Button.OnClick Method

This override notifies the Silverlight automation infrastructure to raise the click event. Raising an event invokes the event handler through a delegate. The OnClick 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.

When overriding OnClick in a derived class, be sure to call the base class’s OnClick method so that registered delegates receive the event.
