RadControls for ASP.NET AJAX

To find a RadTreeView client-side instance when embedded in another control, use server side functionality to locate the RadTreeView ClientID. In the following example the RadTreeView is embedded in a RadMenu item template.

CopyASPX
<telerik:RadMenu ID="RadMenu1" runat="server">
    <ItemTemplate>
        <telerik:RadTreeView ID="RadTreeView1" runat="server">
        </telerik:RadTreeView>
    </ItemTemplate>
</telerik:RadMenu>
CopyJavaScript
<script type="text/javascript">
    var tree = $find('<%=RadMenu1.Items[0].FindControl("RadTreeView1").ClientID %>');  
</script>
