       System.Globalization.GregorianCalendar
        System.Globalization.DateTimeFormatInfo info = culture.DateTimeFormat;
        info.AbbreviatedDayNames = new string[] { "ی", "د", "س", "چ", "پ", "ج", "ش" };
        info.DayNames = new string[] { "یکشنبه", "دوشنبه", "ﺳﻪشنبه", "چهارشنبه", "پنجشنبه", "جمعه", "شنبه" };
        info.AbbreviatedMonthNames = new string[] { "فروردین", "اردیبهشت", "خرداد", "تیر", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };

        info.PMDesignator = "ب.ظ";
        info.ShortDatePattern = "yyyy/MM/dd";
        info.FirstDayOfWeek = DayOfWeek.Saturday;

        System.Globalization.PersianCalendar cal = new System.Globalization.PersianCalendar();

        typeof(System.Globalization.DateTimeFormatInfo).GetField(
            "calendar", System.Reflection.BindingFlags.Public |
            System.Reflection.BindingFlags.Instance |
            System.Reflection.BindingFlags.NonPublic).SetValue(info, cal);

        object obj = typeof(System.Globalization.DateTimeFormatInfo).GetField(
            "m_cultureTableRecord", System.Reflection.BindingFlags.Public |
            System.Reflection.BindingFlags.Instance |
            System.Reflection.BindingFlags.NonPublic).GetValue(info);

        obj.GetType().GetMethod("UseCurrentCalendar",
           System.Reflection.BindingFlags.NonPublic |
           System.Reflection.BindingFlags.Instance).Invoke(obj,
           new object[] { cal.GetType().GetProperty("ID",
   System.Reflection.BindingFlags.Instance |
   System.Reflection.BindingFlags.NonPublic).GetValue(cal, null) });

        typeof(System.Globalization.CultureInfo).GetField("calendar",
            System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance |
            System.Reflection.BindingFlags.NonPublic).SetValue(culture, cal);

        System.Threading.Thread.CurrentThread.CurrentCulture = culture;

        RadDatePicker1.Culture = culture;
        RadDatePicker1.SelectedDate = DateTime.Now.Date;
        TimeSpan ts = new TimeSpan(3, 30, 00);
        RadDatePicker1.Calendar.FastNavigationSettings.CancelButtonCaption = "انصراف";
            RadDatePicker1.Calendar.FastNavigationSettings.OkButtonCaption = "تایید";
            RadDatePicker1.Calendar.FastNavigationSettings.TodayButtonCaption = "امروز";

Hello Hesam,

I'm not sure that I understand you completely. At this point RadCalendar doesn't support cultures that use calendars other than Gregorian. Unfortunately there is no workaround for this limitation.

Please excuse us for the inconvenience.
