Hi,

In my program, I try override default value of NumberSubstitution.SubstitutionProperty for FrameworkElement, But i get this error:

{"PropertyMetadata is already registered for type 'FrameworkElement'."}

and my code here:

C#

NumberSubstitution.SubstitutionProperty.OverrideMetadata(typeof (FrameworkElement),
    new PropertyMetadata(NumberSubstitutionMethod.Traditional));

How can i override default value of NumberSubstitution.SubstitutionProperty ?

Thanks :)

"Override a value" is nonsense. There is no such concept. You never override values, only the virtual methods or properties. Why would you need to "override" this value and what it would mean?

Default value of NumberSubstitution.SubstitutionProperty is NumberSubstitutionMethod.AsCalture, and when i change DefaultThreadCurrentCulture and DefaultThreadCurrentUICulture of my application, for example to "fa-IR", on FlowDirection.LeftToRight WPF reject my calture NumberFormat unless in ui controls i set NumberSubstitution.SubstitutionProperty to NumberSubstitutionMethod.Traditional. i want to set this one time for all and dont want use Styles for this purpose
