You don't have to give up the ControlSource property. Binding to properties in the case of a form and to the cursor in the case of a grid sounds over-complicated to me. KISS. :) Just bind to the cursor all the time and have the form signal the business objects. Having the answer "it depends" for everything guarantees complexity. How do you plug in a toaster? It doesn't depend - that decision has been engineered out of the discussion. If you want to go solar or wind generated, you still feed the electricity into the house so you don't have to re-do all the wiring. :) _______________________________________________ Post Messages to: ProFox@leafe.com Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/[EMAIL PROTECTED] ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
