Hi,

I'm currently using RadControls for ASP.NET AJAX Q2 2009 NET35. I can make RadCalendar with GregorianCalendar and Arabic language working, but somehow the RadDatePicker is not showing when I use the same method.

Below is my code, very simple, only using 1 RadCalendar and 1 RadDatePicker and two buttons to switch between language. After switch to arabic, the RadDatePicker didn't work at all.

I need to use arabic month name and day name, but I want the calendar dates to be in Gregorian format, not hijri format. Do I need to change javascript code too? Or just the code-behind?

Hello Omar,

I checked the sample project you sent me but I could not replicate the issue you described. I am attaching screenshots of what I saw. Please, tell me if I am missing something out. Is there a specific way to trigger the erroneous behavior?

Dear Tsvetina,

Sorry, it seems to be issue with IE 8 on Windows 7 64x, when I changed browser it worked fine. The RadDatePicker calendar position is overlapping with the previous RadCalendar on the top of it.

Anyway, I found a way to fix this issue in the quick way, to set all the RadCalendar and RadDatePicker in the solution to always use Gregorian Calendar can be done with this code:

                    Thread.CurrentThread.CurrentCulture.DateTimeFormat.Calendar = new GregorianCalendar();         
            Thread.CurrentThread.CurrentUICulture.DateTimeFormat.Calendar = new GregorianCalendar();         

This way, no matter what the language culture, the calendar will be in GregorianCalendar format. Hope this info can be helpful for anyone who stumble upon this problem too.

Cheers,
