[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>

How to size row height for multiline data in datagrid

Is there a way to change the row height when the data for a column is multiline? Not every row has multiline so I don't want to use the RowHeight property. I can use a flyout to display the data, as in the attached screenshot, but I'd really rather have it directly in the grid. I'm using a textblock control inside a template column. I had it working in using the Community Toolkit datagrid but when I switched to the Telerik version, I haven't been able to figure it out.
