Event itemupdating which
In Share Point you can add event handlers to the different lists, document libraries and content types within a Share Point site. Event handlers defined for these events are executed before the operation is executed on the content database. You can define event handlers for the different operations on list items, like adding a list item, updating a list item or deleting a list item. Events ending by –ing are synchronous events: Item Adding, Item Updating, Item Deleting.Event hosts are common Share Point objects that expect to receive events—in other words, objects whose event receivers "listen" for Share Point events.These Share Point event host object types include instances of common objects such as Share Point site collections, sites, and lists.If you don’t find the answers to your questions on this blog, you can always post your questions to the Share Point 2010 forum or the Share Point 2013 forum. Now go to the event receiver file and you'll get a bunch of methods base on your selection during event receiver creation. Note that the Item Added method is used instead of the Item Adding method.
This even happened when I copied and pasted the script from one game to another, and it still refused to fire the event.
There is an excellent and very detailed post about this property.
You will find a lot of code snippets wrapped in a Run With Elevated Permissions construct.
An event receiver is a piece of managed code that responds to Share Point events when specific triggering actions occur on a Share Point object.
Triggering actions include activities such as adding, updating, deleting, moving, checking in, and checking out.
