Editors

New Mask API for Text Editors – Create Advanced Masks

We continue to refine our mask engine so you can fully control data entry within your WinForms app. v22.1 includes the following update to our WinForms Text Editors mask API. With this new API, you can create reusable masks with custom input logic.

DevExpress WinForms text editors now ship with a EnableCustomMaskTextInput method. This method allows you to override default text processing logic. The method takes a lambda expression as a parameter:

  • C#
                        public void EnableCustomMaskTextInput(
                            Action<CustomTextMaskInputArgs> onTextInput,
                            object tag = null
                        )

The onTextInput parameter includes properties that allow you to obtain an input string, action type, character casing, caret position, selection, etc.

  • C#
                        textEdit1.Properties.EnableCustomMaskTextInput(args => {
                            // Process user input
                        });

With its 'SetResult' method, you can specify actual editor text, selection anchor, and cursor position. To cancel user input, simply call the 'Cancel' method.

  • C#
                        using System.Globalization;
                        using System.Globalization.CultureInfo;

                        textEdit1.Properties.EnableCustomMaskTextInput(args => {
                            if(args.IsCanceled)
                                return;
                            // Converts user input to Title Case
                            var titleCaseResult = InvariantCulture.TextInfo.ToTitleCase(args.ResultEditText);
                            args.SetResult(titleCaseResult, args.ResultCursorPosition, args.ResultSelectionAnchor);
                        });

We also give you the ability to apply custom masks to multiple text editors. The following document describes how to register a custom mask within your WinForms application. Once the custom mask is registered, it is available for use in our Mask Editor for Visual Studio.

The 'name' attribute references a repository item by name. The 'value' attribute specifies the data field name.

  • HTML
                        <div class='default-avatar-container' hidden='${HasPhoto}'>
                            <input class='default-avatar' name='pictureEdit' value='${Photo}' />
                            <a class='choose-photo' id='choose_Photo'>Choose a photo</a>
                        </div>
                        <div class='default-avatar-container avatar-container' hidden='${IsDefaultPhoto}'>
                            <input class='avatar' name='pictureEdit' value='${Photo}' />
                        </div>
                        <div class='input-box'>
                            <input class='input' name='emailEdit' value='${Email}'/>
                        </div>

  • background-position
  • background-size
  • background-repeat
 

Data Grid

New Filters - InRange and InDateRange

We added two new range filters to our WinForms Data Grid, Tree List, Pivot Grid, Vertical Grid, and Filter Control:

  • InRange(value, from, to) filter is equivalent to 'from <= value && value < to'
  • InDateRange(dateValue, from, to) filter is equivalent to 'GetDate(from) <= dateValue && dateValue < AddDays(GetDate(to), 1)'
 

InRange and InDateRange Filters - WinForms Data Grid | DevExpress

 

Data Filtering - Format Operand Values in Custom Functions

We added a new 'ICustomFunctionDisplayAttributesEx' interface. Use its 'GetOperandDisplayValue' method to format the operand's value or provide a custom display text for it.

  • C#
                        public string GetOperandDisplayValue(object value, string displayText) {
                            return string.DisplayFormat("{0} days", value?.ToString());
                        }
 

Filter Control - New Events and Behavior

New events include:

  • CustomValueEditor - Allows you to assign a custom editor to display and edit an operand.
  • CustomValueEditorForEditing - Allows you to specify an editor used to edit an operand.
  • ValueEditorShown - Fires after the editor used to edit a value operand is invoked and allows you to customize editor settings.

The BeforeShowValueEditor event is now obsolete.

Breaking Change:

T1083237 - Text editors used to create and edit filter expressions within the Filter Control now accept values that exactly match corresponding data field type.

You can now specify search panel width/height in relative units. This enhancement maintains a consistent look-and-feel on displays with different DPI scaling.

Documentation

 

Breaking Change:

T1068618 - The ShowSearchPanel property is now obsolete.

 

Support for PerMonitorV2 Scaling

We addressed issues related to mixed-mode DPI scaling. We changed measurement units that specify the size of map elements. The following properties are now measured in DIPs (device-independent pixels). This improvement allows map elements to maintain their physical size on displays with different DPI scaling.

The size of the following map elements is now measured in DIPs:

  • Minimap
  • Legend Markers and Text
 

Breaking Change:

T1069120 - Some properties are now measured in DIPs

Accessibility

Customize Accessibility info for all DevExpress Controls

We introduced a new static 'DXAccessible.QueryAccessibleInfo' event that serves as a single entry point to customize accessibility info for all DevExpress controls in your WinForms application. If you use controls from multiple assemblies in your app (e.g. Data Grid, Editors, Charts, PivotGrid), the QueryAccessibleInfo event will be fired for each control.

  • C#
                        using System.Windows.Forms;
                        using DevExpress.Accessibility;
                        //...
                        public XtraForm1() {
                            InitializeComponent();
                            DXAccessible.QueryAccessibleInfo += OnQueryAccessibleInfo;
                        }
                        void OnQueryAccessibleInfo(object sender, object sender, DXAccessible.QueryAccessibleInfoEventArgs e) {
                            if(e.OwnerControl == gridControl1)
                                if(e.Role == AccessibleRole.Row)
                                    e.Name = "my row text";
                        }

Note: the 'QueryAccessibleInfo' event is a weak event. You should declare its handler as a method in the form class. Otherwise, garbage collection can occur.

