I am getting the error:

Script control '' is not a registered script control.
Script controls must be registered using RegisterScriptControl() before
calling RegisterScriptDescriptors().
Parameter name: scriptControl

with the following code:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Test_Default2" %>

<!DOCTYPE html>

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

<head runat="server">

<title></title>

</head>

<body>

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

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

<telerik:RadAjaxManager runat="server" ID="ramRoot" Visible="false">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="Timer1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="pMessage" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="pMessage">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="pMessage" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="btnClose">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="pMessage" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<asp:HiddenField runat="server" ID="hfMessageHidden" Value="0" />

<asp:Timer ID="Timer1" runat="server" Interval="10000" OnTick="Timer1_Tick" Enabled="true"></asp:Timer>

<asp:Panel runat="server" ID="pMessage" CssClass="pageMessagePanel">

<asp:LinkButton runat="server" ID="btnClose" class="close" data-dismiss="alert" aria-hidden="true" Text="x" />

<asp:Label runat="server" ID="lMessage">

</asp:Label>

</asp:Panel>

<div>

<p>Hello</p>

</div>

</form>

The codebehind methods have their contents commented out, so really what you see here is what you get. When I remove the <asp:Panel tag, the error goes away. But I want the <asp:Panel tag. Anyone have any idea what might be going on?

Thanks!
