I Used this Class to Localize RadScheduler to Persian Calendar:
using System.Globalization;
using System.Collections.Generic;
using System;
using System.Reflection;
public class PersianCulture : CultureInfo
{
    private readonly Calendar cal;
    private readonly Calendar[] optionals;

    public PersianCulture()
        : this("fa-IR", true)
    {
    }

    public PersianCulture(string cultureName, bool useUserOverride)
        : base(cultureName, useUserOverride)
    {
        //Temporary Value for cal.
        cal = base.OptionalCalendars[0];

        //populating new list of optional calendars.
        var optionalCalendars = new List<Calendar>();
        optionalCalendars.AddRange(base.OptionalCalendars);
        optionalCalendars.Insert(0, new PersianCalendar());

        Type formatType = typeof(DateTimeFormatInfo);
        Type calendarType = typeof(Calendar);

        PropertyInfo idProperty = calendarType.GetProperty("ID", BindingFlags.Instance | BindingFlags.NonPublic);
        FieldInfo optionalCalendarfield = formatType.GetField("optionalCalendars",
                                                              BindingFlags.Instance | BindingFlags.NonPublic);

        //populating new list of optional calendar ids
        var newOptionalCalendarIDs = new Int32[optionalCalendars.Count];
        for (int i = 0; i < newOptionalCalendarIDs.Length; i++)
            newOptionalCalendarIDs[i] = (Int32)idProperty.GetValue(optionalCalendars[i], null);

        optionalCalendarfield.SetValue(DateTimeFormat, newOptionalCalendarIDs);

        optionals = optionalCalendars.ToArray();
        cal = optionals[0];
        DateTimeFormat.Calendar = optionals[0];

        DateTimeFormat.MonthNames = new[] { "فروردین", "اردیبهشت", "خرداد", "تیر", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };
        DateTimeFormat.MonthGenitiveNames = new[] { "فروردین", "اردیبهشت", "خرداد", "تیر", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };
        DateTimeFormat.AbbreviatedMonthNames = new[] { "فروردین", "اردیبهشت", "خرداد", "تیر", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };
        DateTimeFormat.AbbreviatedMonthGenitiveNames = new[] { "فروردین", "اردیبهشت", "خرداد", "تیر", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };

        DateTimeFormat.AbbreviatedDayNames = new string[] { "یکشنبه", "دوشنبه", "ﺳﻪشنبه", "چهارشنبه", "پنجشنبه", "جمعه", "شنبه" };//{ "ی", "د", "س", "چ", "پ", "ج", "ش" };
        DateTimeFormat.ShortestDayNames = new string[] { "یکشنبه", "دوشنبه", "ﺳﻪشنبه", "چهارشنبه", "پنجشنبه", "جمعه", "شنبه" };//{ "ی", "د", "س", "چ", "پ", "ج", "ش" };
        DateTimeFormat.DayNames = new string[] { "یکشنبه", "دوشنبه", "ﺳﻪشنبه", "چهارشنبه", "پنجشنبه", "جمعه", "شنبه" };

        DateTimeFormat.AMDesignator = "ق.ظ";
        DateTimeFormat.PMDesignator = "ب.ظ";

        /*
        DateTimeFormat.ShortDatePattern = "yyyy/MM/dd";
        DateTimeFormat.LongDatePattern = "yyyy/MM/dd";

        DateTimeFormat.SetAllDateTimePatterns(new[] {"yyyy/MM/dd"}, 'd');
        DateTimeFormat.SetAllDateTimePatterns(new[] {"dddd, dd MMMM yyyy"}, 'D');
        DateTimeFormat.SetAllDateTimePatterns(new[] {"yyyy MMMM"}, 'y');
        DateTimeFormat.SetAllDateTimePatterns(new[] {"yyyy MMMM"}, 'Y');
         */

    }

    public override Calendar Calendar
    {
        get { return cal; }
    }

    public override Calendar[] OptionalCalendars
    {
        get { return optionals; }
    }
}

And in Global.asax:
protected void Application_BeginRequest(object sender, EventArgs e)
    {
        var persianCulture = new PersianCulture();
        System.Threading.Thread.CurrentThread.CurrentCulture = persianCulture;
        System.Threading.Thread.CurrentThread.CurrentUICulture = persianCulture;
    }
everything is ok just in select start and end date.

I found mentioned class to conver georgian Calendar to Persian Calendar. Everything in ok but when user change time in RadDatePicker popup Caledar (1391/12/08) is in persian but in DateInput is in georgian format(2013/03/05). I mean DateInput should be 1391/12/08 when I select year 1391, day 08 and month 12 in calendar.

