Description
Occurs when the control is redrawn.
OnPaint also occurs when DoPaint is called.
Write an event handler for OnPaint to change the way the control renders itself.
Tip: Notice that calling BeginScene in the OnPaint event handlers has no effect, because BeginScene is called before the OnPaint event handler runs. This guarantees that painting always occurs in OnPaint without requiring extra and probably unexpected code to allow drawing to have an effect.
