Multiple Child Forms w/multiple tables

I am working on developing a replacement for an existing application which requires many detailed entries for the selection of a product. For example, the customer selects product A. This product will have multiple options, like number of "A" parts, "B" parts, etc. Then each "A" part can have "1", "2", etc. styles. There will also be additional customizations with price variations.

My objective is to use as few forms for data entry for each product as possible. I thought about using a MDI parent form with multiple children forms.

Is this possible? Are there any other ways to design the interface to make it as user friendly and simple to use as possible?

I would appreciate any suggestions or recommendations.

I wouldn't recommend using child forms for data entry since you can barely control what a user is doing on screen. Using child forms enables user to jump back and forth between the forms and risks making erraneous (if not disastrous) entries.

The safest way for data entry is to use modal forms (child forms can't be modal), enforcing a user to close the form (by either saving/cancelling the entry) before he does anything else. If you have lots of fields to fill, you can use tabcontrols (use SSTab, it's easier for design time).

That's it for now...
