Hi i am facing a very strange problem.

My requirement is to have a tree on the left hand side of a page a view on the right hand side of the page. Clicking various nodes of the tree shows different views.

I have implemented this using two rad pane groups. Now i have implemented all the logic and the tree nodes hide or show the desired RadPaneGroup, so i am going on the right path.

But the problem is that when the page initially loads both Pane Groups are shown. I want to have one initially hidden. The second RadPane Group visibility is collapsed but it still shows up. How do i hide one of the rad pane group initially.

Kind Regards,

    Telerik said :

    The RadPaneGroup control changes its
    Visibility property automatically when
    its visible panes vary. If you want to
    make a RadPaneGroup invisible you just
    need to make all its panes hidden (to
    set their IsHidden property to true).
    As the RadPaneGroup uses its
    Visibility property internally you
    shouldn’t change it yourself.

    RadPanelGroup and Visibility collapsed not working

    So you need to hide each of the RadPane in the RadPaneGroup to hide the RadPaneGroup :

    <telerik:RadPaneGroup Background="#F2F2F3" Name="redemptionBacthViewPaneGroup" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" telerik:ProportionalStackPanel.RelativeSize="400, 200" BackgroundVisibility="Collapsed">
    <telerik:RadPane IsHidden="True" Header="Assignment View" CanUserClose="False">
    </telerik:RadPane>
    <telerik:RadPane IsHidden="True" Header="Assignment View" CanUserClose="False">
    </telerik:RadPane>
</telerik:RadPaneGroup>

    You could also do code behind :

    myRadPaneGroup.HideAllPanes();
