When you create a delegate, you identify the method that handles the event. To associate the event with your event handler, add an instance of the delegate to the event. Unless you remove the delegate, the event handler is called whenever the event occurs. Multiple delegates can be added to handle an event. For more information about event-handler delegates, see NIB: Events and Delegates.

Handlers are added and removed using the following code. This code example is part of the Send E-mail SDK sample and is from the SendMailActivity.cs file. For more information, see Send E-mail Activity Sample.
