推荐答案

您需要为此进行事件冒泡，因为子控件不会自行引发任何事件.我们需要为GridView的RowCommand事件创建一个事件处理程序.在此事件处理程序中，我们首先检查传入的CommandName值以确定引发哪个控件的事件，然后采取适当的自定义操作.本文将提供有关引发rowcommand事件的更多信息

技巧/提示:使用提交"按钮从子DropDownList控件引发GridView RowCommand事件 [ ^ ]

You need to do event bubbling for this as child controls do not raise any events on its own & need to be bubbled to GridView their parent.To accomplish this, we need to create an event handler for the RowCommand event of GridView. In this event handler we first check the incoming CommandName value to determine which control''s event is raised and then take appropriate custom action.This article will give more idea on raising rowcommand event

Trick/Tip: Raise a GridView RowCommand event from a child DropDownList control using a Submit button[^]

1只需触发一个DropDown_SelectedIndexChanged事件
2)获取下拉列表的行数
3)找到必需的标签以进行连续更改
4)根据要求设置标签值.

此 [ ^ ]对下拉列表的自动回传几乎没有帮助.

1)Just fire a DropDown_SelectedIndexChanged event
2)Get a row no of Dropdown
3)Find a Required lable to change in a row
4)Set Lable value as per requirement.
