I have a code that changes the username in various SharePoint lists, mostly by the "Author" column. It all works fine on normal lists, but it doesn t seem to work on the "Shared Documents" list which is a document library.
Whether I change the username in "Created By" or "Document Created By", the change doesn t seem to take effect. The item.Update command doesn t throw any exception, but it clearly doesn t update the field(s).
What can I do if I want to change this field through code?
Thanks
I found a workaround for my problem.
Only the last field I m trying to update is being "overwritten".
So, while the following code won t work:
item["Author"] = 22;
item.SystemUpdate();
This one will do:
item["Author"] = 22;
item["Modified By"] = item["Modified By"]; //Or any other field
item.SystemUpdate();
Maybe this could help How to change the value of "Created By"...
Pay attention on AllowUnsafeUpdates property.
