classType
The type of the class that is declaring class handling.
routedEvent
The routed event identifier of the event to handle.

A reference to the class handler implementation.
handledEventsToo
True to invoke this class handler even if arguments of the routed event have been marked as handled; false to retain the default behavior of not invoking the handler on any marked-handled event.
RegisterRoutedEvent(string, RoutingStrategy, Type, Type)
Registers a new routed event with the event system.
Declaration
public static RoutedEvent RegisterRoutedEvent(string name, RoutingStrategy routingStrategy, Type handlerType, Type ownerType)Parameters
name
The name of the routed event. The name must be unique within the owner type and cannot be null (Nothing in Visual Basic) or an empty string.
routingStrategy
The routing strategy of the event as a value of the enumeration.
handlerType
The type of the event handler. This must be a delegate type and cannot be null (Nothing in Visual Basic).
ownerType
The owner class type of the routed event. This cannot be null (Nothing in Visual Basic).
Returns
The identifier for the newly registered routed event. This identifier object can now be stored as a static field in a class and then used as a parameter for methods that attach handlers to the event. The routed event identifier is also used for other event system APIs.
