  Hi
  I am have a combo with a treeview in it, i need to find the selected node and i am able to do this in aspx page, but the same function fails in .ascx page.
  The below is the function which i am calling in client side.
  
  

  function

   

  radPricingLevelTree_ClientNodeClicked(sender, eventArgs)

   

  {

   

  var node = eventArgs.get_node();

   

   

  var comboBox = $find("<%= radPricingLevelCombo.ClientID %>");

   

   

  comboBox.set_text(node.get_text());

  comboBox.trackChanges();

  comboBox.get_items().getItem(0).set_value(node.get_text());

  comboBox.commitChanges();

  comboBox.hideDropDown();

  }
  Pls help

  Hi Qaja Mohiddin,
  
  You need to find the proper id of the combobox like this:
  
  

  function radPricingLevelTree_ClientNodeClicked(sender, eventArgs)

  {

  ...

  var comboID = sender.get_id().replace("_i0_radPricingLevelTree", "");

  var comboBox = $find(comboID);

  ....

  }

  
  
  Best wishes,

  I am doing the same, but in a different manner.
  
  I am using the radsplitter expand/collapse.
  
  The problem is in one Radpane the radgrid is fixed & paged so when we collpase the bottom RadPane there is a void.
  I want to change the attributes of the radGrid to show more rows to fill in the void as well as return it back when the splitter is expanded halfway up the page.
  
  I'm using the collapse/expand event of the radpane to trigger the function that will change the events.
  Right now the only thing I get is [object].  if I add tagname to it is says "Div"
  
  This is while using <%=control.clientid=>  which I will include here.
  
  The example above is okay if the sender is what you are looking for, but I'm looking for a different control where we would normally use getelementid().
  
  
  Thanks
  
  
  This is the test code for me to bring back the id of the control.
  
  
  

  <

   

  script language="javascript" type="text/javascript">
      function RadPaneCollapsed() {
          var dnetGrid;dnetGrid = document.getElementById('<%=grdcontrol.ClientID%>');
          if (dnetGrid != null) {
          alert(dnetGrid.tagName);
      }
      else {
          alert("No ID");
      }
  }
  </script>

  function LoadInstitutionList(sender, eventArgs) {

                 var item = eventArgs.get_item();

                 var CboTerm = $find("<%= RadCbocountry.ClientID %>");

                 CboTerm.set_text("loading.........");

                 if (item.get_index() >= 0) {

                     CboTerm.requestItems(item.get_value(), false);

                 }

                 else {

                     CboTerm.set_text(" ");

                     CboTerm.clearItems();

                 }
