In silverlight, how to you attach a changeEvent handler to an inherited dependency property?

Question

How would you attach a propertychanged callback to a property that is inherited? Like such:

class A {
  DependencyProperty prop;
}

class B : A {
   //...
   prop.AddListener(PropertyChangeCallback);
}

Answer 1

(edited to remove recommendation to use DependencyPropertyDescriptor, which is not available in Silverlight)

PropertyDescriptor AddValueChanged Alternative

Answer 2

@Jon That was the first solution I found, unfortunately it looks like there is no DependencyPropertyDescriptor in Silverlight.

Answer 3

Have you tried a two way data binding between the two dependency properties?

Answer 4

@MojoFilter,

Jon's last suggestion link will give you what you're looking for: it uses weak references to register listening to changes by wrapping properties in a new object. Scroll to the bottom of "PropertyDescriptor AddValueChanged Alternative". You'll have to change the Binding code around a bit since BindingOperations doesn't exist.
