I am not sure what method you are using to Add New record. This how it works:

Assumption:
You are using a DataTable and DataAdapter

- When you about the Add a record, the autonumber field will use a negative value (which is not insert into the database yet).
- Once you add new, DB will generate a position number as ID. But it will not get updated on the DataTable unless or until you select the table again.
