5. SharePoint Event Receivers
Event receivers are used for responding to events raised by SharePoint on lists, features, items, or workflows. This chapter provides an overview of what type of event receivers are supported in Visual Studio 2010, how they work, and how to use them.
Introduction to Event Receivers
Events are part of almost every development project you have ever worked on and SharePoint is no different. Because SharePoint is composed of site collections, sites, lists, and items you can imagine that each of these SharePoint objects can raise different types of events. Events provide a powerful way to signal various state changes and are useful if you have to implement business rules tied to SharePoint objects such as lists.
