      // How to access the button, and do some work when it is clicked.
}

执行此操作的正确方法是将CommandName参数添加到Your按钮，然后在Your EventHandler中捕获它。示例如下：

<asp:Button ID="Btn_addFriend" runat="server"  Text="Add friend" CommandName="Add friend" />

现在您可以在事件处理程序中捕获此命令，如下所示：

protected void ListViewUsers_ItemCommand(object sender,ListViewCommandEventArgs e)
{
  if(String.Equals(e.CommandName, "Add friend"))
  {
    // ... DO SOME WORK HERE
  }
}
