                                </ItemTemplate>
                                <Items>

                                <CollapseAnimation Type="None"></CollapseAnimation>
                            </telerik:RadComboBox>

 <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
        <script type="text/javascript">
            function OnClientDropDownClosing(sender, args) {
                //            if (args.get_node().get_level() == 0)
                //            {
                //                args.set_cancel(true);
                //            }
                //            else {
                var item = sender.get_items().getItem(0); // Get the first RadComboBoxItem
                var treeView = item.findControl('tvDepartments'); // Find your RadTreeView
                var checkedNodes = treeView.get_checkedNodes(); // Retrieve the checked items in the RadTreeView

                var newText = '';
                checkedNodes.forEach(function (node) {  // Loop through the checked nodes. Requires jQuery!
                    if (newText != '') { newText += ', '; }
                    newText += node.get_text();
                });
                var comboBox = $find("<%= cbxDepartments.ClientID %>");
                comboBox.set_text(newText); // Set the RadComboBox text
                if ($.browser.msie) { // IE sometimes takes two tries for it to respond to new text
                    comboBox.set_text(newText);
                    //                }
                }
            }
        </script>

Hello,

I have tried to reproduce the issue but no avail. Here is the sample code I have tried.
JS:

function OnClientDropDownClosing(sender, args)
{
    var item = sender.get_items().getItem(0);
    var treeView = item.findControl('RadTreeView1');
    var checkedNodes = treeView.get_checkedNodes();
    var newText = '';
   checkedNodes.forEach(function (node)
    {
      if (newText != '')
         {
            newText += ', ';
         }
           newText += node.get_text();
   });
   var comboBox = $find("<%= RadComboBox1.ClientID %>");
 comboBox.set_text(newText);
 }

Thanks,
Princy.
