Is there anyway to find out which control fired the postback in server-side
code?
Like in windows programming "Form.ActiveControl" ?

You can peak under the covers and take a look at
Request.Form["__EVENTTARGET"]
which will give you the UniqueId of the control which cause the event to
fire. If the contro was a WebControls.Button then __EVENTTARGET will
unfortunetly be blank, but the button's unique ID will be in the
Request.Form collection...

Thanks, and I figured something like that but I wanted a standard .NET way to
do it.

If postback happen, it will fire corresponding post back event in the server
side. That post event will have sender as one of its parameter, with which
you can identify which control caused the postback.
But if you want it to find it in Page_Load, only option is
Request.Form["__EVENTTARGET"]. This method will only work if your control
has autopostback property set to true

I understand all that but wouldnt it be nice to just have a property of the
page called Postback control that would be the control that caused the
postback. It's in the __EventTarget form element anyway.

It would be, but it's possible the control doesn't exist yet. You get into
complexe page event issues...but yet, it really really would be nice..
