:o)
That is why Events must call methods.
Move all code from Click() to some custom event.
Than its easy:
Add parameter to this methiod that will show you from where it is called.
I.e. from Button.Click call this method that way:

thisForm.MyButtonClickHandler(.t.)

* and from everywhere else:

thisForm.MyButtonClickHandler(.f.) && or thisForm.MyButtonClickHandler()
