November 10, 2021

ColorEditor

NEW

ComboBox

NEW
  • Introduced DropDownButtonIconContent and DropDownButtonIconTemplate properties to allow for easier customization of the drop-down icon.

DataForm

FIXED
  • Empty space remains at the top of the DataForm when CommandButtonsVisibility is set to None in the Office2013 theme.

Diagrams

FIXED
  • TextShape with background and no Text created by TextTool cannot be selected or deleted.
  • Expanding the top parent of nested containers leads to rendering the last sub-container, even though its parent is collapsed.

Docking

FIXED
  • Order of split containers and groups in the saved XML is wrong.

GanttView

NEW
  • New property AutoSizeTimeline allows users to set the timeline part to automatically take all the available space.

GridView

NEW
  • Improved support for ICustomTypeProvider objects when using nested properties and indexers, e.g. Player.Name, Clubs[0].Players[GK].Name.
FIXED
  • An exception is thrown when using VirtualQueryableCollectionView with Entity Framework and grouping operations.
  • When selecting all items, grouping and then filtering, the SelectedItems collection is not updated correctly.
  • Two Tabs are needed to focus either the filter text box or its successive match case button in the FilteringControl.

ListBox

FIXED

NumericUpDown

FIXED
  • Entering a large value followed by a letter freezes the application.
  • Up and down buttons stayed pressed when touch is executed in a Popup that is positioned outside of the host Window.

RichTextBox

FIXED
  • InsertHyperlinkDialog adds automatically http:// in front of any link not containing http/https.
  • Moving the keyboard focus around RichTextBox raises new GotFocus/LostFocus events despite the fact that the control is already focused.
  • An InvalidOperationException is thrown during the layout of a table cell with a floating image.
  • A KeyNotFoundException is thrown when loading an RTF file with missing fonts.
  • Setting IsPrimary at run-time does not affect the visibility of styles.

FIXED
  • All day appointments in agenda view will now display the text All day when the appointment is marked as having a whole day duration.
  • When you set ShowWeekGroupHeaders to WeekViewDefinition, a double border appears in Office Black/Blue/Silver, Summer, Vista, Transparent, Expression Dark.

SpreadProcessing

FIXED
