Try [DisplayFormat(ConvertEmptyStringToNull = false)] This post isn't exactly your scenario but it could be related to the strings you have (nvarchar) and they might be defaulting to null? http://stackoverflow.com/questions/3129080/server-side-validation-of-a-required-string-property-in-mvc2-entity-framework-4
worth a try anyway :) the other way is to just set it on the client and then ignore what the client provides.

If I create a new Product class, display it in a Dataform to allow the user to edit price, etc. I can't submit product to the domain service because validation fails "CreatedById can not be null". It makes no sense to set those values on the client side as they could spoof those files. I have logic on the domain service side that looks at the current authenticated user and automatically sets those fields. > > But I can't submit them because validation keeps failing on those 2 fields. > Is there a [NotRequired] property I could put on the domain service metadata file? > -David Burela > > _______________________________________________ > ozsilverlight mailing list > ozsilverlight@ozsilverlight.com > http://prdlxvm0001.codify.net/mailman/listinfo/ozsilverlight >
