I'm basically trying to get this to work:

But in a Master/content page situation with ajax settings and with handlers for OnResponseEnd and OnRequestStart.

I must be missing something really obvious, but I can't for the life of me get this to work.  I'm going to paste my code, BUT -- can you all PLEASE post those files to the blog post that are supposed to work?  I have a hard time understanding why this doesn't work when I feel like I've followed all the instructions...

Aspx - Master
    <form id="form1" runat="server">
        <asp:PlaceHolder ID="phValid" runat="server">
<telerik:RadScriptManager ID="rsm" runat="server">  
               <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
               <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
               <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
<div class="pnlCourseMainContentDialog">
        <asp:ContentPlaceHolder id="cphMain" runat="server">

Aspx - Content
<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">
    <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
        <script type="text/javascript">
            window.$ = $telerik.$;
            function get_RadWindow() { var oWindow = null; if (window.radWindow) { oWindow = window.radWindow; } else if ((window.frameElement) && (window.frameElement.radWindow)) { oWindow = window.frameElement.radWindow; } return oWindow; }
            function JustClose() { get_RadWindow().Close(); }
            function fileUploaded(sender, eventArgs) {
                $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest();
            function requestStart(sender, eventArgs) {
            function responseEnd(sender, eventArgs) {
                var oWnd = get_RadWindow();
                var oArg = new Object();
       = $("#<%= hfId.ClientID %>").val();
                alert('Id is: ' + + " ");
                //Close the RadWindow and send the argument to the parent page
                if (oWnd)
            function test() {
                $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest();
    <asp:HiddenField ID="hfId" runat="server" />
    <asp:TextBox ID="tbId" runat="server"></asp:TextBox>
    <input type="button" onclick="test()" />

    protected void manager_AjaxRequest(object sender, Telerik.Web.UI.AjaxRequestEventArgs e)
        //handle the manager AjaxRequest event here
        hfId.Value = "100";
    protected void Page_Load(object sender, EventArgs e)
        RadAjaxManager manager = RadAjaxManager.GetCurrent(Page);
        manager.ClientEvents.OnRequestStart = "requestStart";
        manager.ClientEvents.OnResponseEnd = "responseEnd";
        manager.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(manager_AjaxRequest);
        manager.AjaxSettings.AddAjaxSetting(manager, this.hfId);

OH..  I just tried one more thing, I removed the PlaceHolder ID="phValid" and it works now.  I suppose somehow I have a bug in what I'm determining is valid.  Though I'll look dumb keeping this post up, maybe it'll help someone else with similar issues.

Apparently, in my Master Page, the Page_Init call is getting called in the lifecycle somewhere of the ajax call and in that case it's "invalid" by my code logic causing the content area to not be updated correctly...

No answers yet. Maybe you can help?
