SharePoint Survey List - EventReceiver

A survey list behaves differently from other lists. A survey can have many questions spread over several pages, so one response is saved and then updated as the user moves along.

If you need to do calculations once a response is complete, an event receiver is the best option. You must handle both ItemAdded and ItemUpdated.

How to detect a finished response

The Completed field holds 255 while the user is still answering. When the user clicks Finish, it changes to 1. So the receiver should act only when the value equals 1.
