PropertyMetadata::OnApply Method (DependencyProperty^, Type^)
.NET Framework (current version)
Called when this metadata has been applied to a property, which indicates that the metadata is being sealed.
Assembly: WindowsBase (in WindowsBase.dll)
Parameters

System.Windows::DependencyProperty^
The dependency property to which the metadata has been applied.

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).
