In the TreeView control it is possible to disable postbacks on nodes that have children but still allow these nodes to be expanded. This is achieved as follows:

// server side
RadTreeView1.OnClientNodeClicking = "ClientNodeClicking";

//client side
function ClientNodeClicking(sender, eventArgs)
{
 var node = eventArgs.get_node();
 if(node.get_nodes().get_count() > 0)
 {
  eventArgs.set_cancel(true);
 }
}

Is it possible to achieve the same thing with the panelBar control?

Hello Michael ,

You can do this by two ways:

1.Just set the PostBack property of these items to False.
2
.Hook on the OnClientItemClicking event and execute the following code:
<script type="text/javascript">  
    function OnClientItemClicking(sender,e)  
    {  
        var item = e.get_item();   
         if(item.get_items().get_count() > 0)   
         {   
           e.set_cancel(true);   
           if(!item.get_expanded())  
           {  
             item.expand();  
           }  
           else  
           {  
             item.collapse();  
           }  
         }   
    }  
    </script>
