Developing a Sharepoint application would have all the fun of a video game, if only you had infinite lives.Dangers lurk hidden out there which, if you run into them, can be a blow to your project and waste a great deal of time.So the double-event firing isn’t a bug, it’s just a result of the automatic check-in that occurs when you first add a document to a document library.Note: when the property editor dialog displays, the user has the option to cancel out of the dialog.You just have to check to see if the vti_sourcecontrolcheckedoutby property on the item was cleared: This code is using the Before Properties and After Properties on the properties parameter to see what the value of the vti_sourcecontrolcheckedoutby property on the item was before the update occurred, and what it will be after the update has completed.The vti_sourcecontrolcheckedoutby property identifies who the item is currently checked-out to.The second time they fire it is in response to the document being checked in.

To understand why this is happening, let’s first look at what happens when the user adds a document to the library when the Require Check Out option is disabled: So the net result of this is that the document is uploaded and the Item Adding and Item Added events have fired, which is pretty much what you would expect.Damon gives just one example of a poisoned dagger in the game of Sharepoint Development: The Item Event Receiver.I’m usually disappointed when writers employ oft-overused metaphors to describe a situation.I should also point out that I know the difference between a metaphor and simile in case that was bothering you from the opening sentence.

I am nothing if not a masterful linguist after a beer or two or more.If the user opts to cancel, then only the Item Adding and Item Added events will have fired and the document will be left in a checked out state.
