Add & Update are working perfectly, but delete doesn't update in the db. While application is running it shows that data is deleted, but when I run again, I see the same data, so its not physically deleting from the db. Add & Update both are working perfectly even after re-running.Can anyone tell me where am I going wrong in delete part. The row is also proeprly selected. No exceptions, yet why not deleting physically.
