Saving from a DataGrid on a DataTable.RowChanged Event

In Framework version 1.0, which my client is constrained for budgetary
reasons to use, is it possible to save to an Access database a row in a
DataGrid when the user navigates to the next row--as Access itself behaves?
Or is it necessary to use a "Save" button? I've observed that the HasChanges
property of the underlying DataSet is False in the DataTable.RowChanged event
but True in a btnSave_Click event. Apparently--please correct me if I have
the wrong impression--.Net does some additional work on the DataSet after the
RowChanged event before the next user action. I don't know of any other
events that might be fired by navigating to the next row.

Thank you for any insights on this.
