Remarks
If override methods are present for insert, update, or delete, SubmitChanges executes these methods instead of the default LINQ to SQL commands.
SubmitChanges starts a transaction and will roll back if an exception occurs while SubmitChanges is executing. However, this does not roll back the changes in memory or tracked by the DataContext; those changes will need to be rolled back manually. You can start with a new instance of the DataContext if the changes in memory are to be discarded.
