推荐答案

您好

我认为您期望的是 http://stackoverflow.com/questions/1536930/get-submit-button- id [ ^ ].

Hi

I think you are expecting this http://stackoverflow.com/questions/1536930/get-submit-button-id[^].

一次检查我的代码

Hi,

check my code once

string g = Page.Request.Params.AllKeys[2].ToString();

在上面的代码中，您将获得控件名称，该控件用于控制引发的回发事件

如果"g" 值为" ASP.NET_SessionId "表示该页面不是回发
否则具有控件名称

最好的

In the above code you''ll get control name which control raised postback event

if "g" value is "ASP.NET_SessionId" means that page is not a postback
otherwise it has control name

All the Best
