Find the action trigger at Page_Load

[jerryau]

Hi,

Does anyone know how can I find what was the action trigger (button
pressed) at Page_Load? Because the Page_Load method is called first
everytime anything is posted to the server, I need to know what button
was pressed before performing anything in the Page_Load method. Is it
possible?

Thanks,
Jerry

This will tell you the ID of the control:
string controlId = Page.Request.Form["__EVENTTARGET"];

Though I don't think that is documented behaviour, it's how ASP
manages control events under the hood, so could change in future
versions of ASP.

Jerry,
This question really belongs in the ASP.NET group, since it's about asp.net
page stuff and not really about the C# language specifically.

Thanks, that's exactly what I was looking for

Sorry for posting into the wrong forum, I didn't know there was an
asp.net forum as well .
