.UseAsyncDocumentCreation' dependency property
  • Or use the following style:
    • XAML
    <Style TargetType="{x:Type dxp:DocumentPreviewControl}">
        <Setter Property="UseAsyncDocumentCreation" Value="True" />
    </Style>
    

The desktop application's main thread remains intact when these operations run in the background thread. This allows users to interact with the user interface. The progress bar displayed in the Document Viewer's status bar now reflects the current operation and allows users to cancel it.

.NET Reporting | DevExpress

The document generation engine is now independent of the Application.Idle event call sequence. This makes the component interface more responsive and is also helpful if you develop add-ins for external applications like Microsoft Office.

This enhancement also offers a way to create, print, and export report documents in an asynchronous manner via the following new API:

  • the 'CreateDocumentAsync' method;
  • the 'PrintAsync' method.

We also implemented asynchronous counterparts for export methods (e.g. ExportToPdfAsync, ExportToXlsxAsync, etc).

SqlDataSource Filtering - Compare a Multi-Value Report Parameter with Null Value

You can now use the following filter string for 'SelectQuery' either to display the entire set of data source records or only those selected in a multi-value parameter drop-down editor:

?catID Is Null Or CategoryID In (?catID)

Documentation

Web Reporting

Web Report Designer - Field List Performance Enhancements

We introduced the following enhancements to the Field List engine:

  • The Report Designer now sends a single request to a web-server at initial rendering (to discover Field List nesting levels).
  • The Field List now loads its elements on demand. This reduces possible delays when searching through field list items and helps avoid browser lock-up for extremely large and complex data sources.

Documentation

Expression Editor - Comments and Line Breaks

Expression text can now contain comments, newline and space characters to improve readability for complex expressions.

Miscellaneous Enhancements

  • The Web Report Designer's Data Source Wizard allows you to search through the list of available connections. Documentation
  • We updated CSS styles used in Document Viewer and Report Designer to address conflicts with Bootstrap CSS styles. As a result, both components will now appear and render correctly when used in a Bootstrap-based application.

Documentation

Tab Item – Performance Optimization Mode

We added new options for WinForms and WPF platforms so you can configure how Dashboard Items within Inactive Tabs are loaded during the first data load – always or on demand. Please note the documented restrictions on the Dashboard Items load order. We must always load data for Master Filter Item, even when it's placed on the Inactive Tab.

In Web, we permanently changed the Dashboard Item's loading order to make sure the visible items are always loaded and rendered first.

WinForms Documentation   WPF Documentation

Data Export

Export Customization API

v20.1 includes our new Export Customization API. Now, you can maintain maximum customization of XRControls. For this release, we chose to extend support for our most popular UI controls - Charts and Gauges. One of the entry points to the new API is the GetPrintableControl method. We updated the CustomerSupport demo to demonstrate this new approach. You can find it in the Dashboard Demo Center.

Visual Warning in Expression Editor

We added a visual indicator – a warning – to our WinForms Expression Editor. This indicator warns users that wish to execute [int] / [int] division – an action that can produce unexpected results. Some users may expect Excel-like behavior [int] / [int] = [double] (i.e. 10 / 4 = 2.5) in this scenario.

As you may know, we historically stick to the .NET C# [int] / [int] = [int] approach in this situation (i.e. 10 / 4 = 2). This difference can obviously lead to data loss and as such, we decided to add a warning when [int] to [int] division is created in an Expression.

Visual Warning in Expression Editor - WinForms Dashboard | DevExpress

WinForms State Management – Lifecycle

We implemented a new DashboardStateChanged event. The Dashboard Viewer and Dashboar Designer fire this event each time a dashboard state changes.

We now calculate the layout of a printed document more accurately. The resulting printout closely mirrors the print output of Microsoft Excel.

For backward compatibility, use the SpreadsheetCompatibilityOptions.EnableLegacyPrintLayout option.

Print Layout Enhancements - Spreadsheet Document API | DevExpress

Calculation Accuracy

We significantly improved calculation accuracy for comparison operators and the following built-in functions:

  • ROUND, ROUNDUP, ROUNDDOWN, FLOOR (number rounding now replicates Microsoft Excel)
  • Date and time functions (WEEKNUM, YEARFRAC, DATEDIF, NETWORKDAYS.INTL)
  • Mathematical functions (SUM and AVERAGE)
  • Financial functions (EFFECT)

The impact of regular floating point operations on calculation accuracy can be significant. In addition to standard floating point operations, we used math algorithms to match Microsoft Excel as much as possible. Feel free to compare our new Spreadsheet File API to the competition and tell us where we stand.

ASP.NET Core Blazor Server UI (CTP) supports XPO ORM classes for data access and helps you create fast and mobile-friendly Web apps. This preview ships the following functionality for desktop and mobile browsers:

  • Multiple UI themes and a runtime theme chooser;
  • Navigation control with a hierarchical tree structure;
  • Menus with all standard XAF command types (buttons, popups, input/search boxes, drop-down menus);
  • Grid List Editor with sorting, grouping and paging;
  • Detail form layout with group and tab controls;
  • Property Editors for all data types (no advanced editors for criteria, RTF, etc.);
  • Simple Forms Authentication with a login and password, role-based authorization and basic user, role and permission management in the UI.
  • A separate 'DevExpress v20.1 XAF.Blazor Solution Wizard' template to help you create and test new projects in Visual Studio 2019 (v16.4 or later).

We do not recommend use of our new Blazor UI for production code. We've made it available to gather feedback and engage those of you considering it for future use.

