WPF Controls v25.1.2 Release

A new WPF Controls release is now available. 

Detailed Update List

Bars

• Added RibbonViewModel.SelectedItem property for the currently selected RibbonTabViewModel.
• Added an InvocationFocusBehavior property to most bar controls that determines how focus should be handled following the primary invocation of the control.
• Added DockableToolBarSerializerOptions.IsVisible flag to serializer/deserialize dockable toolbar visibility with layouts.
• Improved RibbonGallery keyboard navigation to better match Office behavior.
• Fixed an issue introduced in the previous build where XAML-defined ribbon gallery popups didn't render the implicit menu gallery correctly.
• Fixed an issue where galleries would incorrectly call the Execute method for preview events when RoutedCommand-based commands were used.
• Fixed an issue where in-ribbon galleries that were updated when their parent tab was not selected may not invalidate measurement.
• Fixed an issue restoring the location of a floating DockableToolBar in certain mixed DPI environments.
• Fixed an issue dragging a floating DockableToolBar in certain mixed DPI environments where the initial floating location would shift on mouse down.
• Updated the DockableToolBarHost.MenuOpening event to be raised when opening the options menu of a floating DockableToolBar.
• Updated RibbonBackstageTabViewModel so the Content property will default to itself. This improves the default experience of configuring data templates for each tab and makes it easier to see when a data template is not currently configured.

Charts

• Updated ChartMarker to be assigned the XYDataPoint data context for which it is created, which allows index or information from the original data to be retrieved and used in a custom marker template.

Docking

• Updated the DockSite.DocumentItemsSource and ToolItemsSource properties to use weak event handlers for INotifyCollectionChanged.CollectionChanged events.
• Updated StandardSwitcher item focus logic to work around a possible problem with DataGrid, when hosted within docking windows.
• Fixed an issue introduced in a previous build where dragging to float a docked window may not retain a similar size.
• Fixed an issue where dragging to float a docked window in a non-native WPF application context (e.g., MFC hosted) would not apply the proper DPI scale.
• Fixed an issue where non-live splitters in a non-native WPF application context (e.g., MFC hosted) would not apply the proper DPI scale.

Editors

• Added a CanSwatchStretch property to the ColorEditbox and BrushEditBox controls, which determines if the swatch stretches horizontally when the HasText property is false.
• Updated EnumEditBox, EnumPicker, and EnumListBox to have optional support for picking null as a value via new IsNullAllowed properties, useful when a nullable enumeration property is bound to the control's value to indicate a not-set state.
• Added NullValueText properties to EnumEditBox, EnumPicker, and EnumListBox, which allows the picker text representing a null value to be altered.

Grids

• Improved the rendering logic for tree lines.
• Updated TreeListBox.InvalidateChildren to retain the selection when possible.
• Updated TreeListBox logic for item searching by path.
• Updated TreeListBox selection logic for when an item is removed.

Ribbon

• Added a context menu to the empty area of tab content.
• Updated automatic ribbon-oriented context menus to not open for controls in the app menu's additional content area.
• Updated ColorPickerGallery items to use more high contrast border colors for states.

SyntaxEditor

• Updated the Theme Designer application to output numbers in code using invariant culture.
• Fixed an issue with how the view line manager dealt with special control characters at the end of a line.

.NET Languages Add-on

• Added the static CSharpLexer.OtherPreprocessorDirectives property, which allows additional custom preprocessor directives to be supported.
• Improved the C# resolver to better handle is pattern variable declarations in certain scenarios.
• Improved the C# parser's logic for handling local functions.

Python Language Add-on

• Improved Python code outlining to create nodes for all block statements, list expressions, and dictionary expressions.

Themes

• Updated the native ComboBoxItem template to better differentiate between selected and hover states.
• Updated the native ComboBox styles to properly clip drop-down button glyphs.

Views

• Added SettingsExpander properties ExpanderIcon, ExpanderIconTemplate, ExpanderIconTemplateSelector, and IsExpanderIconVisible that can be used to customize the appearance of the expansion indicator.

Shared

• Improved the crispness of rendered rectangles.
• Fixed an issue where UserPromptBuilder would not properly size a user prompt if the startup location was configured as CenterOwner and the owner could not be resolved.
• Fixed an issue where an exception might be thrown when attempting to setting UserPromptWindow.Title if the title could not be resolved.
