hey everyone,

This bug appears when i go to any module settings when i am in using ar-SA culture. The calendar should be hijri. This bug is really annoying, i am using both dnn 6.1.4 and 6.1.5 and i'm facing it on both versions although the gemini says it's been resolved in 6.1.4.

It seems it appears since the radcalendar or raddatepicer doesn't change the culture correctly on the page load or init. I've tried it in one of my modules and it loaded without the error ( dnn Valid values are between 1318 and 1450, inclusive. Parameter name: year) as you can see in the following snapshot:

The good thing is that the month year is correct the bad thing is that the days are all messed up.

In addition if you click on any of the previous-next-first last- button or you even pick a date, the date is also messed up and incorrect. The following snapshot is when you click on the next for example button:

Anyone out there with a fix, alternative to this datepicker or additional info about this bug???

We can do the same for the page settings available in:

dnndir\DesktopModules\Admin\Tabs\ManageTabs.ascx.cs on page_init

CultureInfo info = new CultureInfo(System.Threading.Thread.CurrentThread.CurrentCulture.ToString());
GregorianCalendar calendar = new GregorianCalendar();
info.DateTimeFormat.Calendar = calendar;
this.datepickerStartDate.Culture = info;
this.datepickerEndDate.Culture = info;
