Activity.StatusChanged Event

Occurs when the ActivityExecutionStatus of a running Activity changes.

Namespace:  System.Workflow.ComponentModel
Assembly:  System.Workflow.ComponentModel (in System.Workflow.ComponentModel.dll)

[BrowsableAttribute(false)]
public event EventHandler<ActivityExecutionStatusChangedEventArgs> StatusChanged

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The StatusChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

NoteNote

When an activity (Activity A) subscribes to a different activity's (Activity B) StatusChanged event, the Activity property of the associated ActivityExecutionStatusChangedEventArgs refers to the activity subscribed to (Activity B), and the associated Sender object refers to the execution context of the subscribing activity (Activity A).

Notes to Inheritors

When overriding StatusChanged in a derived class, make sure to call the base class StatusChanged method so that registered delegates receive the event.
