PropertyMetadata.OnApply Method

.NET Framework 4.5

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)

protected virtual void OnApply(
	DependencyProperty dp,
	Type targetType
)

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.

Remarks

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).
