Activity.Canceling Event

Occurs when the activity execution is canceled.

Namespace: System.Workflow.ComponentModel
Assembly: System.Workflow.ComponentModel (in system.workflow.componentmodel.dll)

public event EventHandler<ActivityExecutionStatusChangedEventArgs> Canceling
/** @event */
public void add_Canceling (EventHandler<ActivityExecutionStatusChangedEventArgs> value)

/** @event */
public void remove_Canceling (EventHandler<ActivityExecutionStatusChangedEventArgs> value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.

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

The Cancel 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 Consuming Events.

Notes to Inheritors: When overriding Canceling in a derived class, make sure to call the base class Cancel method so that registered delegates receive the event.
