This event occurs before the data is saved to the Share Point list.
Instead when setting the Update Parameters in the codebehind, the control will update the database with the parameter names entered.
After setting the Details View’s Item Updating method, you will need to modify the SQL Data Source’s Update Command, Update Command Type, and Update Parameters.
