title: Getting date from DatePicker in format yyyy/MM/dd
body: <p>I have a WPF C# application (.NET 4.0) and I have a date picker. I would like to know if I can change the format date (the text property of the date picker) to the <code>yyyy/MM/dd</code> format.</p>
  
  <p>I am using the MVVM pattern, so I would like to know the XAML code, if it is possible to do it in this place.</p>
