CancelEventHandler
Delegate
Definition
Represents the method that handles a cancelable event.
public delegate void CancelEventHandler(object sender, CancelEventArgs e);
Parameters
- sender
The source of the event.
- e
A CancelEventArgs that contains the event data.
- Inheritance
Examples
For an example of how to use the CancelEventHandler delegate, please see the sample code in the CancelEventArgs class.
Remarks
When you create a CancelEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event-handler method is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see NIB: Events and Delegates.
