    I need to get the equivalent to $find('<%=RadTreeView1.ClientID %>'); in JavaScript. The problem is my treeview is nested within a radpanelbar. Here is the code I have so far but it is not working.

                scheduler = $find('<%=RadScheduler1.ClientID %>');
                panelBar = $find('<%=RadPanelBar1.ClientID %>');
                item = panelBar.findItemByText("Events");
                treeview = item.findControl('<%=RadTreeView1.ClientID %>');

    Here is the aspx of the panel bar.
    <telerik:RadPanelBar ID="RadPanelBar1" runat="server" Skin="Web20" ExpandMode="SingleExpandedItem"
            AllowCollapseAllItems="false" Width="220px" BorderStyle="None" OnClientItemClicked="itemClicked"
                Height="500px">
                <CollapseAnimation Type="None" Duration="100"></CollapseAnimation>
                <Items>
                    <telerik:RadPanelItem runat="server" Text="Events" Font-Bold="true" Font-Size="Medium"
                        Expanded="true">
                        <Items>
                            <telerik:RadPanelItem runat="server">
                                <ItemTemplate>
                                    <telerik:RadTreeView ID="RadTreeView1" runat="server" Skin="Web20" CssClass="leftPanelContent"
                                        CheckBoxes="true" OnClientNodeChecking="OnClientNodeChecked" OnClientNodeClicking="OnClientNodeClicking">
                                    </telerik:RadTreeView>
                                </ItemTemplate>
                            </telerik:RadPanelItem>
                        </Items>
                    </telerik:RadPanelItem>

    Thanks,

    Hello,

    Actually the treeview is not in the template of the "Events" item, but in its first child's template, so the code should be like this:

    var panelBar = $find('<%=RadPanelBar1.ClientID %>'); 
    var item = panelBar.findItemByText("Events"); 
    var treeview = item.get_items().getItem(0).findControl("RadTreeView1"); 

    Kind regards,
