How to change format (e.g. dd/MMM/yyyy) of DateTimePicker in WPF application

Question

I want to Change the Format of date selected in DateTimePicker in WPF Application

Answer 1

Typically the date time format is stored in a resource file, because this would help in internationalization of the app.

You can pick up the format from the resource file & use a ToString(DATE_FORMAT)

in your case you might want to use

dateTimePicker.SelectedDate.ToString("dd-MMM-yyyy");

Answer 2

dateTimePicker.SelectedDate.ToString("dd-MMM-yyyy"); this will return the string but not the date format in datepicker? how to do that?

Answer 3

In XAML:

<toolkit:DatePicker SelectedDateFormat="Long" />

or

<toolkit:DatePicker SelectedDateFormat="Short" />

Answer 4

DatePicker1.SelectedDate = DatePicker1.SelectedDate.Value.ToString("dd/MM/yyyy")
