Custom date format in DatePicker in Beta 2.0

Hi all,

I am trying to set my custom date format like dd-MMM-yyyy to datepicker control in silverlight 2 beta 2.

I have tried as following way:

datepicker.SelectedDate = DateTime.Today;

datepicker.Text =  datepicker.SelectedDate.Value.ToString("dd-MMM-yyyy");

on load event of it. But fail to get current date in formate like 13-Nov-2008.

I need help here..

 

Thanks

Pratik

Hi Amanda,

I hope they add a custom formatter property to the DatePicker other than just (Long, Short)

I was not able to use the SelectedDateChanged for formatting because Editing causes changes before Editing is completed.   I tried LostFocus but it continuously looped during my test.   I think it may be a known issue with LostFocus.

Thanks,

John

Hi Amanda, I tried it in Silverlight 2. It did not work. My system date format is "dd-MMM-yyyy" and i am trying to format it in "MM/dd/yyyy" format. This SelectedDateChange event was falling in loop therefore i used CalenderClosed event but no luck. Thanks

 Hi kent,

Hi,

You can try to add the namespace using System.Globalization; using System.Threading; in the app.xaml.cs file, and add below two lines code in the Application_Startup event:

  Thread.CurrentThread.CurrentCulture = new CultureInfo("en-GB");
   Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortDatePattern = "dd-MMM-yyyy";

 for example:

 

 private void Application_Startup(object sender, StartupEventArgs e)
        {
            Thread.CurrentThread.CurrentCulture = new CultureInfo("en-GB");
            Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortDatePattern = "dd-MMM-yyyy";
            this.RootVisual = new Page();
        }

Hi Amanda,

I'm running Silverlight 2.0 and my machine's regional setting date format is set to M/dd/yyyy, when I run the following code, it returns the correct format in Silverlight as I specify.

Thread.CurrentThread.CurrentCulture = new CultureInfo("en-us");

Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortDatePattern = "dd-MMM-yyyy";

 However, when I change my machine's regional setting date format to M-dd-yyyy and run the following code, it does not returns the correct format as I specify.

Thread.CurrentThread.CurrentCulture = new CultureInfo("en-us");

Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortDatePattern = "dd/MMM/yyyy";

Instead, it returns 09-Mar-2009 and looks like it still use the Date Separator from regional settings.  Did I do anything wrong here?  Or is it a bug in Silverlight 2.0?

Thanks

David

I've found the answer why setting the ShortDatePattern = "dd/MMM/yyyy" does not work.  It turns out that it needs to have the escape character "\" the for slash "/" in the format string.  Once I change to the following, it works

Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortDatePattern = "dd\/MMM\/yyyy";

 Thanks

David

 Addition to above and making it working

 public App()
        {
            this.Startup += this.Application_Startup;
            this.Exit += this.Application_Exit;
            this.UnhandledException += this.Application_UnhandledException;
            Thread.CurrentThread.CurrentCulture = (CultureInfo)Thread.CurrentThread.CurrentCulture.Clone();
            Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortDatePattern = "dd/MM/yyyy";

            InitializeComponent();
        }

 

public UserControl1()
        {
            // Required to initialize variables
            InitializeComponent();
            dt.Loaded += new RoutedEventHandler(dt_Loaded);
            dt.SelectedDateChanged += new EventHandler<SelectionChangedEventArgs>(dt_SelectedDateChanged);
        }

        void dt_SelectedDateChanged(object sender, SelectionChangedEventArgs e)
        {
            this.dt.Text = this.dt.SelectedDate.Value.ToString("dd-MM-yyyy");
        }

        void dt_Loaded(object sender, RoutedEventArgs e)
        {
            this.dt.Text = DateTime.Now.ToString("dd-MM-yyyy");
        }

Add this in app.xaml.cs. 

CultureInfo ci = new CultureInfo(Thread.CurrentThread.CurrentCulture.Name);
            ci.DateTimeFormat.ShortDatePattern = "dd/MM/yyyy";
                 Thread.CurrentThread.CurrentCulture = ci;

Make sure that you add two namespaces

1. using System.Threading

2.Using System.globalization

It worked for me. could take a breather.....

Mark it as an answer if it server. :)
