Then, for each activity that affects the entire workflow, bind that activity’s correlation token to the correlation token of the On Workflow Activated activity.Before Properties and After Properties are available for the different event receiver classes. With the exception of feature events, here is a full list of available Share Point events, event receivers, and event hosts for quick reference.However, this post only focuses on the Before Properties and After Properties of the list item event receiver (SPItem Event Receiver). There is a difference between the behaviour of Before and After properties when dealing with document libraries versus when dealing with lists.Share Point has a built-in infrastructure that allows certain SP objects to raise events that can be handled by custom code.These events could be web events (Web Adding, Web Provisioned, Web Deleting etc), feature events (Feature Activated, Feature Deactivated etc) or most popularly, list item events (Item Updated, Item Updating, Item Added etc).
