Hi Ed,
Thank you for the update.
Query 1: CalendarBehavior object is not aware of Navigation or any other objects available from the parent page.
Since, provided information is not sufficient to analyze your requirement. Can you share the more details about your requirement? Which helps us to analyze and resolve your requirement.
Query 2:
Based on provided information we have analyzed your requirement "Set the inline item for the cells which doesn't contains appointment" as per calendar implementation the inline item template only applicable for the inline view which contains events and the template doesn't work for the inline view which doesn't contains event.
But you can achieve your requirement using OnInlineLoadedEvent, in this event you can set the custom view to inline view based on the appointment details, we have prepared simple sample for the same.
