Hi,

I am using the RadAjaxManager, but I keep getting this error as a YSOD. I got it once before and it was because I didn't have runat set to server on my form. But now I do. Here is my code:

<body>
    <form id="form1" runat="server">
      <telerik:RadAjaxManager ID="RadAjaxManager1" EnableAJAX="true" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">
        <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
        <UpdatedControls>
        <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
        </UpdatedControls>
        </telerik:AjaxSetting>
        </AjaxSettings>
        </telerik:RadAjaxManager>

    <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
    </telerik:RadScriptManager>

This seems correct to me. What am I missing?

Thanks
