Silverlight UI culture

I have a date column in a datagrid in my silverlight App. I need the time to be displayed in 24 hr format. To achieve this I have modified the UI culture in Application_Startup event like this:

    CultureInfo cinf = Thread.CurrentThread.CurrentUICulture.Clone() as CultureInfo;
    DateTimeFormatInfo f = cinf.DateTimeFormat.Clone() as DateTimeFormatInfo;
    System.Globalization.DateTimeFormatInfo df = new System.Globalization.DateTimeFormatInfo();
    string format = "MM/dd/yyyy HH:mm:ss";
    f.FullDateTimePattern = format;
    cinf.DateTimeFormat = f;
    Thread.CurrentThread.CurrentUICulture = cinf;

But the UI always picks up the datatime format specified in my regional settings on my OS. Any pointers?

Would it not be better to define ther required formatting on the binding itself? Something like:-

<sdk:DataGridTextColumn Header="SomeDate" Binding="{Binding SomeDate, StringFormat={}{0:MM/dd/yyyy HH:mm:ss}}" />

The reason why your code doesn't work is that the CultureInfo used by controls loaded by Xaml is defined by the Language property of control loading the Xaml. I don't think there is a way to provide a custom CultureInfo in this scenario.

Try setting CurrentCulture as well, that is:

Thread.CurrentThread.CurrentCulture = cinf;
