The event is raised when the Button control is clicked. This event is commonly used when a command name, such as Sort, is associated with the Button control. This allows you to create multiple Button controls on a Web page and programmatically determine which Button control is clicked.
The event is raised through the control hierarchy in the form of the BubbleEvent.
