Is CanExecuteChanged a event property of ICommand

Question

Is CanExecuteChanged a event property of ICommand? If it's a property why does it have a add and remove instead of get , set?

If , it's not a property , then what is it?

 public event EventHandler CanExecuteChanged
        {
            add { CommandManager.RequerySuggested += value; }
            remove { CommandManager.RequerySuggested -= value; }
        }

And when does CanExecuteChanged gets fired?

It's an event. Says so right there on the title. http://msdn.microsoft.com/en-us/library/system.windows.input.icommand.canexecutechanged.aspx — Jon, Apr 04 '13 at 08:58

CanExecuteChanged is an event as indicated by the key word. You can read something about it here. The syntax of its accessor declaration is only similar to the implementation of a property.

It is an Event and does get fired if CanExecute method changes.

There are other questions here on SO like this and this that might be interesting for you.
