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.
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.
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
