Properties beforeproperties itemupdating
I am also running on the track to analyze things good. Here we will discuss Before Properties and After Properties in Event Receiver in Share Point 2013.Are you able to debug your Event Receiver when you modify an item in the list?
Before Properties[internal Name]); string After Value = properties.Note: Allegedly, this does change if the event receiver is synchronous – the before properties are available. Obviously, for Share Point 2007 systems that doesn’t apply – as ‘*ed’ event receivers are always asynchronous.(no updates required since you are changing the value before it gets saved) I would verify that your Event Receiver is attached to the list.Here Randy Williams denoted Before Properties of SPEvent Receiver contains "No Value" for lists. So its good and I got better idea of how before and after events work for both lists and libraries from this post.But i didn't stop my analyze on this, i continue with few more posts, then i identified following post Post 2 : Note : This is untested one, check at your end once before implementing in production.
Before properties are used to get previous values in the event receiver events in Share Point 2013.
