  Hi
  i've tested out your scheduler control whether does it support persian culture or not.
  i found this link which help me very much!
  almost everyThing is ok except month view. in month view the calendar does not works correctly and also gregorian month name display in the first of the week day that i don't see it.
  in attention to that post which this schedule control does not support persian calendar, is there any way to work-around this problem ?
  thanks in advance

  Hi Hamed Vaziri,
  
  I have successfully changed the culture of RadScheduler for Winforms to Persian with the latest version of our controls:
  
             CultureInfo info = new CultureInfo("fa-Ir");
              this.radScheduler.Culture = info;
  
  Could you please try the above code and if there's a problem, please give us more detailed explanation about this issue?
  
  I am looking forward to your reply.
  
  

  All the best,

  Sorry for bringing up old posts. Just found this topic while trying to integrate Persian calendar with RadScheduler.
  
  MSDN states about PersianCalendar:
  

  "Applications use a PersianCalendar object to calculate dates in the Persian calendar or convert Persian dates to and from Gregorian dates.

  Your application should not use a PersianCalendar object as the default calendar for a culture. The default calendar is specified by the CultureInfo.Calendar property and must be one of the calendars returned by the CultureInfo.OptionalCalendars property. Currently, the PersianCalendar class is not an optional calendar for any culture supported by the CultureInfo class and consequently cannot be a default calendar." (Source: http://msdn.microsoft.com/en-us/library/system.globalization.persiancalendar.aspx)
  
  So while there is in fact a PersianCalendar in .NET framework, it cannot be used as a default calendar for any CultureInfo. Not yet at least. As to your proposed solution, the "fa-IR" or "fa" cultures use Georgian calendar, and they also have wrong translations for week days (thanks to Microsoft).
  
  I think the best solution would be to use the default Georgian calendar for all the business logic and storage layer, but to change the presentation layer by converting Georgian dates to Persian using PersianCalendar class and changing every textbox or other control that is displaying dates, day of the week and month names.
