The Button.Click event is raised when the System.Web.UI.WebControls.Button control is clicked. This event is commonly used when no command name is associated with the System.Web.UI.WebControls.Button control (for instance, with a Submit button).

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

The Button.OnClick(EventArgs) 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.
