Problem with AJAX and User Controls

Question

Hi,
I am working with asp.net c#. While working with .aspx page the Ajax control(accordion) worked perfectly. But when i tried using it on Web user control .ascx the control didn't work. I hoping there is a work around this to make it work.
This is my source code for the control that is not working.

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="StartCourse1.ascx.cs" Inherits="LearningSource_Controls_StartCourse1" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %>
<style type="text/css">
    .style1
    {
        width: 110%;
    }
</style>
<ajaxToolkit:ToolkitScriptManager runat="server" ID="ScriptManager1" />
        <ajaxToolkit:Accordion ID="MyAccordion" runat="server" SelectedIndex="0"
                    HeaderCssClass="accordionHeader" HeaderSelectedCssClass="accordionHeaderSelected"
                    ContentCssClass="accordionContent" FadeTransitions="false" FramesPerSecond="40"
                    TransitionDuration="250" AutoSize="None" RequireOpenedPane="false" SuppressHeaderPostbacks="true">
                   <Panes>
                    <ajaxToolkit:AccordionPane ID="AccordionPane1" runat="server">
                        <Header><a href="" style="color:White">Simulation program</a></Header>
                        <Content>                       
                            Watch the
demonstration of the network simulation program named <span
 style="font-weight: bold;">Cisco Packet Tracer v3.2&nbsp; (do not use
the newer versions of the software in this module as they are much too
complex for our needs at this stage in the module).</span>&nbsp; <br>
                        </ajaxToolkit:AccordionPane></Panes></ajaxToolkit:Accordion>


Thanks for your help in advance. Regards
