    Hi Team

    I have a RadTreeView and RadListBox.
    Based on RadTreeview selection I need to load the RadListBox.  My problem is if I select any node from RadTreeview RadAjaxLoadingPanel is not dispaying and RadListBox is not populating with binded values.

    Please help me to do this scenario. Please find the code here.

     <AjaxSettings>  
            <telerik:AjaxSetting AjaxControlID="RadAjaxManager1" >          
                <UpdatedControls>
                   <telerik:AjaxUpdatedControl ControlID="RadTreeView1" LoadingPanelID="RadAjaxLoadingPanel" />
                   <telerik:AjaxUpdatedControl ControlID="RadListBox_Vehicles"  LoadingPanelID="RadAjaxLoadingPanel" />
              </UpdatedControls>
            </telerik:AjaxSetting>
       </AjaxSettings>


     protected void RadTreeView1_NodeClick(object sender, RadTreeNodeEventArgs e)
        {
            String selectedNode = e.Node.Value;
            PopulateListBox(selectedNode);
      }

    My requirement is I need to show the refreshed listbox value on selection of Treeview node.

    Thanks in advance

    Hi Sharan,

    Please ensure that you have Skin property set ion the RadAjaxLoadingPanel declaration. Also please set UpdatePanelsHeight property of the RadAjaxManager to "100%" and verify how it goes.
