NumberSubstitution.Substitution Property

Gets or sets a value which identifies the substitution method that is used to determine number substitution.

Namespace:  System.Windows.Media
Assembly:  PresentationCore (in PresentationCore.dll)

public NumberSubstitutionMethod Substitution { get; set; }
<object NumberSubstitution.Substitution="NumberSubstitutionMethod"/>

Identifier field


Metadata properties set to true


The default value of the CultureSource property is AsCulture, which specifies that the substitution method should be determined based on the number culture's DigitSubstitution property value.

This reference page represents two identically named but not entirely equivalent usages for the Substitution property:

  • You can set this property in code on a NumberSubstitution instance, as a common language runtime (CLR) property. In this usage, the property is not backed by a dependency property identifier, it is backed by a private field and does not act as a dependency property.

  • You can set this property as an attached property usage in XAML. The attached property usage is the reason why this property has a Dependency Property Information section, because the attached property is backed by a dependency property identifier. In XAML, the usage is <object NumberSubstitution.Substitution="value".../>, where object is an object element where the specified number substitution logic applies, and value is a string representation of a NumberSubstitutionMethod value. In code, the attached property usage is supported by GetSubstitution and SetSubstitution.
