A major new version of the Actipro WPF controls is now available.

Detailed Update List

Charts

  • Added new AggregationKind.SignedMaximum and AggregationKind.SignedMinimum which compare against absolute values while retaining the sign of the original value; e.g., -5 is greater than 4.
  • Refactored internal data processing logic to support more data types and throw InvalidOperationException for unsupported types.
  • Fixed an issue with AggregationKind.Average where the first value in the set being aggregated might not be properly applied to the final average.
  • Fixed an issue with AggregationKind.Average where DateTime value types might be converted to Int64 value types.
  • Fixed an issue with XYDataPointCollectionView throwing DivideByZeroException when initialized with zero for optimal aggregation count.

DataGrid

  • Improved the various predefined columns that integrate Editors controls into DataGrid to pass updated column property values onto the generated Editors controls.

Docking

  • Improved how focus is applied to TreeListBox controls when a docking window is activated.

Editors

  • Added a PartEditBoxCommitTriggers.LostFocus option so that commit on focus loss is now optional, which is a breaking change since it previously always occurred. The Default and All options have been updated to include LostFocus so they operate like before. If you use any other custom options, you must also now include the LostFocus option to retain the same behavior as before.
  • Renamed the PartEditBoxCommitTriggers.None option to Manual. The previous None option implicitly committed on focus loss. Use the new LostFocus option instead of None to retain the same behavior as before.
  • Updated the numeric edit boxes to support input of Full-width and Arabic-Indic digits.

Gauge

  • Renamed 'ToggleSwitch' as 'FlipSwitch' to avoid ambiguity with new 'ToggleSwitch' control. See the 'Converting to v21.2' documentation topic for information on breaking changes.

Grids

  • Added the TreeListBox.FilterApplied event that is raised after the current filtering state has been applied to all of the control's items, generally occurring when DataFilter is changed, or filtering is enabled or disabled.
  • Added a TreeListBoxItemAdapter.GetAbsolutePath method that can be implemented to improve performance in large trees when searching for a tree node.
  • Improved TreeListBox item focus tracking in response to selection changes.
  • Improved TreeListBox when filtering with DataFilterResult.IncludedWithDescendants to only ensure items included by the filter are made visible via expansion, instead of all descendants.
  • Improved PropertyGrid to support watching collection properties that use EnableCollectionSynchronization.
  • Fixed a bug where the TreeListBox.InvalidateChildren method didn't properly reinitialize the node's children in a certain scenario.
  • Fixed a bug where the PropertyGrid.ChildPropertyRemoved event wasn't being raised appropriately.

MicroCharts

  • Added new MicroAggregationKind.SignedMaximum and MicroAggregationKind.SignedMinimum which compare against absolute values while retaining the sign of the original value; e.g., -5 is greater than 4.
  • Refactored internal data processing logic to support more data types and throw InvalidOperationException for unsupported types.
  • Fixed an issue with MicroAggregationKind.Average where the first value in the set being aggregated might not be properly applied to the final average.
  • Fixed an issue with MicroAggregationKind.Average where DateTime value types might be converted to Int64 value types.
  • Fixed an issue with MicroXYDataPointCollectionView throwing DivideByZeroException when initialized with zero for optimal aggregation count.

Navigation

  • Added the ZoomContentControl.ZoomLevelChanged event.
  • Updated Breadcrumb to stop reopening drop-down menus on button mouse over when a menu is closed via the Esc key.

Ribbon

  • Added the Ribbon.IsToggleMinimizationButtonVisible property to determine if the toggle minimizable button is visible when the Ribbon is minimizable.
  • Improved built-in context menu display logic.
  • Fixed an issue where the title bar quick access toolbar wouldn't show key tips for its children.

Shell

  • Fixed a bug where ShellTreeListBox's handling of an external selection change could lead to excessive processing in a certain scenario.

