一個展開收合的ajaxToolkit:AccordionPane控件。Insus.NET在專案有用到它。 因為它可以節省顯示空間。不過有點不足，就是用戶剛開始使用，需要記得每個AccordionPane內容。或是需要使用一個顯而可見的名字。下面的演示中，只是兩個收合AccordionPane，如果多個的話，就會有上面提及的問題。

下面是HTML:ajaxToolkit:Accordion

復制代碼 代碼如下:

<ajaxToolkit:Accordion runat="server" SelectedIndex="-1" HeaderCssClass="accordionHeader"
                HeaderSelectedCssClass="accordionHeaderSelected" ContentCssClass="accordionContent"
                FadeTransitions="true" FramesPerSecond="5" TransitionDuration="250" AutoSize="None"
                RequireOpenedPane="false" SuppressHeaderPostbacks="true">
                <Panes>
                    <ajaxToolkit:AccordionPane runat="server">
                        <Header>
                            條件
                        Header>
                        <Content>
                           <Content>
                    ajaxToolkit:AccordionPane>
                    <ajaxToolkit:AccordionPane runat="server">
