Classes using ImageMapAreaSelectedEventArgs
The ImageMapAreaSelectedEventArgs class is linked from the ImageMapControl class. If the ImageMapControl is clicked, the control searches for an ImageMapArea at the clicked position. If such an area was found and the AutoNavigate property is set to false, it will raise an AreaSelected and pass a reference to the selected ImageMapArea object.
