    I have a RadPanelBar, which includes several panelitems.  I put a radtreeview under each of the item. then add the first-level treenodes to them programmatically, and the node Expandmode has been set to "ServerSideCallBack" so that the second level node can be expanded on demand.

    The program works ok but the only issue is the Scrollbar does not appear automartcally when I expanded the treenode and the content exceed the height. But if I set the Expand="True" and "Selected="true" at the panelitem then the scrollbar appear. But logically only one can be expanded and selected, how to fix this?

    I am using the latest build (2012.3.1205.35) and tried on IE 9/Google Chrome, same result

    <telerik:RadPanelBar ID="panelBarMain" runat="server" Width="100%"
    Height="100%" ExpandMode="FullExpandedItem"
    Value="Trackings" Text="Trackings"
    Value="Tenders" Text="Tenders" Visible="false" Expanded="true"

    Hello, Andy.

    The issue is partially related to a change in the tree view and the panel bar behaviour. In particular it's related to relative content in scrollable container.

    For now the quickest solution is to use the following snippet:

    .RadPanelBar .rpGroup {
        position: relative;

    On the long term, this snippet will be incorporated in the base stylesheets of the PanelBar and will be included with future releases. We are also looking into the tree view part and we'll fix that too.
