In VB:

If Not Request.Params("ButtonA") is Nothing Then
'Do stuff if button A was pressed
Else
'Do stuff if button A wasn't pressed
End If

However, I wouldn't recommend it. You've now, potentially, got two
places where code reacts to button presses - in the Page Load event and
in the button Click event. A future maintainer (or a future you) may be

if they don't spot the code in Page Load, and spend valuable
time trying to diagnose why the page acts differently when the button
is pressed.

Perhaps if you could elaborate on what behaviour you're altering, we
could suggest some viable alternatives?

In the Form Load event handler, can't you interrogate the sender object
to determine whether or not button A was pressed?
