Try adopting the existing examples out there to my code with no luck. What's the absolute minimum needed to get a calendar to show? Is there an example out there that creates a schedule, day or monthview with a single calendar, no activities needed in code behind? Have spent 2 weeks trying to get something anything to show on the calendar.
Never mind, found an example here:

Wish it was specified the minimum items needed to generate a calendar view. Seems that nothing renders without a calendar owner and a calendar group.l
I'm sorry about the difficulty you've been having. There is a help topic that discusses the minimum requirements here. Calendar groups are not required unless you want to display multiple calendars but you should set the CurrentUserId of the DataManager.
