If you want to specify your own format, you can create different format strings in your localization resource files and bind to StringFormat
Text="{Binding MyProperty.CreateDate, StringFormat={StaticResource shorDateFormatString}}"
Alternatively, set the date text in the codebehind, with some custom logic to see whether the month or the day comes first in the local convention
string shortDatePattern = CultureInfo.CurrentCulture.DateTimeFormat.ShortDatePattern
if(shortDatePattern.indexOf("dd") < shortDatePattern.indexOf("MM"))
dateLabel.Text = MyProperty.CreateDate.toString("dd.MM")
else
dateLabel.Text = MyProperty.CreateDate.toString("dd.MM")
