Let's say I have a form that has a 'Save' button.

What is the proper or most prefered place to store
the code associated with this action? I have come
up with three possibilities and in the most intuitive,
but perhaps not most optimal order:

1. cmdsave.click() - self contained and easy to find

2. thisform.save() or this.parent.save()- almost as easy
to get to the code, and can be called from the button,
menu or toolbar.

3. object.savemethod() - most obscure and least familiar
to me

Does any of this change if I couple the save button with
add, next, prev into a container?

Your thoughts on this matter will be appreciated.
