You will need UpdatePanel form ASP.NET AJAX Extensions to make it work.
Basic requirements:
Both Calendar and DayPilotCalendar in the same UpdatePanel (you can use triggers later, but start with this configuration)
Handle SelectedDayChanged of the standard Calendar control (I'm writing from memory, it's not the correct name but you wil find it). In the event handler, change StartDate property of DayPilotCalendar and call DayPilotCalendar.DataBind().
