Hello Amin,

Thank you for writing.

Currently, RadCalendar does not support persian calendar. We have a feature request for such in our Feedback Portal. Feel free to add your vote and subscribe for status change alerts here: http://feedback.telerik.com/Project/154/Feedback/Details/111912.

For now, you can set the calendar Culture to "fa-IR" to get proper localization as discussed in this thread.

I hope that you find this information useful.  

Regards,

Hello there,

it would be great if you can help me on it .

Hello ,

Thank you for writing.

Yes, this is supported now and to enable this functionality you should only change the culture of the control. More information is available in the following articles:

• CultureInfo and RegionInfo Basics
• Globalization Properties

Let me know if you have additional questions.
