Using the <i class="emphasis">LinkButton</i> Class

Using the LinkButton Class

As discussed in the In Depth section of this chapter, link buttons look like standard hyperlinks, but actually work like buttons, letting you handle them in Visual Basic code. Link buttons are supported with the LinkButton class; here's the inheritance hierarchy for this class:

Object
   Control
      WebControl
         LinkButton

You can find the notable public properties of LinkButton objects in Table 17.7, and their notable public events in Table 17.8. (This class has no non-inherited methods.) Note that as with other Web server controls, I am not listing the no-table 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.
