Handling event when approving a document.

In SharePoint,

using an event receiver, how do we find out when a user has approved a document in a document library?

I would think it should be captured in ItemAdded or ItemAdding event.

Any ideas?

Thanks.

From stackoverflow

• ItemUpdated is the event receiver to use, unless you want to "override" the approval (and maybe keep the item unapproved) - in this case you should use the ItemUpdating.

  To check if the item is approved you could try this code:

  public override void ItemUpdated(SPItemEventProperties properties)
  {
     if (properties.ListItem["Approval Status"] == "Approved")
     //Do Something
  }
  

  Hope it helps
