Hello, I tried to implement the sample application from your docs. (https://docs.telerik.com/devtools/winui/controls/raddatagrid/row-details)
But it seems to be not working, the detail area is not displayed completely. Only one column.
I have a similar behavior on another application.
Details:
- .NET 7
- Windows 11 Pro Version 23H2 (22631.3155)
- Telerik WinUI 2.9.0
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>
The field filters in the DataGridNumericalFilterControl of DataGridNumericalColumn are using RadNumericBox controls for the input visuals. By default RadNumericBox is limited to values between 0 and 100, which means you cannot enter values outside of this range.
To work this around, you can re-template the DataGridNumericalFilterControl in order to set the Minimum and Maximum properties of the RadNumericBox element to NaN.

Dynamically changing the Header of a RadDataGrid column is clearing the header visual's content. This means that you no longer see the header. To reproduce this the SizeMode of the column should be set to Fixed.
To work this around, instead of changing the Header of the column, you can assign the Header initially to a visual element - like TextBox - and change its content (like the Text property). Or alternatively, avoid the Fixed SizeMode.
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.
Add a setting on the column level to control the case sensitivity more easily.
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.

Allow changing the displayed value. This could be done by introducing a new property for the DataGrid columns (something like DistinctValuesDisplayPath).
Adding new Liverpool instances does not change the UI but it should - multiple Liverpool instances should be present in the rows.
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.
