Property Value

Type: SystemBoolean
true if the surface of the control should be drawn using double buffering; otherwise, false.

Buffered graphics can reduce or eliminate flicker that is caused by progressive redrawing of parts of a displayed surface. Buffered graphics require that the updated graphics data is first written to a buffer. The data in the graphics buffer is then quickly written to displayed surface memory. The relatively quick switch of the displayed graphics memory typically reduces the flicker that can otherwise occur.


DoubleBuffered is not a bindable property.
