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

Using the HtmlSelect Class

This class gives you access to HTML <select> elements in server code. Here is the inheritance hierarchy of this class:

Object
   Control
      HtmlControl
         HtmlContainerControl
            HtmlSelect

You can find the notable public properties of HtmlSelect objects in Table 19.18 and their events in Table 19.19. (This class has no non-inherited methods.) Note that as with other HTML server controls, I am not listing the notable properties, methods, and events this class inherits from the Control class; you can find them in Tables 15.1 to 15.3 in Chapter 15. This class also inherits the HtmlControl class—you can find that class in Table 19.2—and the HtmlContainerControl class, which you see in Table 19.3.