Core Enhancements

Security Permissions for Actions

Security Permissions allow users to prohibit execution of both custom and XAF system Actions in WinForms and ASP.NET applications. This feature ships with the following options:

  • Security permissions hide or deactivate UI Actions unconditionally.
  • Users can quickly locate required Actions via search and grouping (for instance, to filter out system Actions like Logon and Refresh).
  • Users can group data by display text, category, module and other context information.

Security System for Entity Framework Core

Our goal is to help DevExpress and non-DevExpress customers benefit from XAF's Security System and Entity Framework Core. In v20.1, we've added a secured Object Space for EF Core 3.1+ and demonstrated its use for basic CRUD operations in Console and WinForms applications.

For more information on XAF's user authentication and group authorization APIs for .NET Core and .NET Framework apps, please refer to this GitHub repo.

Video Overview | FAQ

Simplified .NET Core 3.1 WinForms Assemblies and NuGet Packages

We eliminated .NET Core 3 versions of platform-agnostic XAF assemblies in favor of corresponding .NET Standard assemblies (except EF6 and Scheduler assemblies). We've done this for easier project maintenance, clearer dependencies, and future code extension of .NET Core apps and corresponding NuGet packages.

This release makes it easier to complete common development tasks like sharing Class Libraries with DevExpress Data or XPO dependencies for different Target Frameworks.

Documentation

Model Editor for .NET Core and .NET Standard Projects (CTP)*

XAF includes a preview of the Model Editor for .NET Core 3+ (WinForms) and .NET Standard 2.0+ (Blazor) projects. Technically, it is a standalone Model Editor tool that runs as a separate process and draws itself inside the Visual Studio frame.

We took this approach so we could limit the impact of issues related to Component designer support in .NET Core projects and to have full control over designer performance, stability, etc.

* Requires installation of .NET Core 3.1. Download

Performance Enhancements

Asynchronous Data Loading in WinForms List and Detail Views (CTP)

GridListEditor in Client DataAccessMode and DetailView can now load data asynchronously in XPO-based apps. The UI continues responding to user actions as data is being retrieved. You can cancel the load operation by closing the View or navigate to another View (in MDI mode).

Documentation

New ServerView and InstantFeedbackView Data Access Modes for WinForms List View (XPO Apps)

With this release, XAF GridListEditor uses read-only server mode components (XPServerModeView and XPInstantFeedbackView) in ServerView and InstantFeedbackView modes.

New data access modes handle large data sources with lower memory usage because they don't load entire instance of the persistent object.

Documentation

UX Improvements

Enhanced Filter Editors for WinForms

XAF Grid, Tree and Pivot List Editors, Report and Dashboard designers now use an enhanced Filter Editor with a new display style, functions and skin support by default.

Documentation

Enhanced Filter Editors for WinForms - XAF | DevExpress

Non-Persistent/Proxy Object Enhancements

  • The IsNewObject function criteria operator supports non-persistent and Entity Framework objects.
  • NonPersistentObjectSpace tracks changes for non-persistent objects and supports filter and sort operations in List View.
  • Parent NonPersistentObjectSpace reloads and disposes its inner Object Spaces.

Documentation

NullText Property in the Platform-Agnostic PropertyEditor Class and Model Editor

We implemented a NullText property in our platform-agnostic PropertyEditor class and Model Editor. Use this property to specify the hint displayed when the editor's value is null or empty.

Documentation

Simplified Access to Detail View Editors

With this release, you don't need to handle 'ViewItem.ControlCreated' and other event handlers for many common usage scenarios. Use our 'DetailView.CustomizeViewItemControl' method to customize View Item controls. You no longer need to unsubscribe from events or check whether controls are created.

Documentation

Data Access v20.1

XPO - ORM Library

Database Schema Migration (CTP)

With this release, you can incrementally update database schema and preserve existing data after changes are made to an XPO data model. You can generate diffs (the SQL script) between the latest data model and existing database schema in the ORM Data Model Designer or in code. Database schema migration is available as a community technology preview.

Documentation

Database Schema Migration - XPO | DevExpress

SQL Server and Always Encrypted Support

In this release, XPO adds support for Always Encrypted for SQL Server 2016+. You can now read, update, sort and filter encrypted column data (the last two operations are driven by encryption mode).

Documentation

Microsoft.Data.SqlClient Support

XPO now supports the Microsoft.Data.SqlClient driver. Microsoft recommends this driver instead of System.Data.SqlClient for new .NET Framework and .NET Core projects. Going forward, Microsoft will also only support new SQL Server features in Microsoft.Data.SqlClient.

VCL Controls v20.1

DirectX Hardware Acceleration

With this release, our VCL Tile, Tile Bar, and Gallery controls support DirectX hardware acceleration. With DirectX, they will perform at their very best on high-DPI devices (4K+). Depending on the number of visual elements, hardware configuration, OS and driver versions, DirectX rendering is up to 3 times faster than GDI.

You activate the desired render mode via a new option in a skin (or look&feel) controller or a control's look&feel settings. The cxDefaultLookAndFeelRenderMode global constant in the source code allows you to select the render mode used by default.

Our DirectX support requires the Windows 7 Platform Update (with DirectX 11), Windows 8, or newer. A control that fails to create a DirectX-specific context uses GDI instead.

Fluent Design Form

v20.1 ships with a new Fluent Design Form that is inspired by Microsoft's Fluent Design System. Its features include:

  • Hamburger Menu/Accordion View Integration.
  • Adaptive Layout.
  • Acrylic Material (a semi-transparent texture).
