Hi Jincy,

I suggest to check the level of the clicked node in OnClientNodeClicking event handler like this:

 function nodeClicking(sender, args)  
 {  
   var comboBox = $find("<%= RadComboBox1.ClientID %>");  
   var node = args.get_node()  
   if(node.get_level() != "0")  
   {  
     comboBox.set_text(node.get_text());  
     comboBox.trackChanges();  
     comboBox.get_items().getItem(0).set_value(node.get_text());  
     comboBox.commitChanges();  
     comboBox.hideDropDown();  
   }  
 }  
 

Hope this helps.
