I would reccomend using this method. By creating a custom object for data routines and not plugging it directly into the form's methods you have more flexability. For example, if you windup having to redo the form from scratch, you just drop the data control object you've created on the new form instead of having to cut and past from one form to another. You may also find you'll need to use the same code on another form.

This method really isn't that obscure, your just placing the code in a different object and placing that object on the form. Calling it would require a simple rent.MyDataObject.save()
