Hi,

You can check the value in the Form __EVENTTARGET field.

I forgot, one more way is to overload the RaisePostBackEv ent. the
IPostBackEventH andler got the Control ID.

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) RaisePostBackEv ent is a method that you need to overload it :
override protected void RaisePostBackEv ent ( IPostBackEventH andler
sourceControl,
string eventArgument)
{
string s = ((WebControl)so urceControl).ID ;
}

Hi friends, This is my question.... From the Page Load event (or Page Init event), I would need to find which event had occurred that caused a PostBack, for example was it a event fired from the datagrid that caused a postback, or was it from a linkbutton, or was it from any other control on the page that have PostBack capabilities ? I am pretty sure this information is captured somewhere before the event is sent to its appropiate...

I have a DataGrid with a templated column that displays ImageButtons. I need to know if one of these buttons caused the postback or just another button on the form. If one of these buttons caused the postback than I don't want to do a DataBind otherwise I do. I know __EVENTTARGET doesn't return this information. Is there anything else that does? Thanks, Joe

How do I get the name or identify the control that caused the page postback. I need the information during page init. Reason why, because I need to tell usercontrol_1 that usercontrol_2 button was clicked and therefore need usercontrol_2 public properties to be passed to usercontrol_1 public properties in the case of the event. thanks

How can I tell which control caused a postback? I have several controls that cause a postback, and I want to take different actions depending on which was activated.

If I can tell what caused the postback, then I can at least take action accordingly. Or should I be...
