Answer 1

It doesn't appear that you are retrieving any data from the datagridview at all. You are retrieving all the contents from the StudentDB table in the Access database into DataSet ds. You then call GetChanges() on ds and save it into another DataSet called changes. Since the contents of ds come straight from the Access database there will be no changes to save.