SyntaxEditor

  • Added a Drag and Drop QuickStart to demonstrate multiple interaction models and features.
  • Added support to customize drag/drop text when dragging within the same editor.
  • Added an Editor Views - Synchronization QuickStart to demonstrate synchronizing the scroller, splitter, and zoom level of one editor instance with another.
  • Added new non-generic interfaces ITaggerBase (implemented by ITagger<T>) and ITagAggregatorBase (implemented by ITagAggregator<T>) for a type-safe way of working with these types when the type of ITag is not relevant.
  • Added ITaggerBase.NotifyTagAggregatorAttached and ITaggerBase.NotifyTagAggregatorDetached which are called when an instance of TagAggregatorBase<T> attaches to or detaches from a tagger.
  • Added CanKeepCaretVisible property to ScrollDownAction and ScrollUpAction to control if the caret should optionally be moved to remain visible after scrolling. Corresponding overloads added to IEditorScrollViewer.ScrollDown and ScrollUp methods.
  • Added various IQuickInfoSession.Placement* properties that return values if the placement-oriented Open method was used to open the session. Updated the IntelliPrompt Quick Info QuickStart to demonstrate repositioning the QuickInfoSession.PlacementRectangle property for these kinds of sessions as the view is scrolled.
  • Improved the vertical scrollbar behavior when dealing with collapsed regions.
  • Improved the positioning logic for IntelliPrompt popups, especially on tablet PCs with right-handedness set.
  • Improved the logic for the EditorSnapshotChangedEventArgs.TypedText property to remove whitespace that might have been added to pad a typed character for proper virtual space positioning.
  • Updated the Language Designer app to support creation of AST node interfaces.
  • Updated drag-and-drop behavior to support customization through DragEventArgs.Effects.
  • Updated drag-and-drop to scroll horizontally when the drop caret is near the edges of the control.
  • Updated drag-and-drop to remove possible unnecessary scrolling following a drop.
  • Updated feedback when dragging to only show the 'Copy' or 'Move' indicator over valid drop locations.
  • Updated Single-Line Mode QuickStart to include a formula example with alternate style for nested parenthesis.
  • Updated IDataStore.GetText method to support String data format if UnicodeText and Text are undefined.
  • Updated IDataStore.SetText method to replace Html and Rtf data formats with new text.
  • Updated TagAggregatorBase<T> so it no longer calls Dispose when detaching from taggers which implement IDisposable. Taggers can use the new ITaggerBase.NotifyTagAggregatorDetached method to determine the most appropriate time to dispose of the tagger.
  • Updated SyntaxEditor.IsDocumentReadOnly to a read-write property and the corresponding dependency property SyntaxEditor.IsDocumentReadOnlyProperty now supports two-way bindings.
  • Updated the SyntaxEditor.SuspendCaretBlinking and ResumeCaretBlinking methods to support caret display when focus is not in the editor.
  • Updated the IntelliPrompt repositioning logic to better handle when a session is closed due to being scrolled out of view.
  • Updated the MoveSelectedLinesDownAction logic to prevent unexpected results when at the document end.
  • Updated outlining logic to ensure that a collapsed outlining node expands if its end is removed and it becomes an open node.
  • Fixed an issue where automatic vertical scrolling caused by dragging near the edge of a view might reset the selected text.
  • Fixed an issue that prevented dropping text around block selections.
  • Fixed an issue that caused the caret to stop rendering properly after dragging and dropping text outside of the editor.
  • Fixed a bug where setting HighlightingStyle.BorderColor to null in styles with a border could trigger an exception when rendering.
  • Fixed a bug where a code snippet with an $end$ defined immediately after a field may not position the caret properly when Enter was pressed after editing the field.
  • Fixed a bug where exported RTF and HTML didn't account for a customized plain text foreground.
  • Fixed a bug where calling IEditorView.InsertSurroundingText from witin a SyntaxEditor.DocumentTextChanged event handler could result in an incorrect final selection.
  • Fixed a bug where typing in a block selection after a collapsed outlining node could lead to an incorrect selection range.
  • Fixed a bug where a collapsed region without a related intra-text spacer at document end could throw an exception.
  • Fixed a bug where the selection wasn't always correct after an indent for a block selection that included virtual space.
  • Fixed a bug where a block selection that begins with no characters selected in the first line wouldn't copy the text properly.
  • Fixed a bug where pressing Enter with a block selection at the document end could incorrectly delete characters.
  • Fixed a bug where deleting a collapsed outlining node that had its quick info open could throw an exception.
.NET Languages Add-on
  • Added a Go To Definition QuickStart to demonstrate using an IResolver to navigate to the source of a reference.
  • Updated the C# parser grammar to support C# 8.0 syntax.
  • Updated the C# outliner to create outlining nodes for code-level constructs such as block statements. This feature can be disabled by setting the CSharpOutliner.CanOutlineCodeLevelConstructs property to false.
  • Updated the SourceFileLocation property to be populated on all ITypeMemberDefinition objects from source, and added it to IParameterDefinition and IVariableDefinition objects loaded from source. This allows for Go To Definition functionality to be implemented for all kinds of resolved objects.
  • Updated the DocumentationProvider.ToString method to return the raw XML documentation comment text.
  • Updated CSharpContextFactory and VBContextFactory to better handle target expression resolution when positioned immediately after a significant token.

  • Updated the parser grammar to support Python v3.9.5 syntax.
  • Updated the resolver to support namespace packages.
  • Removed support for Python v2.x syntax, which is well past end of life.
  • Fixed an issue where an aliased dotted import name might not resolve correctly.

Themes

  • Added WindowChrome support for the snap layout menu when hovering over the maximize button on Windows 11 systems.
