This is the same feature as the "FilterRow" FilteringMode setting of RadGridView for WPF.

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>

Create a combo box control that supports multi selecting, like the WPF version e.g.

https://docs.telerik.com/devtools/wpf/controls/radcombobox/features/multiple-selection

This is the same feature as the TickOrigin in the WPF chart: https://docs.telerik.com/devtools/wpf/controls/radchartview/axes/axis

The property should specify where the ticks originate.

Hi Team,

Please implement this feature for WinUI =>

• Docs: WPF ChartView - SplineSeries - Telerik UI for WPF.
• Completed FR: ChartView: Ability to control the tension of the spline

If you'd like to see a real test project that demonstrates the problem, you can use the repro attached to my Forum post => Spline series are incorrectly drawn in UI for WinUI.

Thank you,

Sébastien