2.Picture moffiederror.png:
I have this problem in updating appointment with mouse click in main page. when I press mouse down and change start time of appointment I got an error because start Time is changed therefore is in georgian format but endtime is not changed therefore is in Persian Format. Persian year is less than georgian. I've got error: StartTIme should be less than endTime.
I solved problem in this type. I changed Starttime to Georgian in PatientScheduler_AppointmentUpdate with a trick(endtime and startTime variables are used to store modified time of Day):
protected void PatientScheduler_AppointmentUpdate(object sender, AppointmentUpdateEventArgs e)
    {
        TimeSpan endTime = e.ModifiedAppointment.End.TimeOfDay;
        e.ModifiedAppointment.End = e.Appointment.End;
        e.ModifiedAppointment.End = e.ModifiedAppointment.End.Add(endTime - e.ModifiedAppointment.End.TimeOfDay);

        TimeSpan startTime = e.ModifiedAppointment.Start.TimeOfDay;
        e.ModifiedAppointment.Start = e.Appointment.Start;
        e.ModifiedAppointment.Start = e.ModifiedAppointment.Start.Add(startTime - e.ModifiedAppointment.Start.TimeOfDay);

        if (e.ModifiedAppointment.Start > e.ModifiedAppointment.End)
        {
            e.Cancel = true;
            //TODO: Exceptio Handeling
            throw new Exception("start time must be before end time");
        }
}

The main problem is why date-time change to Georgian format with this class? Is there any solution to convert it to Persian Format in clientside?

Hi shahab,

Unfortunately RadScheduler does not support PersianCalendar so far and that is why it is expected that there are some errors in its functionality when trying to add it. I have isolated the scenario in a sample web page would you please review it and let me know what else should be added so it works the same way as at your side.

This way we will be able to inspect the issues faced and be more helpful.

Dear Plamen,
I don't what's happen when start in advancedForm but it work with this solution:

<telerik:RadScheduler runat="server" ID="RadScheduler1"

EditFormDateFormat="yyyy/MM/dd"

OnAppointmentUpdate="RadScheduler1_AppointmentUpdate" OnAppointmentInsert="RadScheduler1_AppointmentInsert" SelectedView="MonthView"

HoursPanelTimeFormat="HH:mm"

StartInsertingInAdvancedForm="True"

StartEditingInAdvancedForm="True">

<MonthView HeaderDateFormat="MMM dd" DayHeaderDateFormat="MMM dd"/>

</telerik:RadScheduler>

As highlighted in picture I Select start time in Insert mode therefore DateInput change to Georgian but I do not change endtime therefore it is in Persian. I can not attach project. I just Change .aspx form.
I can Add this to .xml:

<Appointment>

<ID>56</ID>

<Subject>ghhgjghj</Subject>

<Start>2013-04-04T15:00Z</Start>

<End>2013-04-09T16:00Z</End>

<Resources>

<Room Key="1" />

<User Key="1" />

</Resources>

</Appointment>

Hello shahab,

Thank you for providing more information about the issue. You will have to change the dates in the date pickers from the server. Here is the code that will let you achieve it:

protected void RadScheduler1_FormCreated(object sender, SchedulerFormCreatedEventArgs e)

{

RadDatePicker startDate = e.Container.FindControl("StartDate") as RadDatePicker;

startDate.AutoPostBack = true;

RadDatePicker endDate = e.Container.FindControl("EndDate") as RadDatePicker;

endDate.AutoPostBack = true;

}

Hope this will be helpful.

Kind regards,

It is not ok yet!
e.ModifiedAppointment.Start is in GeorgianFormat and e.ModifiedAppointment.End is In Persian Format. Because I Change EndTime.

WHen I Set

<telerik:RadDatePicker runat="server" ID="StartDate" CssClass="rsAdvDatePicker" Width="150px" SharedCalendarID="SharedCalendar" Skin='<%# Owner.Skin %>' Culture='<%# Owner.Culture %>' MinDate="1900-01-01" AutoPostBack="True">

It id ok just first time. After change selection Persian Calendar change to Georgian

Hi shahab,

After making both DatePickers AutoPostBack true they updated their time to Persian time accordingly without any code in the AppointmentUpdateEvent. I am attaching an updated sample web page again. Here is a video of my test. Please review it and let us know if you have further questions.

Dear Plamen
Change starttime/endtime more than once. At first every thing is ok (2.png). DateInput and PopupCalendar are in Persian Format but after two or more times it is in Georgian format(1.png)
