Gets a value that becomes the return value of IsEnabled in derived classes.
Assembly: PresentationCore (in PresentationCore.dll)
is introduced in the .NET Framework version 3.5. For more information, see .NET Framework Versions and Dependencies.Notes to Inheritors
The default implementation of this property caches the value and also calculates whether the parent element of this element is enabled. (If the parent is not enabled, the child element cannot be effectively enabled in practical user interface (UI).) If you choose to override this implementation, make certain that you call the base implementation to preserve this behavior.
