Beyond these OnXXX() methods, here are a few other methods to be aware of:

• Hide(): Hides the control and sets the Visible property to false

• Show(): Shows the control and sets the Visible property to true

• Invalidate(): Forces the control to redraw itself by sending a Paint event (more information

on graphical rendering in the section “Rendering Graphical Data Using GDI+” later in this

chapter).

The Functionality of the Form Class

The Form class is typically (but not necessarily) the direct base class for your custom Form types.

In addition to the large set of members inherited from the Control, ScrollableControl, and

ContainerControl classes, the Form type adds additional functionality in particular to main win-

dows, MDI child windows, and dialog boxes. Let’s start with the core properties in Table 27-5.
