A new maintenance release of the Universal Windows Controls is now available.

Detailed Update List


  • Added the PieSeries.SliceToolTipFormat, SliceToolTipFunc, ChildSliceToolTipFormat, and ChildSliceToolTipFunc properties, which can be used to supply pie slice tooltips.
  • Updated stacked charts to show each data point's actual value in the label instead of the stacked value.
  • Fixed a rendering bug when plotting charts for a single date/time axis unit range.


  • Added UIA peers for the standard switcher and its items.
  • Added a virtual DockSite.ProcessDockHostKeyDown method that is called when a key is pressed while focus is within a DockHost.
  • Updated the workspace's layout logic to account for contained docking window minimum and maximum sizes.
  • Updated floating dock hosts without MDI to use the minimum size of the docked tool windows.
  • Updated layout serialization to save breadcrumb creation times.
  • Updated AdvancedTabControl to ensure the selected tab remains visible in tab overflow scenarios when the control is resized smaller.
  • Improved the can-execute logic for the DockingWindow.FloatCommand.
  • Improved the tracking of breadcrumbs for floating windows.
  • Fixed a bug where the AdvancedTabControl highlight brushes might not be updated correctly in a certain scenario.


  • Added the ColorEditBox.IsInitialValueComparedOnPopup property that determines whether the initial value is compared to the current value on the picker popup.
  • Added the ColorPicker.ComparisonValue and IsComparisonValueVisible properties that support a comparison color.
  • Added the HsbColorPicker.ComparisonValue and IsComparisonValueVisible properties that support a comparison color.
  • Improved DoubleEditBox and SingleEditBox to better support very small numbers.
  • Improved DoublePicker and SinglePicker to better support very small numbers.
  • Improved MaskedTextBox input logic to allow typing anywhere in the leading prompt characters.
  • Updated GradientStopSlider to return a default width when measured with infinite width.
  • Fixed a MaskedTextBox bug where pressing Backspace after the first character might not delete it.
  • Updated the UIA peers for edit boxes.
  • Fixed a bug introduced in a previous build where the MonthCalendar's decade view could throw an exception.
  • Fixed several MonthCalendar scenarios where non-Gregorian calendars could throw an exception.


  • Added the TreeListViewColumn.CellVerticalAlignment property, which defaults to Center and allows for configuring how content in the column's cells aligns vertically.
  • Updated TreeListBox to recursively search the tree for filter results as appropriate when the TreeItemChildrenQueryMode.OnExpansion option is used and TreeListBox.AutoExpandItemsOnFilter is set. In lazy-load scenarios where there are large load times (e.g. database or file system access), keep the AutoExpandItemsOnFilter property false when filtering to prevent initial display performance.
  • Improved the performance of handling some external updates to collections being edited inline.
  • Fixed a bug where updating a collection being edited inline by PropertyGrid wouldn't properly dispose removed property models.
  • Fixed a bug where new collection items in PropertyGrid might not appear read-only when the PropertyGrid.IsReadOnly property is set to true.

Micro Charts

  • Fixed a bug where passing integer values instead of doubles to a MicroWinLossSeries.ItemsSource could throw an exception.


  • Updated CompletionSession so that when auto-completing without the popup showing, it raises the Opened event in addition to the Closed event that was already raised.
  • Added the IServiceLocator.SyncRoot property, and updated SyntaxLanguage to be thread-safe for registering and unregistering services.
  • Fixed a bug with code snippet template session selection adjustment in a certain scenario.
.NET Languages Add-on
  • Improved lock access to the assembly repository across multiple threads.
Python Language Add-on
  • Fixed an outlining bug that could occur with elif statements.
