I've created a library in SP2010 where the primary content type is a Document Set. I would like to display the document sets in a calendar view, but when I go to do so nothing shows up. These document sets are not the built-in Sharepoint Event content types, but they do have start and end date columns, so I would think they could be displayed as a calendar. Any ideas?
Do you mean you create custom document set content type? What is the parent content type for the document set content type?
