Panel bar. Disable postback for items that have child nodes.

[Michael Finch]

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>
