• 3、DataList 按钮添加自定义事件
• 在控件模板中添加 Button、LinkButton 或 ImageButton 控件。
  将按钮的 CommandName 属性设置为标识其功能的字符串，如 “SET” 或 “Copy” 。
  使用 CommandArgument 属性将行的索引或者其他参数传给事件处理方法。
  创建用于容器控件的 ItemCommand 事件的方法。在该方法中，执行下列操作：
• 检查事件参数对象的 CommandName 属性来查看传入什么字符串。
• 读取 CommandArgument 传递过来的参数
• 为用户单击的按钮执行相应的逻辑。

protected void DataList1_ItemCommand(object source,
DataListCommandEventArgs e)
{
       if (e.CommandName == ""SET)
      {
          //TODO
      }
}
