.NET Windows Forms in a Nutshell

Name

PaintEventArgs

Synopsis

This class encapsulates the data used by the Control.Paint event, raised when the Control needs repainting.

You can retrieve the System.Drawing.Graphics surface on which to draw and the ClipRectangle that needs repainting (to optimize your paint function).

Information about repaint is also included under Control and ControlStyles.
