When I delete add, or update my access database, it does not reflect the changes in the database

I have a problem with my C# application. It is a simple add, edit and delete application but when I do any of them, the开发者_StackOverflow社区 database does not reflect any changes given in any of the above actions. But my DataGridView does.

You have to commit your changes. You can have several changes (updates, inserts), and then commit them in one step.
