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

Based on previous solution, I think the better is:

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

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

    That will not change the regional settings of the Windows, only the current UI culture and current culture of the current thread (as the properties' names suggest). But DateTimePicker control looks only for the regional setting of the Windows, so it doesn't matter. – Nenad Dobrilovic Jun 08 '09 at 12:37

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];

    GetDateTimeFormats() does not produce format strings (that can be used to do formatting), but formatted strings (the result of formatting). Assigning such a string to .CustomFormat makes no sense. Would vote down answer, but lacking reputation myself... – Peter B Jul 29 '14 at 14:51

For DateTimePicker

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

    Setting the format is not the only thing controlled by the culture. It controls a lot of other things, such as whether the first day of the week is Sunday or Monday. – Kibbee Oct 28 '08 at 02:56

    Format is used only to show current date, but if you want to choose it, datetimepicker control will show full date, based on the regional settings. – Nenad Dobrilovic Jun 08 '09 at 12:34

Use the telerik radDateTimePicker and write this code , after InitializeComponent(), and Instead of "fa-IR" use your culture.

Application.CurrentCulture = new CultureInfo("fa-IR"); 
radDateTimePicker1.Format = DateTimePickerFormat.Custom;
radDateTimePicker1.CustomFormat = Application.CurrentCulture.DateTimeFormat.ShortDatePattern;
