Hi Raymond,

Try the following approach to achieve the functionality.

ASPX:

    
            <telerik:RadPanelBar ID="RadPanelBar1" OnClientItemClicking="OnClientItemClicking" OnClientItemExpand="OnClientItemExpand" 
        
             runat="server" OnItemClick="RadPanelBar1_ItemClick"> 
        
            </telerik:RadPanelBar>

JavaScript:

    
            <script type="text/javascript"> 
        
            function OnClientItemExpand() 
        
            { 
        
                __doPostBack('<%= RadPanelBar1.ClientID %>'  , ''); 
        
            } 
        
            function OnClientItemClicking(sender, args) 
        
            { 
        
                if(args.get_item().get_expanded()) 
        
                { 
        
                    args.set_cancel(true); 
        
                    args.get_item().set_expanded(false); 
        
                } 
        
            } 
        
            </script>
