Hi All.
My WPF UI form binding to EF business layer. And I would like to validate duplication by match some values. For instance, if user try to create new record by entered data to fields EmpNo, FirstName, LastName, EmailAddress, Department and then click save button. The save event is matching data for fields EmpNo, FirstName, LastName and EmailAddress. If will found record where all 4 fields are matched in that case duplication message should be popup. How to do that?
Thanks.
