The dates displayed in different views come from two different sources, therefore when one of the sources changes, you have to manually update the other source. More specifically, the dates displayed in the Timetable view are obtained from the Calendar.TimetableSettings.Dates collection, while the month in the SingleMonth view is specified by Calendar.Date. Therefore, when switching from Timetable to SingleMonth, you can inspect the first DateTime in Calendar.TimetableSettings.Dates and assign it to Calendar.Date.

As for the WeekRange view, it cannot display navigation buttons, but there is a sample, which illustrates how you can implement unlimited scrolling in this view. The sample is called UnlimitedScrolling.
