I'm having a problem with multiple people modifying the same item at the same time. In my event receiver (ItemUpdating) I'm taking some of the data and I write it to a separate sql.
If a saving clonflict occurs the data is written to sql, but only the changes in SharePoint from the first person will be stored.
Is there a hash, tag, metainformation associated with a ticket which I can check if the version in the event receiver is still equal to the one on the server? Before I write data to the external sql I want to make sure there will be not saving clonflict after ItemUpdating is ran.
