aspnet ajax 1.0中的according控制項

在aspnet ajax 1.0的擴充包中，發現有個不錯的控制項according,其實意思就是摺疊控制項，比如一個頁有三個要顯示的部分，由於頁面
大小，要先示範某一部分，其他部分摺疊起來，（有點象OUTLOOK那個工具條的效果）。代碼很簡單，筆記之
 <ajaxToolkit:ToolkitScriptManager ID="ScriptManager1" runat="server" />
        <div>
            <ajaxToolkit:Accordion ID="Accordion1" runat="server" FadeTransitions="True" SelectedIndex="0" TransitionDuration="300"  HeaderCssClass="accordionHeader" ContentCssClass="accordionContent">
            <Panes>
                <ajaxToolkit:AccordionPane id="AccordionPane1" runat="server">
                <Header> AJAX PANE</Header>
                <Content>
          內容1

                </ajaxToolkit:AccordionPane>
                <ajaxToolkit:AccordionPane id="AccordionPane2" runat="server">
