I thought this would be a lot easier, however I’m unable to find a way to determine in my event handler if it is the FIRST check-in of the file..

You see, I’m breaking role inheritance, and selectively inheriting permissions for files in doc libs, yet I wish to do it only once, during the first check-in of the file.

I’ve tried adding an entry to ‘SPListItem.Properties’ in the ItemAdded event in order to indicate if the file is new, however the moment I do ‘SPListItem.Update()’ it vanishes..

I’ve played with the ItemCheckingIn and ItemCheckedIn events with no success…

My only hope at the moment is adding a SPField to the ContentType to indicate if new file or not, but I really wish to avoid it..

ANY IDEAS????

PLEASE HELP ME!

    So I got a solution for this.
    I’m sorry I can’t post code here, I do not have access to internet on my dev machine.
    It should be good enough for everyone.

    Solution:
    During the CheckingIn event I try to access the file using the SHAREPOINT\system(“SPSecurity.RunWithElevatedPrivileges()”). During the first check-in the file is new and not accessible to other users besides the uploader.

    So if I fail getting the file with SHAREPOINT\system it means its new, and I save its Guid in a dictionary in my EventHandlers class.

    Then in the CheckedIn event I simply check if the dictionary contains the Guid of the current item, if it does – FIRST CHECK-IN, if it does not – NOT FIRST CHECK-IN.

    Of course after I’m finished with the file I remove the entry from the dictionary.

    Hope it helps, if you got any questions you are welcome to ask 🙂
