Kevin,

Yes, you're on the right track, although we use the paradigm that if a zero key is passed then it's a new entry, otherwise the key is used to get the data.

Also, I wouldn't have the Form itself do any of that. It simply tells the Biz class (or a Web Service) to get a DataSet based on the key. The Form itself doesn't need to know if you're adding new data or updating existing data.
