The default behavior of the WinUI native Popup is to render within the bounds of its owner element. This means if the DataGrid reaches the end of the window and there is not enough space for the filtering control to draw, it will get clipped.
To avoid the clipping and allow the Popup to get displayed outside of the window, the ShouldConstrainToRootBounds property of the Popup should be set to false.
Add an API in the RadDataGrid control to allow setting the ShouldConstrainToRootBounds option of the Popup.
In the meantime, you can disable the Popup constrain via an implicit Style in App.xaml:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls" />
<ResourceDictionary Source="ms-appx:///Telerik.WinUI.Controls/Themes/Generic.xaml"/>
<!-- Other merged dictionaries here -->
</ResourceDictionary.MergedDictionaries>
<Style TargetType="Popup">
<Setter Property="ShouldConstrainToRootBounds" Value="False" />
</Style>
<!-- Other app resources here -->
</ResourceDictionary>
</Application.Resources>
Remove the space reserved for the sort indicator in the column header, when CanUserSort is False and therefore the sort indicator is not displayed. The current behavior prevents the user to easily center the header text.
To work this around, you can edit the ControlTemplate of DataGridColumnHeader. In the template, you can update the Visibility of the TextBlock with x:Name set to "SortIndicator" when CanUserSort is False.
Hi Support
I'm using RadDataGrid on several pages in my application. There a pages where the scrollbar does not appear. On some pages it works.
The structure of the pages is similar. What are your suggestions to look for.

The following exception is thrown when expanding row details with a height larger than the row height:
ArgumentOutOfRangeException: "Non-negative number required."
The group header row overlaps the column headers when scrolling to a column that is out of view upon previously resizing the window and the GroupHeaderDisplayMode is Frozen.
