How to add identity column to datatable using c#

Question

How to add identity column to datatable using c#. Im using Sql compact server.

Answer 1

You don't do autoincrement on DataTable (or front-end for that matter), unless you want to make your application a single user application only.

If you need the autoincrement, just do it in database, then retrieve the autoincremented id produced from database to your front-end.

See my answer here, just change the SqliteDataAdapter to SqlDataAdapter, SqliteConnection to SqlConnection, etc : anyway see why I get this "Concurrency Violation" in these few lines of code??? Concurrency violation: the UpdateCommand affected 0 of the expected 1 records
