Updating Only Changed Rows in the GridView Control

Matt Berseth wrote a very interesting article on "Bulk Inserting Data Using the ListView Control". The idea is to give the user an Excel like interface where they can edit the rows with custom data and finally click the update button to persist the data in the database. Matt's solution was great but lacks a very important detail. There was no way to know what rows were changed by the user. Matt took the road to update all the rows whether they were changed or not. In this article we are going to take a look at an alternative method of updating only the changed rows.
