I have made a Relation in my 2 Tables but when I wanna fill the DataSet by DataAdapter It Gives me following error:
An unhandled exception of type 'System.Data.ConstraintException' occurred in system.data.dll
Additional information: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.
PLEASE HELP ME, I become stuck in this simple problem!!!
