You can use dynamicBackColor the way Ko said, based on a special field on your cursor. Just make all your validation code change that field to indicate if the row is valid or not. If you want to do this field by field, you can add many "valid fields" or just a single string field with a character flag for each "real field".

Hope this helps.
