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" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head id="Head1" runat="server">

<title></title>

<asp:ContentPlaceHolder id="head" runat="server">

</asp:ContentPlaceHolder>

</head>

<body class="outthere">

<form id="form1" runat="server">

<telerik:RadScriptManager ID="scriptManager" runat="server" />

<telerik:RadAjaxManager ID="ajaxManager" runat="server" />

<telerik:RadAjaxLoadingPanel ID="radAjaxLoadingPanel" runat="server" BackgroundPosition="Center" Skin="Default" />

<div id="pageWrapper">

<div id="page">

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

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

<div id="logo">

<img id="medpaclog" runat="server" src="~/App_Themes/MedpacRed/images/medpacLogo.gif" />

</div>

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

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

</div>

<div id="genericBanner">

<img id="Img1" runat="server" src="~/App_Themes/MedpacRed/images/PinTek_MedPak_WebsiteBanner.png" alt="banner" width="1000" />

</div>

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

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

<div id="baseMainContentWrapper">

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

</div>

<div id="footer">

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

</div>

</div>

</div>

</div>

</form>

</body>

</html>

Can this be accomplished or am I doing something wrong?

Thanks for you help,
Bobby
