RadzenDatePicker localization

I am about to localize my application and so far so good but RadzenDatePicker is something that I could not localize day names and month names. I found some posts in this forum about this topic and tried to implement them with no luck.
I set in my Program.cs default culturalInfo and culturalUIInfo and checked if it is set right by following code

var cC = CultureInfo.CurrentCulture.Name;
var cUIC = CultureInfo.CurrentUICulture.Name;

but days and months in application did not change.
Where did I go wrong?

You probably didn't set the current culture properly. Can't tell more as we lack the rest of the context. In any case every component has a Culture property which you can set too.

Your answer explains everything to me.

Thank you.
