SPItemEventProperties class
Contains information about list item events.
Namespace: Microsoft.SharePoint
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
The SPItemEventProperties class holds information about an item event, including fixed properties of the event such as event type, user name, and URL; it also includes Before and After properties of the list item for which the event is triggered when properties are available. For After events, the definitions of Before and After properties are straightforward: Before properties refer to settings that existed before the event occurred, and After properties refer to the settings that exist after the event has occurred. For Before events, however, Before properties refer to current item settings before the event occurs, while After properties refer to settings the item will have after the event occurs.
The following code example uses the SPItemEventProperties class to limit the number of items that can be added to a list.
