Ovako piše i MSDN-u.
Code:
public void CreateMyDateTimePicker()
{
// Create a new DateTimePicker control and initialize it.
DateTimePicker dateTimePicker1 = new DateTimePicker();
// Set the MinDate and MaxDate.
dateTimePicker1.MinDate = new DateTime(1985, 6, 20);
dateTimePicker1.MaxDate = DateTime.Today;
// Set the CustomFormat string.
dateTimePicker1.CustomFormat = "MMMM dd, yyyy - dddd";
dateTimePicker1.Format = DateTimePickerFormat.Custom;
// Show the CheckBox and display the control as an up-down control.
dateTimePicker1.ShowCheckBox = true;
dateTimePicker1.ShowUpDown = true;
}
I, po tome sudeći tvoja prva tvrdnja pada u vodu. Dakle, moguće je podesiti format datuma.
