What would this code look like if you could take INotify Property Changed out of the picture?What if data binding could work directly against a property and update whenever it changed?Button has a tiny empty tooltip: This code seemed perfectly fine for me so it took me a lot of time to google the answer.
The value of that property depends upon properties of other objects, and so the dependent object registers for the Property Changed event.
When this event is fired, the dependent object calculates the value of the dependent property, stores it, and fires another Property Changed event upstream. Much of the code using INotify Property Changed is concerned with registering for the Property Changed event, reregistering when the subject changes, and firing it at the appropriate time.
To use Update Controls, add two references to your C# or Visual Basic WPF project: Update and Update Controls. Within your XAML files, add a namespace reference to Update Controls. Mail Merge is an example of a dependent property because it depends upon other properties for its value.
Current Customer and Name, on the other hand, are independent properties since they can change independently.
He codes in both C# and Java, and applies the lessons learned from each to the other.
