We have several ways to modify the data in DataTable. In this application, we will demonstrate how to use different ways to modify data in DataTable and update to the source.

1. We use SqlDataAdapter to fill the DataTables.

2. We set  DataTable Constraints in DataTables.

4. We use DataTable Edits to modify data.

3. We use DataRow.Delete Method and DataRowCollection.Remove Method to delete the rows, and then compare them.

5. We use SqlDataAdapter to update the datasource.
