Right now I have a SPItemEventReceiver that overrides ItemCheckedIn. It checks out the file, creates/marks a hidden field, and checks it back in. The reason for setting a property on the file is to prevent the process from changing the item again; it modifies permissions of the item.

This works, but has some side-effects. The alerts don't work properly due to the Alert system detecting System modifications and the item/file's "Modified By" field gets set to System Account.

Some options include,

  1. Fix/work-around the side effects
  2. Put the data somewhere else
    • put the data in web.Properties
    • create a list in which to put the data
  3. Find a way to tweak the Item properties before the initial check-in
  4. Find a way to detect the a file is new right after it is checked in.

I know how to do 2 and might accomplish 1, but I've struggled finding a way to do 3 or 4.

Update: Versioning is not on, but Checkout is required.

Do you have versioning turned on? –  Rob D'Oria Aug 23 '11 at 15:31

I would try using SPListList.SystemUpdate() in the event handler. I suspect that you're using SPListItem.Update() at the moment. SystemUpdate() won't change the modified date or user.

I did not realize that was a side-effect of using SystemUpdate. Thanks. –  oglester Aug 23 '11 at 19:54
    
No problem, I come across that one in nearly every project... –  Andy Burns Aug 24 '11 at 8:15

I found a solution that merge 3 & 4.

  1. In ItemCheckingIn, add a property to the changed properties list. properties.AfterProperties.ChangedProperties.Add(FieldName, value)
  2. In ItemCheckedIn, you can check the property of the item, which will get the value set in ChangedProperties. var s = Convert.ToString(properties.ListItem[FieldName]);

So, to that takes care of setting a value without checking-out/in. the value in this case is a timestamp, which I can detect if it is old or not. If the current time is within a few seconds of the timestamp, then I know the file is new.
