我得到了答案，但是。它仅适用于 IE。它不适用于 Firefox。您的评论很荣幸。

可能是浏览器的问题。尝试使用其他浏览器。

我认为您的代码不完整。如果你想实现可折叠面板......你必须使用两个面板，一个用于标题，另一个用于内容。最后在 Collapsible Panel Extender 中设置如下选项。

 <Ajax:CollapsiblePanelExtender ID="CollapsiblePanelext1" runat="server"   CollapseControlID="pnl1Head" Collapsed="true" ExpandControlID="pnl1Head" TextLabelID="lblMessage" CollapsedText="Show" ExpandedText="Hide" ImageControlID="imgArrows" ExpandDirection="Vertical" TargetControlID="pnl2Content" ScrollContents="True" ExpandedImage="../images/collapse_blue.jpg" CollapsedImage="../images/expand_blue.jpg"> </Ajax:CollapsiblePanelExtender>
