For example: We need to use DateTimePicker for FarsiCalendar. But we only can use FarsiCalendar sub class to convert Dates and Our DateTimePicker can not show JALALI calendar as HIJRI or Gerigurian calendars!
We also installed LIP for Farsi(Persian) language on Our Windows 7 (64bit) but in windows 7 calendar we must use other kind of calendars!
How we can use a Microsoft standard DateTimePicker for Farsi(Persian) language in C# and etc.?
