一个展开收合的ajaxToolkit:AccordionPane控件。Insus.NET在专案有用到它。 因为它可以节省显示空间。不过有点不足，就是用户刚开始使用，需要记得每个AccordionPane内容。或是需要使用一个显而可见的名字。下面的演示中，只是两个收合AccordionPane，如果多个的话，就会有上面提及的问题。
下面是HTML:ajaxToolkit:Accordion
<ajaxToolkit:Accordion ID="Accordion1" runat="server" SelectedIndex="-1" HeaderCssClass="accordionHeader"
