    public static RoutedEvent[] GetRoutedEventsForOwner(Type ownerType)
    Parameters

    System.Type ownerType

    The type to start the search with. Base classes are included in the search.
    Returns
    Type Description
    RoutedEvent[]

    An array of matching routed event identifiers if any match is found; otherwise, null.

    RegisterClassHandler<T>(Type, RoutedEvent<T>, EventHandler<T>, Boolean)

    Registers a class handler for a particular routed event, with the option to handle events where event data is already marked handled.

    public static void RegisterClassHandler<T>(Type classType, RoutedEvent<T> routedEvent, EventHandler<T> handler, bool handledEventsToo = false)
    where T : RoutedEventArgs
    Parameters
    Type Name Description
    System.Type classType

    The type of the class that is declaring class handling.
    RoutedEvent<T> routedEvent

    The routed event identifier of the event to handle.
    System.EventHandler<T> handler

    A reference to the class handler implementation.
    System.Boolean 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.
    Type Parameters
    Name Description
    T
    Exceptions
    Type Condition
    System.ArgumentNullException

    classType, routedEvent, or handler is null.

    RegisterRoutedEvent<T>(String, RoutingStrategy, Type)

    Registers a new routed event.

    public static RoutedEvent<T> RegisterRoutedEvent<T>(string name, RoutingStrategy routingStrategy, Type ownerType)
    where T : RoutedEventArgs
    Parameters
    Type Name Description
    System.String name

    The name of the routed event. The name must be unique within the owner type (base class included) and cannot be null or an empty string.
    RoutingStrategy routingStrategy

    System.Type ownerType

    The owner class type of the routed event. This cannot be null.
    Returns
    Type Description
    RoutedEvent<T>

    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.
    Type Parameters

    T
    Exceptions
    Type Condition
    System.ArgumentNullException

    name or ownerType is null.
    System.InvalidOperationException
