PropertyMetadata.OnApply Method (DependencyProperty, Type)

 

Called when this metadata has been applied to a property, which indicates that the metadata is being sealed.

Namespace:   System.Windows
Assembly:  WindowsBase (in WindowsBase.dll)

abstract OnApply : 
        dp:DependencyProperty *
        targetType:Type -> unit
override OnApply : 
        dp:DependencyProperty *
        targetType:Type -> unit

Parameters

dp
Type: System.Windows.DependencyProperty

The dependency property to which the metadata has been applied.

targetType
Type: System.Type

The type associated with this metadata if this is type-specific metadata. If this is default metadata, this value is a null reference.

Subclasses should assure that any mutability of the data structure of a PropertyMetadata subclass should be marked as immutable once OnApply is called. This will be called once the metadata is applied to a property system operation (register, add owner, override metadata).
