How to see what caused PostBack

[Bisser Milanov]

I have few buttons on a page. In Page_Load I would like to determine which
one caused post back. How to do?

Hi,

You can check the value in the Form __EVENTTARGET field.

I forgot, one more way is to overload the RaisePostBackEvent. the
IPostBackEventHandler got the Control ID.

__EVENTTARGET is always empty and I couldn't find such event as RaisePostBackEvent.

OK right buttons dont use the __Dopostback so the EVENTTARGET field is
empty,

1) If you look at the Form.Keys collection you will found the Button ID
that cause the postback.

2) RaisePostBackEvent is a method that you need to overload it :
override protected void RaisePostBackEvent ( IPostBackEventHandler
sourceControl,
string eventArgument)
{
string s = ((WebControl)sourceControl).ID ;
}
