Examples
ImageButton
In this example we declare one ImageButton
control and one Label control in an .aspx file. When the user clicks on the image, the
getCoordinates subroutine is executed. The subroutine sends the message
"Coordinates: " and the x and y coordinates of the click to the Label control.
