UI for WinUI

Release History

UI for WinUI 1.1.0

February 23, 2022

What's New

  • Introduced RadHeatMap control, which is used to visualize numeric data in a matrix-like representation along two axes. Its purpose is to present the data in colored rectangles where the color of each represents the rectangle's value and makes it quite easy to perceive and compare all values.


  • An exception ('XAML parsing failed.') is thrown when creating an unpackaged application in WinUI in Desktop.


  • Vertical scroll bar is covered by the sticky groups.
  • The height of the group panel differs for the available positions - should be consistent.
  • The last row is not visible when the IncrementalLoadingMode is Explicit and GroupPanelPosition is Top/TopInline.
  • There are binding errors in the output caused by the filter header of the control.
  • Filtering Flyout doesn't not respect theme changes while opened.


  • Flattened the default look of the Pushpin element of the control - the path data is now updated and its fill color, too.
  • The ClusterIcon resource is missing and leads to an exception.


  • Space key produces unexpected empty gaps in Numeric, DateTime, TimeSpan input and TextInput with controls in Desktop mode of WinUI.
  • In MaskedNumericInput, when AllowNullValue is True, setting value to null then typing 0 results in null value but it should be 0.00


  • The height of the control is 2px larger than other input controls for the Win32 version - all should be 32px by default.


  • Added support for Type 3 fonts.
  • Introduce support for digital signature for .NET Standard.
  • Provided API for setting different permissions when exporting encrypted PDF documents.
  • The measured size of the block inside the nested table is wrong.
  • A NullReferenceException is thrown when converting nested tables to PDF and the vertical alignment is set.
  • An ArgumentException is thrown when importing documents containing Font`s Widths array with entries defined as Indirect references.
  • An InvalidCastException is thrown when importing a not embedded TrueType Font.
  • UriFormatException is thrown when merging/cloning a document containing UriAction with an invalid URI.
  • Converting PNG to Jpeg processes only a part of the image on .NET 6.


  • NullReferenceException when importing a document that contains notes shapes with no row and column.
  • AnIndexOutOfRangeException is thrown when exporting a file in Russian culture under Windows 7 and the target platform is .NET Standard version.
  • Notes are not updated after inserting or removing cells.


  • PdfFormatProvider: A NullReferenceException is thrown when converting nested tables to PDF and the vertical alignment is set.
  • InvalidOperationException is thrown while importing DOCX file with nested content controls over the contents of a table cell with more than one paragraphs.
  • Importing empty content control that is the first element of a table cell leads to NullReferenceException.
