Error happened when a date or time is selected from the calendar.
I need to initialize the CultureInfo because I need to control the displayed DateTime format.

Your help is much apprepciated.

Hi Edwin,

In your custom DateTimeFormat you are using a DateSeparator (space), which is different from the default one for the current culture (slash). You should set the DateSeparator explicitly:

cultureInfo.DateTimeFormat.ShortDatePattern = "dd MMM yy";
cultureInfo.DateTimeFormat.DateSeparator = " ";


Kind regards,
