Silverlight DatePicker - SelectedDateFormat ignore culture settings

by dsoltesz 2. February 2010 21:38 >

In my silverlight app I wanted my datepicker controls to always format dates to M/dd/yyyy date format strings regardless of the current users culture setting.

First I change my regional setting to be English(Ireland) and when I run my app, the datepicker will default to that cultures date format off dd/MM/yyyy

but this isn't what I want, I want it to be M/dd/yyyy. 

This can easliy be changed by adding some code to your app.xaml file

public App()


            //force dates to always be M/dd/yyyy regardless of culture

            Thread.CurrentThread.CurrentCulture = (CultureInfo) Thread.CurrentThread.CurrentCulture.Clone();

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

            Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortTimePattern = "h:mm tt";



 Now when you run your app, even though your regional settings are set to English (Ireland) the datepicker still has the selecteddateformat of M/dd/yyyyy
