Event Reciever firing twice sharepoint 2010

Question

Hi I have a event receiver(item adding,item editing,item added), it was working fine before ...now it has started to fire twice...any suggestions?

Answer 1

In my case it was accidentally doubled registration of event reciever. Check it with SharePoint Manager 2010 for example.

Answer 2

Before you call update on the item in your receiver, are you calling this.DisableEventFiring() and then this.EnableEventFiring() straight after?

Answer 3

Here's an article on the subject from Simple-Talk - Managing ItemUpdating and ItemUpdated Events Firing Twice in a SharePoint Item Event Receiver. Well worth reading.

Answer 4

I had the same problem this week when I wanted to publish a page directly from the "Publish" ribbon button.

My event receiver fired three times in a row. The first time for the check in, The second time for the publication, and the last time to approve it.

What I dit was checking the afterproperties, to see if I will get the correct values. I did not find another solution.

If you are updating your item in the event receiver, than you could try James Love his solution.
