OK, here's a simplified example for my problem (I called the file "PanelBar_SelectedItemDemo.aspx"):

    
            <%@ Page Language="C#" AutoEventWireup="true" Theme="" %> 
        
            <%@ Register TagPrefix="radp" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %> 
        
            <script runat="server">  
        
                protected void Page_Load(object sender, EventArgs e)  
        
                {  
        
                    NavigationPanel.LoadContentFile("Navigation.xml");  
        
                    try  
        
                    {  
        
                        Output.Text = NavigationPanel.SelectedItem.ToString();  
        
                    }  
        
                    catch  
        
                    {  
        
                        Output.Text = "NO SELECTED ITEM!";  
        
                    }  
        
                }  
        
            </script> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <html xmlns="http://www.w3.org/1999/xhtml" > 
        
            <head runat="server">  
        
                <title>Untitled Page</title> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server">  
        
                    <asp:ScriptManager ID="ScriptManager1" runat="server" /> 
        
                    <radctrl:RadPanelbar ID="NavigationPanel" runat="server" PersistStateInCookie="True" Skin="Outlook"></radctrl:RadPanelbar> 
        
                    Output: <asp:Label ID="Output" runat="server"></asp:Label> 
        
                </form> 
        
            </body> 
        
            </html>

And file "Navigation.xml" contains this:

    
            <?xml version="1.0" encoding= "utf-8" ?> 
        
            <PanelBar> 
        
                <Item Text="RadEditor" Postback="true" NavigateUrl="PanelBar_SelectedItemDemo.aspx" /> 
        
                <Item Text="RadPanelBar" Postback="true" NavigateUrl="PanelBar_SelectedItemDemo.aspx"  /> 
        
                <Item Text="RadMenu" Postback="true" NavigateUrl="PanelBar_SelectedItemDemo.aspx"  /> 
        
                <Item Text="RadTabStrip" Postback="true" NavigateUrl="PanelBar_SelectedItemDemo.aspx"  /> 
        
            </PanelBar>

Expected behaviour:
Label "Output" should show the currently selected panelbar item. If no item is selected, output should be "NO SELECTED ITEM!".

Result:
Output is always "NO SELECTED ITEM!", even if an item is selected!

Question:
What am I doing wrong??

Hi ,

I suspect that the reason for the problem is that you did not mark anyone of the items of the xml file with Selected=True property.

Please see the attached projet which works as expected. If this does not help you, could you please modify it so the problem to appear and send us back to us to test it locally?
