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
.