 

Common Enhancements

We added the 'AccessibleName', 'AccessibleRole', 'AccessibleDescription' properties to the following classes:

We also introduced the 'AccessibleRole' property for the following components:

We reviewed our Data Grid, TreeList, Data Editors, Ribbon, Bars, Accordion, Layout Control, and Dock Windows for possible accessibility issues. These UI controls now have the right UI Automation properties and generate the expected events.

 

Breaking Changes

  • T1088753 - Accessible Names and Roles have been changed.
  • T1077760 - The UseTextForAccessibility control style is now disabled.
 

Disable Accessibility for All DevExpress Controls

A new static WindowsFormsSettings.DisableAccessibility property allows you to disable 'DevExpress' accessibility for all DevExpress controls in your WinForms application.

We also added a new static SuppressExcessiveAccessibilityNotifications option. This option allows you to enable/disable accessibility events on mouse hover when Windows Narrator's 'Read and interact with the screen using the mouse' setting is turned off. This behavior is supported by our WinForms Data Grid, Verticel Grid, and TreeList controls.

Breaking Change

T1093716 - DataGrid, TreeList, and Vertical Grid controls no longer send accessibility notifications on hover

 

Code Diagnostics (CTP)

You can now detect C# code errors as you type. You can check errors (if any) in the code editor and in the Error List window.

                        public class ViewModel : ViewModelBase {
                            //...
                            [Command]
                            public void ValidateRow(RowValidationArgs args) {
                                var item = (Customer)args.Item;
                                if(args.IsNewItem)
                                    _Context.Customers.Add(item);
                                _Context.SaveChanges();
                            }
                            [Command]
                            public void ValidateRowDeletion(ValidateRowDeletionArgs args) {
                                var item = (Customer)args.Items.Single();
                                _Context.Customers.Remove(item);
                                _Context.SaveChanges();
                            }
                            [Command]
                            public void DataSourceRefresh(DataSourceRefreshArgs args) {
                                _ItemsSource = null;
                                _Context = null;
                                RaisePropertyChanged(nameof(ItemsSource));
                            }
                        }

Save / Restore Layout

You can now save and restore the Blazor Data Grid's layout as requirements dictate. Layout information includes the current page, column sort order/direction, column position, filter values, and grouped columns.

Server Mode Data Source

The DevExpress Blazor Grid now supports our Server Mode data source for Blazor Server-based applications. This data source was designed to maximize performance against large data collections.

In Server mode, our Blazor Data Grid loads data in small portions, on demand. This helps reduce memory consumption and improve overall app performance.

All data shaping operations (like grouping and sorting) are delegated from the Blazor application itself to underlying services (such as EF Core, XPO, etc.). These services process data shaping operations much more efficiently and help deliver a major boost in performance. Documentation

                                // ...

We also removed the 'PlatformApplication.designer.xx' and 'Module.designer.xx' files from the Solution Wizard template in .NET 6 apps. These changes will not break your apps for the .NET Framework. You can continue to use our Application and Module Designers.

  • XAF0012: Avoid calling the 'XafApplication.CreateObjectSpace()' method overload without the 'Type' parameter.
  • XAF0013: Avoid reading the 'XafApplication.ConnectionString' property.
  • XAF0014: The property with the 'Association' attribute must have a correct unique pair.
  • XAF0015: Association must not have the 'Aggregated' attribute if it is paired to the 'many' end of the association.

CodeRush for Visual Studio v22.1

Performance Enhancements

Improved Startup Performance

We have improved startup performance by lazy-loading resources and settings, asynchronous initialization of internal services, reworking the way CodeRush interacts with Visual Studio menus and toolbars, and optimizing memory use.

 

Optimized Debug Visualizer

The Debug Visualizer steps over code faster, (due to optimized communication with Visual Studio’s debugging services). We also decreased the time required to render Debugger Visualizer visual elements.

 

Optimized Tool Windows

The Code Issues, Test Runner and Feature Advisor windows now load faster when run the first time.

 

Code Analysis

XAML Diagnostics for DevExpress WPF Components

CodeRush Code Analysis Engine can now check your XAML code for usage errors. This release introduces the following diagnostics for DevExpress Controls:

  • Legacy drag-and-drop - Drag-and-Drop Managers are a legacy way to enable drag-and-drop. Consider setting the 'DataViewBase.AllowDragDrop' property to 'true' instead.

    Documentation

  • ColumnBase.EditTemplate is used - The 'EditTemplate' property is outdated. Consider using CellEditTemplate instead.

  • FieldName matches the Binding path - When the Binding property is specified, 'FieldName' should not contain an existing property name.

    Documentation

  • Outdated windows The DXWindow, DXRibbonWindow, and DXTabbedWindow classes are outdated. Use ThemedWindow instead.

  • Cell templates missing PART_Editor - Consider setting the editor’s Name to 'PART_Editor' to automatically bind and configure the editor.

    Documentation

  • EditValueChanging/EditValueChanged is handled in CellTemplate - Due to the grid's virtualization mechanism, this event handler will be invoked whenever a user scrolls data. Consider handling 'CellValueChanging/CellValueChanged' (for the grid's View) instead.

    Documentation

  • An invalid EventToCommand.EventName - The EventToCommand's associated object is missing the event specified in EventName.

    Documentation

  • In-place editing is unavailable when NavigationStyle is set to Row or None - Setting the 'ColumnBase.AllowEditing' property to 'true' will have no effect if the 'DataViewBase.NavigationStyle' property is set to 'Row' or 'None'.

    Documentation

  • AutoWidth and relative column size are used together - Setting the relative (star) column size will have no effect if the 'TableView.AutoWidth/TreeListView.AutoWidth' property is set to 'true'.
