I have a user control which is basically like the maintenance tool strip.  It has save, new, delete, edit, and undo buttons which function on a business object and linked to controls on the form.  I have some business rules setup which prevent duplicate names from being entered into the database.  This works perfectly when doing a New operation and saving.  However, if I edit a record and then try to save it will give me a broken rule for things that haven't changed.  For example, I have a FirstName and a LastName field.  I want to only edit the FirstName, but leave the LastName alone.  If I do this, and then save it will give me a broken rule on LastName if I'm not allowing duplicates.  Is there some way around this?  Maybe a setting that tells the BO not to check rules on fields that haven't changed from their original state?

Good.  Glad to help
