Hi,

On the video, you see the WinUI and UWP versions of the same implementation. I use expando to set the ItemsSource.

Differences:
1- Header has a mouse over state on WinUI. What is the trick to not have this?

2- In my DescriptionControl.xaml, the control has an hard coded value of Height=192. WinUI grid ignores this value. However, setting the RowHeight in the RadDataGrid does the job. Is it a bug/regression/new expectation?

3- For each timestamp (TimestampColumn), the SizeMode is Auto. In WinUI, my columns are much larger than UWP version.

4- Surely super easy, how to change the foreground and background color of the header column? Background and Foreground don't exist on DataGridTypedColumn. The default output of UWP is nicer.

Thank you!

Telerik WinUI 2.X -- VS Extensions for 2022

I was noticing that there is not a VS Extensions for 2022 for the product set WinUI 2.X in my Progress folders. And I'm not sure what this means.

As you can see I have the templates for WinUI. What am I missing?

Sincerely,
Keith Nicholson

[RadDataGrid] Crash at startup with or without ItemsSource

Hi,

Load the sample app, it generates: Error HRESULT E_FAIL has been returned from a call to a COM component.

I have the same in a UWP app and it works perfectly.

<grid:RadDataGrid
x:Name="DataGrid"
Grid.Row="1"
AutoGenerateColumns="True"
Background="#f0f0f0"
BorderThickness="0"
FrozenColumnCount="4"
GridLinesThickness="1"
GridLinesVisibility="Horizontal"
Margin="0,16,0,0"
SelectionMode="None"
UserColumnReorderMode="None"
UserFilterMode="Disabled"
UserGroupMode="Disabled">
<grid:RadDataGrid.Commands>
<powerNumbers:PowerNumbersAutoGenerateCommand />
</grid:RadDataGrid.Commands>
</grid:RadDataGrid>

TabControls fails in Window

This works:

<Window
    x:Class="xxxxxx"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:telerik="using:Telerik.UI.Xaml.Controls" 
    mc:Ignorable="d">
    <Grid>
        <TabView>
            <TabView.TabItems>
                <TabViewItem Header="CMD Prompt"/>
                <TabViewItem Header="PowerShell"/>
                <TabViewItem Header="Windows Subsystem for Linux"/>
            </TabView.TabItems>
        </TabView>
    </Grid>
</Window>

This does not due to the following. Using all of the latest nuget packages (2.0). I suspect it is related to being in a Window vs a control:

Microsoft.UI.Xaml.Markup.XamlParseException
HResult=0x802B000A
Message=XAML parsing failed.

                <telerik:RadTabItem Header="Tab 4" Content="The content of tab item 4"/>
            </telerik:RadTabControl.Items>
        </telerik:RadTabControl>
    </Grid>
</Window>
