推荐答案

您将需要使用ScriptManager，UpdatePanel并将下拉列表放在更新面板中.处理为国家/地区下拉列表选择的索引更改，并在其中设置州名称.

两个下拉菜单都应该在同一更新面板中.

您可以在网上找到很多与此相关的文章.

You will need use an ScriptManager, UpdatePanel and put dropdown lists in the update panel. Handle the selected index change for the country dropdown and set the state names in it.

Both the drop downs should be in the same update panel.

You can find a lot of articles related to this on web.
