2.輸入gvGroupUser_RowCommand后双击 ------注分别为：GV属性ID名称—事件名
3. protected void gvGroupUser_RowCommand(object sender, GridViewCommandEventArgs e) ---使用传递到事件处理方法的GridViewCommandEventArgs对象确定引发事件的按钮的命令名 。GridViewCommandEventArgs e对象，与对象参数

if (e.CommandName == "DelUserInGrp") ------获取命令名称 （CommandName属性。可以让窗体上的多个按钮来处理一个事件，可以标记多个按钮，使代码根据窗体上单击的按钮进行逻辑判断）
