To supplement our current web based manual data collection form, I am generating a process within our website that will allow my client to import their records instead of hand entering each record. I have the core process mostly done. I can access the import file, read the records and save them. But, I need to be able to validate the records. I want to check the business rules for each record without having to save the record (as I will save all of the records at the end if all of the records process without error). How do I trigger the rules without a save? Then, how do I access the errors that are generated. I am using MM .NET Classic Entity objects. My experience is limited having worked mostly maintaining currently existing processes.

Any examples would be greatly appreciated as that is the way that I learn the best.
