推荐答案

什么用的CommandName和CommandArgument已显示出的这个例子。这样，你可以只有一个处理程序。

What about using CommandName and CommandArgument has shown in this example. This way you can have just one handler.

<asp:Button id="Button1"
       Text="Sort Ascending"
       CommandName="Sort"
       CommandArgument="Ascending"
       OnCommand="CommandBtn_Click" 
       runat="server"/>

  <asp:Button id="Button2"
       Text="Sort Descending"
       CommandName="Sort"
       CommandArgument="Descending"
       OnCommand="CommandBtn_Click" 
       runat="server"/>
