RoutingStrategy Enumeration

Indicates the routing strategy of a routed event.

Namespace:  System.Windows
Assembly:  PresentationCore (in PresentationCore.dll)

'Declaration
Public Enumeration RoutingStrategy
<object property="enumerationMemberName" .../>

Member nameDescription
BubbleThe routed event uses a bubbling strategy, where the event instance routes upwards through the tree, from event source to root.
DirectThe routed event does not route through an element tree, but does support other routed event capabilities such as class handling, EventTrigger or EventSetter.
TunnelThe 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.
