Enum PropagationPhase

The propagation phases of an event.

public enum PropagationPhase : int

When an element receives an event, the event propagates from the panel's root element to the target element.

In the TrickleDown phase, the event is sent from the panel's root element to the target element's parent.

In the AtTarget phase, the event is sent to the target element.

In the BubbleUp phase, the event is sent from the target element's parent back to the panel's root element.

In the last phase, the DefaultAction phase, the event is resent to the target element.

Name	Description	Value
AtTarget	The event is sent to the target.
BubbleUp	The event is sent from the target element's parent back to the panel's root element.
DefaultAction	The event is sent to the target element, which can then execute its final default actions for the event. Event handlers do not receive the event in this phase. Instead, ExecuteDefaultAction is called on the target element.
DefaultActionAtTarget	The event is sent to the target element, which can then execute its default actions for the event at the target phase. Event handlers do not receive the event in this phase. Instead, ExecuteDefaultActionAtTarget is called on the target element.
None	The event is not propagated.
TrickleDown	The event is sent from the panel's root element to the target element's parent.
