I was thinking of the best generic way to make some fields in a table required. I'd like to check for the values in objects before the actual save takes place. What I thought I would try is to create a new logical property called "required" on all appropriate data objects (textboxes, editboxes, drop-downs, etc.). Then, in my pre-save hook I could just go through the container and make sure all objects with required=.T. are not empty.

Anyone have any ideas/comments about this approach?
