Hi Alejandro,

I'll jump in here cause I have a feeling our resident CodeMine guru Gary is busy <g>.

>I am guessing the main form should be based on frmDataManagerFormCustom<

Yes.

>but what should the second form be based on?<

Use frmDataChildCustom as it inherits everything from its Parent form (data and business rules, etc.). This child will do all you asked about (edit, new, or nav with partent). You could even make it "modal" for the new-edit, and then modeless for the nav features. Its all a matter of choice I would think, and how you want your app to operate.
