    I have radtreeview inside radcombobox.

     <telerik:RadComboBox ID="cbTreeViewSelect" runat="server"  ShowToggleImage="True" Skin="Metro" 
                        Style="vertical-align: middle;" OnClientDropDownOpened="OnClientDropDownOpenedHandler"
                        EmptyMessage="Choose a kit" ExpandAnimation-Type="None" CollapseAnimation-Type="None"
                        Font-Bold="true" AutoPostBack="true" Height="350px" CssClass="NormalText12Combo" OnTextChanged="cbTreeViewSelect_TextChanged">
                            <telerik:RadTreeView runat="server" ID="tvTree" OnClientNodeClicking="nodeClicking"
                                CssClass="NormalText12Combo" Width="100%" Height="340px" OnNodeClick="tv_NodeClick"
                                OnDataBound="tvTree_DataBound" />
                            <telerik:RadComboBoxItem Text="" />

    and scripts as described below.

    function nodeClicking(sender, args) {
            var comboBox = $find("<%=cbTreeViewSelect.ClientID %>");
            var node = args.get_node()

            var g = node.get_value();
            if (g == "0") {
            else {


                $("#<%=hidValue.ClientID %>").val(node.get_value());

            // Call comboBox.attachDropDown if:
            // 1) The RadComboBox is inside an AJAX panel.
            // 2) The RadTreeView has a server-side event handler for the NodeClick event, i.e. it initiates a postback when clicking on a Node.
            // Otherwise the AJAX postback becomes a normal postback regardless of the outer AJAX panel.


        function StopPropagation(e) {
            if (!e) {
                e = window.event;

            e.cancelBubble = true;

        function OnClientDropDownOpenedHandler(sender, eventArgs) {
            var tree = sender.get_items().getItem(0).findControl("tvTree");
            var selectedNode = tree.get_selectedNode();
            if (selectedNode) {

    In IE its working fine but in firefox when i click on hyperlink of top node of treeview it expands the tree but it hides(collapse) dropdown..

    i want to keep that treeview and dropdown expanded.

    Please help.

    Thanks in advance.
