Using the ImageButton Class

As discussed in the In Depth section of this chapter, you can use image button controls to display images that also can handle click events. This is particularly useful if you want to create image maps—those clickable images that initiate various actions depending on where you click them. Image buttons are supported with the ImageButton class; here is the inheritance hierarchy of this class:

Object
   Control
      WebControl
         Image
            ImageButton

You can find the notable public properties of ImageButton objects in Table 17.2, and the notable public events in Table 17.3. (This class has no non-inherited methods.) Note that as with other Web server controls, I am not listing the notable properties, methods, and events this class inherits from the Control and WebControl classes—you can find them in Chapter 15, Tables 15.1 to 15.5. This class also inherits the Image class; you can find the public properties of the Image class in Table 17.1.
