RelativeSource.ShouldSerializeAncestorLevel Method ()
Indicates whether the AncestorLevel property should be persisted.
Assembly: PresentationFramework (in PresentationFramework.dll)
This ShouldSerialize method is provided because the AncestorLevel property does not have a simple default value. This method indicates whether the property has changed from its default value. You typically invoke this method if you are either developing a designer for the RelativeSource or developing your own control incorporating the RelativeSource.
