By default RadCalendarView uses the current device's locale to initialize the values that are displayed along with some other calendar specifics like which is the first day of the week. Here's an example with of the calendar run on a device where the language is set to English (United States):
If you want to provide a static locale which disregards the user's preferences, you can use the calendar's setLocale(Locale) method and set the locale of your preference. Here's an example with the local
calendarView.Locale = Java.Util.Locale.France;
The result will be that the calendar will display the names of the days and the month in French and the first day of the week will not be
Sunday as with the previous example but
RadCalendarView displays the dates in accordance with the
java.util.GregorianCalendar. If you would like to use another
Calendar implementation you can apply it with calendar's setCalendar(Calendar) method.
