Node text returns null until clicked

[Joe Burton]

I'm using the selected nodes in a treeview to populate a simple breadcrumb in my tab strip on the client side.  If I haven't clicked on the parent node first then it will return null.  Here is the code that is driving the functionality.  Any help would be greatly appreciated...

        function OnClientNodeClicked(sender, args)
        {
            var treeView = $find("<%= RadTreeView1.ClientID %>");
            var tabStrip = $find("<%= RadTabStrip1.ClientID %>");
            var selectedTab = tabStrip.get_selectedTab();
            var selectedNode = treeView.get_selectedNode();
            var parentNode = selectedNode.get_parent();
            if (selectedNode.get_level() == 0)
            {
                selectedTab.set_text(selectedNode._text);
            } else {
                selectedTab.set_text(parentNode._text + " -> " + selectedNode._text);
            }
        }

Hi Joe,

Give a try with following client side code in order to show the breadcrumb for RadTreeView.

JavaScript:

 function onMouseOver(sender, args)
 {
       var node = args.get_node();
       var s = node.get_text();
       var currentObject = node.get_parent();
       while (currentObject != null)
       {
         // get_parent() will return null when we reach the treeview
         if (currentObject.get_parent() != null)
         {
           s = currentObject.get_text() + " > " + s;
         }
         currentObject = currentObject.get_parent();
       }
        // Here s contains th path
        // Your code to for setting the tabstrip text
   }

Thanks,
Princy.

That did the trick...I put the code in my OnClientNodeClicked event.  Posting the final version that works like a charm.  Thanks...

       function OnClientNodeClicked(sender, args)
       {
        var node = args.get_node();
        var s = node.get_text();
        var currentObject = node.get_parent();
        while (currentObject != null)
        {
            // get_parent() will return null when we reach the treeview
            if (currentObject.get_parent() != null)
            {
            s = currentObject.get_text() + " > " + s;
            }
            currentObject = currentObject.get_parent();
        }
        var tabStrip = $find("<%= RadTabStrip1.ClientID %>");
        var selectedTab = tabStrip.get_selectedTab();
        selectedTab.set_text(s)
       }
