fa-Ir Culture in RadDateTimePicker problem

[Arash]

hello,
I am using Q2 2011 and want to have a Persian DateTimePicker but when I set RadDateTimePicker culture property to fa-Ir, an exception is thrown in this line:

this.radDateTimePicker1.Culture = new System.Globalization.CultureInfo("fa-IR");

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

I tried everything said in other forum threads like setting thread culture and calendar to persian :

CultureInfo info = new CultureInfo("fa-Ir");
info.DateTimeFormat.Calendar = new PersianCalendar();
Thread.CurrentThread.CurrentCulture = info;
this.radDateTimePicker1.Culture = info;

but I get the same exception at this line:

this.radDateTimePicker1.Culture = info;

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Then I tried another code posted in MSDN forums:

System.Globalization.CultureInfo calture = new System.Globalization.CultureInfo("fa-IR");
System.Globalization.DateTimeFormatInfo info = calture.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", "ارديبهشت", "خرداد", "تير", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };
info.MonthNames = new string[] { "فروردین", "ارديبهشت", "خرداد", "تير", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };
info.AMDesignator = "ق.ظ";
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(calture, cal);
typeof(System.Globalization.CultureInfo).GetField("calendar", System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).SetValue(calture, cal);

System.Threading.Thread.CurrentThread.CurrentCulture = calture;
System.Threading.Thread.CurrentThread.CurrentUICulture = calture;
System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat = info;
System.Globalization.CultureInfo.CurrentUICulture.DateTimeFormat = info;

the same exception is thrown again in this line:

this.radDateTimePicker1 = new Telerik.WinControls.UI.RadDateTimePicker();

Hello Arash,

Thank you for writing.

This is a known issue that will be addressed in our upcoming Q3 2011 release. Due to the nature of the issue, I cannot suggest a suitable workaround for it.

Do not hesitate to contact us if you have other questions.

Kind regards,
Peter

Hello Peter and thank you for your support, so it hasn't been solved yet in any available versions and I can't do anything for fixing it myself?

[Peter]

Hi Arash,

I am afraid I cannot suggest a workaround for the issue, because the source of the issue is in the order in which the fields are initialized in RadCalendar.

Greetings,
Peter

In new release Q2 2011 SP1 this problem hasn't been solved?

[Nikolay]

Hello Arash,

Please re-read the response of my colleague Peter given on Oct 28. As he mentions there, the issue will be addressed in Q3 2011 (expected to be release in mid-November). In other words, the issue is not addressed in Q2 2011 SP1.

I hope that this clarifies the case.

Best wishes,
Nikolay

Hi Arash.
I have a solution for your problem:
1- Go to this address  : http://persianculture.codeplex.com/
2- Set your target framework on .net 4 or 3.5

I am using Telerik 2013 with .Net Framework 2.0. The problem is exist. I think it is because of .net framework version. Am I right?

[Peter]

Hello Shabab,

Thank you for contacting us.

I was not able to reproduce the issue using version Q2 2013. Please, refer to the screenshot from my attempts. Please send me a sample project which I can use to reproduce the wrong behavior locally. This will help me investigate the case and provide you with proper support.

In case you have any further questions, do not hesitate to write back.

Regards,
Peter

Hello support!
Is this problem solved in new version?
Thanks

[Stefan]

Hi John,

Thank you for writing.

The issue is already resolved and you can successfully set the RadDateTimePicker.Culture to "fa-IR", and the control will be localized correctly, without an exception. Please have a look at the attached screen shot.

I hope that you find this information useful.

Stefan

[John]

Thanks
But the screen shot is not persian calendar yet!
It is Arabic!
I need to know is it possible to have persian calendar?

[Stefan]

Hi,

Currently, RadCalendar does not support persian calendar. We have a feature request for such in our Public Issue Tracking System. Feel free to add your vote and subscribe for status change alerts here: http://www.telerik.com/support/pits.aspx#/details/Issue=14570.

For the time being, you can only use the Culture property to localize the calendar.

Stefan
