I want to have 2 panes, one larger than the other with a split vertically. I was these panes to be stretched to the size of their container, in this case a grid row. So I have this
<telerikDocking:RadDocking x:Name="radDocking" Grid.Row="2">
<telerikDocking:RadSplitContainer InitialPosition="DockedTop" Orientation="Horizontal" VerticalAlignment="Stretch">
<telerikDocking:RadPaneGroup telerikDocking:ProportionalStackPanel.RelativeSize="200, 200">
<telerikDocking:RadPane Header="pane" />
</telerikDocking:RadPaneGroup>
<telerikDocking:RadPaneGroup telerikDocking:ProportionalStackPanel.RelativeSize="400, 200">
<telerikDocking:RadPane Header="pane" />
</telerikDocking:RadPaneGroup>
</telerikDocking:RadSplitContainer>
</telerikDocking:RadDocking>
However, this doesn't stretch to the grid row height. How can I get this to happen?
Thanks
