Causes the control to redraw the invalidated regions within its client area.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Executes any pending requests for painting.
There are two ways to repaint a form and its contents:
You can use one of the overloads of the Invalidate method with the method.
The Invalidate method governs what gets painted or repainted. The method governs when the painting or repainting occurs. If you use the Invalidate and methods together rather than calling Refresh, what gets repainted depends on which overload of Invalidate you use. The method just forces the control to be painted immediately, but the Invalidate method governs what gets painted when you call the method.
