There is a string format property available when you are declaring the binding:

<TextBox Text="{Binding Path=DateTimeValue, StringFormat=dd-MM-yyyy}" />

(You need to be on .NET 3.5 SP1 for this property to exist)

If you want to use a common format string between bindings, you could declare the binding like this:

<Textbox Text={Binding Path=DateTimeValue, StringFormat={x:Static local:Constants.DateTimeUiFormat}} />

With your constants class like this:

public static class Constants
{
    public const string DateTimeUiFormat = "dd/MM/yyyy";

    //etc...
}

Thanks Brian! I used this in combination with `System.Threading.Thread.CurrentThread.CurrentUICulture.DateTimeFormat.ShortDatePattern` to get an i18n short date. – Ben Jan 10 '19 at 23:30

May be helpful to someone:

<TextBlock Text="{Binding Source={x:Static sys:DateTime.Now},
           StringFormat='{}{0: Today is dddd, MMMM dd, yyyy, hh:mm:ss}'}"/>

or 24h and 2digits month and year format:

<TextBlock Text="{Binding Source={x:Static sys:DateTime.Now},
           StringFormat='{}{0: Today is dddd, MM.dd.yy, HH:mm:ss}'}"/>
