Custom Control Painting and Rendering
Custom painting of controls is one of the many complicated tasks made easy by the .NET Framework. When authoring a custom control, you have many options regarding your control's graphical appearance. If you are authoring a control that inherits from the Control, you must provide code that allows your control to render its graphical representation. If you are creating a user control by inheriting from the UserControl, or are inheriting from one of the Windows Forms controls, you may override the standard graphical representation and provide your own graphics code. If you want to provide custom rendering for the constituent controls of a UserControl you are authoring, your options become more limited, but still allow a wide range of graphical possibilities for your controls and applications.
