Hi,

Is there a working example of how to get the RadMenu to cause an ajax request that occurs when a user mouses over a menu item, pass that item text to the server, then use that name as a key to look up other items to populate another dependent RadMenu? I have tried this using the following code but was unsuccesful.

UserControl.ascx

<div id="CloudDropDown" class="clearfix">

    <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

        <script type="text/javascript">

            function ChangeSubMenu(s, e) {

                $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequestWithTarget("<%= mainMenu.UniqueID %>", e.get_selectedItem().get_text());

            }

        </script>

   </telerik:RadCodeBlock>





    <telerik:RadAjaxManagerProxy ID="ajaxManagerProxy" runat="server">

       <AjaxSettings>

           <telerik:AjaxSetting AjaxControlID="mainMenu">

               <UpdatedControls>

                    <telerik:AjaxUpdatedControl ControlID="subMenu" LoadingPanelID="radAjaxLoadingPanel" />

               </UpdatedControls>

           </telerik:AjaxSetting>

       </AjaxSettings>

    </telerik:RadAjaxManagerProxy>



    <telerik:RadMenu ID="mainMenu" runat="server" DataSourceID="SitemapDataSource1" Flow="Horizontal" OnClientMouseOver="ChangeSubMenu" MaxDataBindDepth="1" EnableEmbeddedSkins="false" Skin="MedpacRed">

    </telerik:RadMenu>



    <telerik:RadMenu ID="subMenu" runat="server" EnableEmbeddedSkins="false" Skin="MedpacRed" Visible="false">

    </telerik:RadMenu>



    <asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" ShowStartingNode="false" />

</div>

UserControl.ascx.cs

protected void Page_Load(object sender, EventArgs e)

    {

        RadAjaxManager manager = RadAjaxManager.GetCurrent(Page);



        manager.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(manager_AjaxRequest);





    }



    protected void manager_AjaxRequest(object sender, AjaxRequestEventArgs e)

    {

        Guid rootGui = Utility.FindPageGuid(e.Argument);

        List<SiteNavigationItem> items = Utility.ConvertCmsPages(Utility.FindChildren(e.Argument), rootGui);





        subMenu.DataSource = items;

        subMenu.DataTextField = "Text";

        subMenu.DataNavigateUrlField = "Url";

        subMenu.DataFieldID = "ID";

        subMenu.DataFieldParentID = "ParentID";

        subMenu.EnableEmbeddedSkins = false;

        subMenu.DataBind();

        subMenu.Visible = true;

    }

Here is my master page that houses my user control.

<%@ Master Language="C#" AutoEventWireup="true" CodeFile="Base.master.cs" Inherits="App_Master_Base" %>

                <div id="contentWrapper" class="clearfix">

                    

                    <div id="content" class="clearfix">

                            <asp:ContentPlaceHolder ID="baseContent" runat="server"/>

                        </div>



                        

                        <div id="footer">

                            <asp:ContentPlaceHolder ID="contentFooter" runat="server"/>

                        </div>

                        

                    </div>

                    

                </div>

            </div>

            

        </div>

    </form>

</body>

</html>

Can this be accomplished or am I doing something wrong?

Thanks for you help,
