If you like to have arabian or jalalian date time, you have to write a simple converter and then apply it to the fields where a date is shown. I've attached a simple example to demonstrate this approach. You might also like to set globaly the CurrentUICulture in App.xaml.cs for the rest of the Application.
your sample code work only for change language and region, but datetime values are not in jalalian or arabian datetime yet.
could you give me a sample that convert Gregorian datetime to jalalian or arabian datetime ?
Thanks a lot for your good support.

Currently the RadDateTimePicker control doesn't support Persian and Hijra calendar and that's why the RadGanttView doesn't support them either. There is a feature request logged into our PITS here. You can track it and vote for it there.
