Immediate Solutions: Using the CheckBox Class

Checkboxes display checkmarks that allow the user to toggle a True or False condition. Here is the class hierarchy of the CheckBox class:

Object
   Control
      WebControl
         CheckBox

You can find the notable public properties of CheckBox objects in Table 16.1, the notable public methods in Table 16.2, and the notable public events in Table 16.3. 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.
