Remarks

The Click event is raised when the LinkButton control is clicked. This event is commonly used when no command name is associated with the LinkButton control, as in the case of a Submit button.

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

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.

Notes to Inheritors

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