Itemupdating event fires twice elisabeth elliot dating

Users can change data like the number of moons or the distance to the earth, but they are not able to change the name of the planet.To prevent users from changing the name of the planet, you can develop a Item Updating event receiver.If the name isn’t changed, the changes are saved to the Share Point list.

And if you have Update() or System Update() call on the document / item, this leads to getting an exception message on screen about “XYZ has already been modified”. When force checkout is enabled on document library, this is how the document editing works : When you checkout a document for editing, a local copy of the document is created that saves all the changes made by the user.

This happens due to race condition between the two threads when updating the document / item. At the time of checking-in the document, this local copy updates the original copy (even if there are no changes), then there is another request that does check-in on the document.

Previously I worked as a Premier Field Engineer for Share Point @ Microsoft Belgium.

For 5 successive years I’ve been rewarded as Share Point Server MVP for my contribution to the Share Point community: I developed the U2U CAML Query Builder and its successor the CAML Designer, which I develop together with Andy Van Steenbergen.

You can also use event receivers to validate the data that the user wants to change.

This walkthrough is based on the first one where I have a custom list with planets of our solar system.

I ran into an issue with an Event Receiver that was deployed to a Document Center Site library.

The requirement is pretty simple, when a document is added to the Documents library or an existing document is updated, create a task for someone to review the document's metadata.

The problem is that the Item Updated event in this custom Event Receiver will fire twice under certain circumstances--such as having require document checkout set on the Documents library.
