ItemUpdating called twice after ItemAdded in event receiver

Question

I've created an event receiver to handle the ItemAdded and ItemUpdating events on a document library in SharePoint 2010. I've encountered a problem where when I add a document to the library (e.g. by saving it back from Word) the ItemAdded method is correctly called however this is then followed by two calls to ItemUpdating. I have removed all code from my handlers to ensure that it's not something I'm doing inside that is causing the problem. They literally look like: ``` public override void ItemUpdating(SPItemEventProperties properties) { } public override void ItemAdded(SPItemEventProperties properties) { } ``` Does anyone have a solution to this issue? Here is my elements.xml file for the event receiver: ``` DocumentsEventReceiverItemUpdating ItemUpdating $SharePoint.Project.AssemblyFullName$ My.Namespace.DocumentsEventRecei…

Accepted Answer

Problem is that In `Document library` event handlers during `Item Updating` also checking that `Document` is it in Check In mode or Check Out. That's why it is called twice.

You should put your code in

```
 public override void ItemUpdating(SPItemEventProperties properties)
  {  
    base.ItemUpdating(properties);
    if (properties.AfterProperties["vti_sourcecontrolcheckedoutby"] == null && properties.BeforeProperties["vti_sourcecontrolcheckedoutby"] != null)
     {
       //do stuff
     }
  }
```
