Indicates the routing strategy of a routed event.

Assembly:  PresentationCore (in PresentationCore.dll)

public enum RoutingStrategy

Member nameDescription
Bubble

The routed event uses a bubbling strategy, where the event instance routes upwards through the tree, from event source to root.

Direct

The routed event does not route through an element tree, but does support other routed event capabilities such as class handling, EventTrigger or EventSetter.

Tunnel

The routed event uses a tunneling strategy, where the event instance routes downwards through the tree, from root to source element.

Routing strategy for each routed event must be only one of these values. However, input events often exist in pairs on base classes, where one event is the bubbling version and one event is the tunneling version. For input events uniquely, the tunneling and bubbling versions have shared arguments and are raised in succession in response to the input device condition that raises the events.
