Create a Globalization application in Windows phone 8.

Globalization application

Vipul given good example  Here

Now we need to modified little bit code because of next time onwards application  will be open last time selected language.

Just we need to store selected language in  Isolated storage file like below :-

Make sure your Page has these name spaces

using System.Globalization;
using System.Threading;
using System.IO.IsolatedStorage;

private IsolatedStorageSettings appSettings = IsolatedStorageSettings.ApplicationSettings;
        // Constructor
        public MainPage()
        {
            if (appSettings != null && appSettings.Count >0)
            { 
                ApplyCulture(new CultureInfo((string)appSettings["lan"])); 
            }
            
            InitializeComponent();


           
        }

// this above condition is  next time onwards just check the isolated storage memory  if it has any language then it will open last time selected language.

private void radioButtonenUS_Checked(object sender, RoutedEventArgs e)
        {
            ApplyCulture(new CultureInfo("en-US"));

            appSettings["lan"] = "en-US";
        }

here we save the Selected language in Isolated storage memory .
 
private void radiobuttonfrFR_Checked(object sender, RoutedEventArgs e)
        {
            ApplyCulture(new CultureInfo("fr-FR"));

          appSettings["lan"] = "fr-FR";
            
        }

 private void ApplyCulture(CultureInfo cul)
        {
            Thread.CurrentThread.CurrentCulture = cul;
            Thread.CurrentThread.CurrentUICulture = cul;
            DateTime current = DateTime.Now;
            textBoxLongDate.Text = current.ToString("D");
            textBoxShortDate.Text = current.ToString("d");
            textBoxTime.Text = current.ToString("T");
            textBoxCurrency.Text = 100.ToString("C");
            textBlockLongDate.Text = AppResources.TextLabelLongDate;
            textBlockShortDate.Text = AppResources.TextLabelShortDate;
            textBlockTime.Text = AppResources.TextLabelTime;
            textBlockCurrency.Text = AppResources.TextLabelCurrency;
            textBlockUser.Text = AppResources.UserName;
            textBlockHello.Text = AppResources.Salutation;
        }

 //if we don't write the above method your current page doesn't convert to selected language this is for immediate effect for current page.
