Syntax

public class RadElementPropertyMetadata : RadPropertyMetadata
Remarks

This class extends RadPropertyMetadata to provide element-specific property metadata that controls how property changes affect layout, rendering, and inheritance within the element hierarchy. The metadata includes options for invalidating layout, affecting measurements, controlling inheritance, and determining what aspects of the element tree need to be updated when property values change.
