I am assuming that you don't really mean "field" but you mean "property". If this is the case, the simplest way I can think of right now would be to override the "OnPropertyChanged" method in your business object as follows:

        protected override void OnPropertyChanged(string propertyName)

        {

            base.OnPropertyChanged(propertyName);

            Console.WriteLine("Hello from property " + propertyName);

        }
