Microsoft SharePoint Foundation provides an extensive set of events that you can integrate into library, list, site, and user operations. There are two types of SharePoint Foundation events:
Events that fire before actions occur and that are handled synchronously, allowing custom validation and data processing before lists are modified.
Events that fire after events occur and that are handled asynchronously.
When site events are activated, they are added as registered events for the specified Web site and associated with list instances of the specified type.
Although this element type is only supported for Web site-scoped Features, they can be associated with a content type that is site collection-scoped.
For more information about the file format for item event handler features, see Event Registrations.
