Right now I have 14 maintenance forms. All of these forms have the exact functionality, they just display and deal with different tables of data. They are currently in separate forms and inherit visual style from a parent form. The client has asked, for a second time now, to have changes made to the way all of the forms behave. (This app is not live yet, so more changes may be coming.)

Should I recreate all of these forms and make them into one form with an enum parameter in the constructor to tell which table I am maintaining or just leave them separate and deal with making changes in multiple places and having to test them in multiple places? I am using 2005, so I was thinking about using Partial Classes to hold the event handlers for the various controls based upon the table being maintained.

I guess I could have a Maintenance class that does the processing that is similiar on all of the forms...

Thoughts or recommendations?

PS - There is probably room to squeak this out in the budget.

Thanks in advance.
