So add this code to your Save button: Data Row row = ds. That's enough to update the underlying database with your new record.

The Data Adapter is linked to the database itself, and can issue Update, Insert and Delete commands.Of course, we have yet to call our new method into action. Add a try catch statement: try catch (Exception err) For the try part, add the following: try As the first line of the try part, we have this: obj Connect.
