基本上，一旦从DropDownList中选择了一个项目，就会发生回发，并在GridView中填充包含该特定项目的字段.

Hi, I want to populate a GridView in a web application with a field selected from a DropDownList.
Basically, once you select an item is selected from a DropDownList, a postback happens and a GridView is populated with the field that contains that particular item.

推荐答案

在SelectedIndexChanged中下拉事件，您可以在网格上调用DataBind，这将导致它进行数据绑定.设置网格，以使参数之一是控制参数，并将其指向您的下拉菜单.

In the SelectedIndexChanged event for your drop down you can call DataBind on your grid which will cause it to databind. Setup your grid so that one of the parameters is a control parameter and point it to your dropdown.
