Question

If I have a base class that implement INotifyPropertyChanged

public class ResourceWrapperBase : INotifyPropertyChanged

Does firing the propertychanged event in the base class, like this:

PropertyChanged(this, new PropertyChangedEventArgs(null)) 

Also update all the bindings on properties in classes that inherit from this base class?

public class ResourceWrapper : ResourceWrapperBase

So in other words, I want to update all bindings to properties in ResourceWrapper when the propertychanged event in ResourceWrapperBase is fired.

Is this possible?

Answer 1

Usually firing PropertyChanged event with PropertyChangedEventArgs(null) causes all bindings to be updated.
