[System.ComponentModel.Browsable(false)]

[<System.ComponentModel.Browsable(false)>]
member this.StatusChanged : EventHandler<System.Workflow.ComponentModel.ActivityExecutionStatusChangedEventArgs>
Public Custom Event StatusChanged As EventHandler(Of ActivityExecutionStatusChangedEventArgs)
- Attributes
Raising an event invokes the event handler through a delegate.
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.
For more information about handling events, see Handling and Raising Events.
หมายเหตุ
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).
When overriding StatusChanged in a derived class, make sure to call the base class StatusChanged method so that registered delegates receive the event.
