    I have a PanelBar that is getting populated client-side via JS.  Below is a code example:

    var panel = $find('RadPanelBar');
    var rootItem = panel.findItemByText("RootItem");
    for (var i = 0; i < array.length; i++) {
        var item = new Telerik.Web.UI.RadPanelItem();
        item.set_text(array[i].someText);
        panel.trackChanges();
        rootItem.get_items().add(item);
        panel.commitChanges(); 
    }

    This seems to serve it's purpose, I can inspect the root item after the loop and can see all the added child items.  

    The problem is when I click on this RadPanelBar root item, nothing happens.  The "expand/collapse" icon switches on click and any expand/collapse/click events are fired as normal, just no child Items are shown.  I have tried almost everything.

    Even when adding the RadPanelItems statically at design time, I see the same problem.  
    <telerik:RadPanelBar ID="RadPanelBar1" runat="server" Width="100%" Height="600px">
        <Items>
            <telerik:RadPanelItem runat="server" Text="TestRoot" Expanded="True">
                <Items>
                    <telerik:RadPanelItem Text="TestChild">
                    </telerik:RadPanelItem>
                </Items>
            </telerik:RadPanelItem>
        </Items>      
    </telerik:RadPanelBar>

    This also has the same outcome, can't expand to see the child item.

    Any ideas?  Am I missing something?

    Hello Niko,

    I tested the issue that you describe but I could not get the described behavior. Here is a short video demonstrating how the control behaves from my side.

    Kind regards,
