推荐答案

好吧，我有这个问题就解决了​​。
为了处理的SelectedIndexChanged 的嵌套GridView控件DropDownList的，你必须只设置自动回属性真实和点SelectedIndexChange事件的一些过程。

ok, the issue I've had is solved. To handle SelectedIndexChanged for DropDownList nested inside GridView you have to just set AutoPostback property to true and point SelectedIndexChange event to some procedure.

问题我的原因是，我没有在Page_Load中功能检查（数据绑定到GridView的期间）以下规则：如果没有Page.IsPostBack然后。就这样。所以，不要忘记这样做，请！ ：）

The cause of issue I had was that I didn't check in Page_Load function (during binding data to GridView) following rule: If Not Page.IsPostBack Then. And that's all. So don't forget to do it please! :)
