小弟我刚刚学习Ajax技术，今天随便做了个界面，是用AjaxControlToolKit中的Accordion，是折叠的，但是当我点击Pane的头部时，就刷新了而且页面就一片空白。不知道是什么原因？请各位帮忙看看。
现贴代码如下：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Accordion.aspx.cs" Inherits="Accordion" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="AjaxToolKit" %>
<%@ Register Assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
Namespace="System.Web.UI" TagPrefix="asp" %>

<ajaxToolkit:Accordion ID="MyAccordion" runat="server" SelectedIndex="0"

<Panes>
<ajaxToolkit:AccordionPane ID="AccordionPane1" runat="server">
<Header><a href="" class="accordionLink">1. Accordion</a></Header>
<Content>
The Accordion is a web control that allows you to provide multiple panes and display them one at a time.
It is like having several <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="" Text="CollapsiblePanels" />
where only one can be expanded at a time. The Accordion is implemented as a web control that contains
AccordionPane web controls. Each AccordionPane control has a template for its Header and its Content.
We keep track of the selected pane so it stays visible across postbacks.

</ajaxToolkit:AccordionPane>
</Panes>
</ajaxToolkit:Accordion>

</form>

请各位尽量帮忙！！！谢谢。
