try this:

Try
' your code goes here
Catch ex As ConstraintException 'the exception type that you want to catch
Throw New Exception("Test", ex)
Catch all_ex As Exception 'catch all unhandled exceptions
' do something here
End Try

try this: set the EnforceConstraints of your dataset to false

this.myDataSet.EnforceConstraints = false;

this will stop the messages. But you will have to find a way to create your messages. on RowChanging or CurrentCellChanged events
