This event can be used in response, for example, to a form edit, a datasheet post, an object model call, or a Web service call.
When you add a new item, only the ItemAdded event is raised. However, in cases where Explorer View is used, both the ItemAdded and this event are raised. In such cases, this event always occurs after the ItemAdded event occurs.
Before and After properties are guaranteed for postback events on documents, but Before properties are not available for postback events on list items.
