Accordion响应鼠标单击事件

我使用数据绑定方式，希望鼠标单击每个Header时在页面的右边显示不同的信息？
<cc1:Accordion ID="MyAccordion" runat="Server" SelectedIndex="0" HeaderCssClass="accordionHeader"
  HeaderSelectedCssClass="accordionHeaderSelected" ContentCssClass="accordionContent"
  AutoSize="None" FadeTransitions="true" TransitionDuration="250" FramesPerSecond="40"
  RequireOpenedPane="false" SuppressHeaderPostbacks="true" 
  onitemcommand="MyAccordion_ItemCommand">
  <Panes>  
  </Panes>
  <HeaderTemplate>
  <asp:HyperLink ID="HyperLink1" runat="server" Text='<%# Eval("lxname") %>'></asp:HyperLink>
  </HeaderTemplate>
  <ContentTemplate>
   
  <%# Eval("lxms") %>
   
  </ContentTemplate>
  </cc1:Accordion>

<asp:HyperLink ID="HyperLink1" runat="server" Text='<%# Eval("lxname") onclientclick="ShowMessage();return false;" %>'></asp:HyperLink>
