Can anybody help with why the following will not display a vertical

<Grid>
        <telerik:RadListBox HorizontalAlignment="Left" Height="135" Margin="24,13,0,0" VerticalAlignment="Top" Width="510" ItemsSource="{Binding Source={StaticResource groups}, UpdateSourceTrigger=PropertyChanged}" SelectedIndex="{Binding AssocIdx, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}">
            <telerik:RadListBox.ItemTemplate>
                <DataTemplate>
                    <VirtualizingStackPanel>
                        <TextBlock Text="{Binding display}" />
                    </VirtualizingStackPanel>
                </DataTemplate>
            </telerik:RadListBox.ItemTemplate>
            <telerik:RadListBox.GroupStyle>
                <GroupStyle HeaderTemplate="{StaticResource groupTemplate}" />
            </telerik:RadListBox.GroupStyle>
        </telerik:RadListBox>
</Grid>

but the following does?

<Grid>
        <telerik:RadListBox Height="77" Width="410" ItemsSource="{Binding Source={StaticResource groups}}" SelectedIndex="{Binding AssocIdx, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}">
            <telerik:RadListBox.ItemTemplate>
                <DataTemplate>
                    <VirtualizingStackPanel>
                        <TextBlock Text="{Binding Name}" />
                    </VirtualizingStackPanel>
                </DataTemplate>
            </telerik:RadListBox.ItemTemplate>
             
            <telerik:RadListBox.GroupStyle>
                <GroupStyle HeaderTemplate="{StaticResource groupTemplate}" />
            </telerik:RadListBox.GroupStyle>
             
        </telerik:RadListBox>
    </Grid>

Hello Stephen,

As I've explained in the other forum post you've opened we will need more information on the explained behavior.

You can open a support ticket and attach a sample project demonstrating your approach which will help us in further assisting you.
