Release History

Telerik UI for WPF 2025.2.707

July 7, 2025

Common

FIXED

ComboBox

FIXED
  • ArgumentOutOfRangeException on ItemsSource reset when AllowMultipleSelection is True.

DateRangePicker

FIXED
  • ArgumentOutOfRangeException is thrown when the Separator contains letters and Clear is executed.

GridView

FIXED
  • ArgumentOutOfRangeException when setting FrameworkElement with empty size (NaN or Zero) as DisplayContent of ColumnGroupDescriptor.
  • Cells are missing when scrolling a RadGridView with right frozen columns.
  • The control hangs when resized and frozen columns are enabled (Fluent theme).
  • The scrolling becomes very slow when setting the left and right frozen columns to 0 and resizing the columns so that their summary width is smaller than the data grid's width.
  • Missing types regarding GridViewColumns cause exceptions when saving.
Breaking Changes
  • Disallowed setting MinColumnWidth to 0. Only positive values are now allowed.

RibbonView

FIXED
  • The maximize icon in RibbonWindow did not update correctly when switching between maximized and normal window states in Office2019 and VisualStudio2019 themes. The icon now updates as expected.

FIXED
  • NullReferenceException when loading a document that contains DateProperties with no FullDateDescriptor.

ScheduleView

FIXED
  • Slowed performance due to try/catch of exceptions in scenarios with a recurring appointment with no end date for its recurrence.
