Sharepoint-Property to identify the source of the document/item in ItemAdded Event

Question

I want to increment the metadata whenever the copy operation is trigerred.

       public override void ItemAdded(SPItemEventProperties properties)
        {           
            try
            {   
                this.DisableEventFiring();
                SPSecurity.RunWithElevatedPrivileges(delegate()
                {
                string oid = string.Empty;                        
                using (SPWeb web = properties.OpenWeb())
                {
                     SPList list = web.Lists[properties.ListId];
                     SPListItem item = list.Items[properties.ListItem.UniqueId];      
                     String Source=item.CopySource.toString();
                 }
              });
          }
Catch()

Here Item>copysource returns empty string So it's difficult for me to check wheter the event has fired due to copy operation

Answer 1

You don't need the RunWithElevatedPrivileges, because ItemAdded event already runs with as privileged user.
