How to change culture to a DateTimepicker or calendar control in .Net

Question

how to set internationalization to a DateTimepicker or Calendar WinForm control in .Net when the desire culture is different to the one installed in the PC?

Answer 1

For DateTimePicker

dtp.Format = DateTimePickerFormat.Custom;
dtp.CustomFormat = "yyyy-MM-dd"; // or the format you prefer

Answer 2

It doesn't seem to be possible to change the culture. See this KB article.

Answer 3

System.Threading.Thread.CurrentThread.CurrentCulture = System.Globalization.CultureInfo.CreateSpecificCulture("fr");
System.Threading.Thread.CurrentThread.CurrentUICulture = System.Threading.Thread.CurrentThread.CurrentCulture;

Answer 4

I think there is detour.

1. set event handler "ValueChanged"

2. code

   dateTimePicker.Format = DateTimePickerFormat.Custom;
   string[] formats = dateTimePicker.Value.GetDateTimeFormats(Application.CurrentCulture);
   dateTimePicker.CustomFormat = formats[0];
   

Answer 5

Based on previous solution, I think the better is:

dateTimePicker.Format = DateTimePickerFormat.Custom;
dateTimePicker.CustomFormat = Application.CurrentCulture.DateTimeFormat.ShortDatePattern;
