The scrolling in RadChat feels incosistent and not smooth when having messages with different heights.
To work around this you can modify the ControlTemplate of ChatMessageList in order to set the Background property of the ScrollViewer element to a value different than null. For example, Transparent.
<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>
<!-- Other app resources here -->
<Style TargetType="chat:ChatMessageList" BasedOn="{StaticResource ChatMessageListStyle}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="chat:ChatMessageList">
<Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}">
<!--The background of the Scrollviewer is set here-->
<ScrollViewer x:Name="PART_ScrollViewer"
VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Disabled"
BorderThickness="0"
Background="Transparent">
<ItemsPresenter Margin="{TemplateBinding Padding}" />
</ScrollViewer>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>
</Application.Resources>

The list with the RadChat messages disappears when the ImageSource of ImageCardMessage is assigned after the control is loaded.
To work this around, you can pre-set the ImageSource of the image cards using a placeholder image.
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.

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>
