Creating Routed Events

Unfortunately, Visual Studio doesn’t include a snippet for creating routed events (probably because you’ll do it a lot less frequently). But the steps are similar to creating a dependency property, which you already know how to do, and none is particularly difficult. Here’s the process in detail:

1 CREATE THE EVENTARGS CLASS, IF NECESSARY

Many events can use RoutedEventArgs or one of its descendants, but if you need to pass additional information to the methods that respond to your events, you’ll need to create your own argument class. The class can be defined independently or nested within the class that declares the event, which is convenient if you won’t be using it elsewhere. In either case, the class should be public.
