Date format in silverlight DatePicker

In App.xaml.cs, add;

CultureInfo ci = new CultureInfo(Thread.CurrentThread.CurrentCulture.Name);

ci.DateTimeFormat.ShortDatePattern = "dd-MM-yyyy";

Thread.CurrentThread.CurrentCulture = ci;

It will be like this;

public App()

        {

            this.Startup += this.Application_Startup;

            this.Exit += this.Application_Exit;

            this.UnhandledException += this.Application_UnhandledException;

            CultureInfo ci = new CultureInfo(Thread.CurrentThread.CurrentCulture.Name);

            ci.DateTimeFormat.ShortDatePattern = "dd-MM-yyyy";

            Thread.CurrentThread.CurrentCulture = ci;

            InitializeComponent();

        }
