WPF Controls v22.1.3 Maintenance Release

A new WPF Controls maintenance release is now available.

Detailed Update List

Docking

• Added a Float All menu item to tabbed MDI tabs, which floats all docking windows in the container together.
• Improved the target dock host hit-test logic.
• Improved focus tracking related to WebView2 controls.
• Increased the default TabbedMdiHost.MaxTabExtent width, and added remarks to its API documentation.
• Updated tool window-only layout deserializations to not clear lazy-load data for document windows.

Editors

• Added the AutoCompleteBox.PopupHeader, PopupHeaderTemplate, and PopupHeaderTemplateSelector properties that allow for injecting a header above the popup's suggestion list.
• Fixed an issue where the initial move of the ColorPicker thumb within its SaturationBrightnessPicker might not yield the correct Value.
• Fixed an issue where certain ColorPicker color component properties might not yet be updated when the ValueChanged event fires.

Grids

• Fixed an issue where a dragged TreeListBox item wasn't focused after drop.
• Fixed an issue where category editor child controls might not allow certain keys to be typed.
• Reverted the previous build's UIA peer updates for TreeListBox/TreeListView/PropertyGrid items since they could cause runtime performance issues when there were many items.
• Updated property grid item UIA peers to return their full path in the AutomationId property.

Ribbon

• Updated the small/medium variant SplitButton template to better support a large CornerRadius setting.
• Consolidated usage of SystemParameters.IsMenuDropRightAligned to use MenuDropAlignment instead.

SyntaxEditor

• Added the EditorCommands.AddNextOccurrenceToSelection edit action (bound to Ctrl+D by default), and the related IEditorViewSelection.AddNextOccurrence method. This new feature adds the next occurrence of the currently-selected text to the selection, or selects the current word if there is no selection.
• Refactored the IntelliPrompt completion session's Shorthand item matcher algorithm, resulting in a significant performance improvement, especially when used with the CanFilterUnmatchedItems option.
• Improved word-wrapped view lines to indent under their primary view line based on a new configurable SyntaxEditor.WrappedLineIndentAmount property. Updated the Word Wrap QuickStart to show off the new property.
• Improved vertical scrollbar handling logic.
• Improved word selection logic.
• Improved selection update logic when the RetainSelection option is used.
• Improved squiggle line rendering performance.
• Updated non-editable code snippet fields to not be highlighted in the template session.
• Updated the CollapsedRegionManager.GetVisibleOffset method logic.
• Fixed an issue where an IntelliPrompt popup displayed near the bottom of a screen could slightly overlap the current view line.
• Fixed an issue where code outlining nodes created with AutomaticOutliningUpdateTrigger.TextChanged may not update correctly when making a large number of text changes.
• Fixed an issue where CodeSnippetSerializer didn't save the Literal tag's Editable attribute with the correct name.
• Fixed an issue where scrolling a non-100% ZoomLevel editor before it's loaded might not scroll to the correct location.

.NET Languages Add-on

• Improved name resolution logic when there are type and namespace name conflicts.
• Improved IntelliPrompt completion for VB With statements.
• Updated BinaryAssemblyLoader to handle TypeLoadException when querying exported types.

Python Language Add-on

• Fixed an issue where an IVariableDefinition might not have its declaring module or text range properties set in a certain scenario.

Web Languages Add-on

• Refactored the XML text formatter with improved logic.

Themes

• Updated the Theme Designer app's Base Color Finder tool to support dark themes.
• Updated WindowChrome shadow positioning logic when dealing with multiple monitors that have different DPIs.
• Updated the custom-rendered WindowChrome shadow to not be included in screen captures.
• Updated menu item templates to make use of a new ResizablePopupContentHost primitive.

Shared

• Updated how CanvasControl handles rendering transparent colors.
• Fixed an issue where PopupButton.StaysOpen was not keeping a Popup open on focus loss properly.
