Default sizing for RadSplitters

[Paul Brun]

So, I have a XAML block with the following:

(
<telerikDocking:RadDocking x:Name="ctlMainDocking" Grid.Row="2" HasDocumentHost="False" PreviewPin="ctlMainDocking_PreviewPin" PreviewShow="ctlMainDocking_PreviewShow" PaneStateChange="ctlMainDocking_PaneStateChange" >

            <telerikDocking:RadSplitContainer x:Name="ctlDetailContainer"  InitialPosition="DockedBottom" telerikDocking:ProportionalStackPanel.RelativeSize="0, 20">
                <telerikDocking:RadPaneGroup x:Name="ctlDetailGroup" VerticalContentAlignment="Top">
                </telerikDocking:RadPaneGroup>
            </telerikDocking:RadSplitContainer>

            <telerikDocking:RadSplitContainer x:Name="ctlContentContainer" InitialPosition="DockedRight" telerikDocking:ProportionalStackPanel.RelativeSize="0, 80" >
                <telerikDocking:RadPaneGroup x:Name="ctlContentGroup">
                </telerikDocking:RadPaneGroup>
            </telerikDocking:RadSplitContainer>

            <telerikDocking:RadSplitContainer x:Name="ctlNavigationContainer" InitialPosition="DockedLeft" telerikDocking:ProportionalStackPanel.RelativeSize="0, 20">
                <telerikDocking:RadPaneGroup x:Name="ctlNavigationGroup">
                </telerikDocking:RadPaneGroup>
            </telerikDocking:RadSplitContainer>
       
        </telerikDocking:RadDocking>
)

My question, how does the ProportionalStackPanel.RelativeSize actually work? I want to have the NavigationContainer fill up 20% of the screen by default and the ContentContainer 80%, but it seems to do the option and not sure how it should work or what the RelativeSize perimeters actually mean? Any insight would be helpful....

Thanks
Paul

Played around with this some more and got it all workin' the way I need it to work. I had to reorganize the XAML and two RAD groups into one......
