Fill Gradient. Gradient specifies the colors used to fill a zone.
The zone is filled using these three colors: StartColor, MidColor and EndColor. You can control the drawing output by setting Gradient.Direction. Use the Visible property to show / hide filling. Default value: null
Use invalidate when the entire canvas needs to be repainted.
When more than one region within the canvas needs repainting, Invalidate will cause the entire window to be repainted in a single pass, aing flicker caused by redundant repaints. There is no performance penalty for calling Invalidate multiple times before the control is actually repainted.
