ASP.NET in a Nutshell

Name

ImageButton

Synopsis

This class extends the Image class to provide an image control that can respond to button clicks. The ImageButton class provides both a Click and a Command event, which will fire when the image is clicked. Use the Command event and the CommandName property to specify additional information that will be provided to the event handler. This technique is sometimes used to allow the same event handler to respond to clicks from multiple ImageButton controls and determine what control fired the event.

By default, clicking an ImageButton control will cause page validation to occur. To change this behavior, set the CausesValidation property to False.
