public function Update()

Remarks

The Update method executes any pending requests for painting.

There are two ways to repaint a form and its contents:

• You can use the Invalidate method with the Update method.

• You can call the Refresh method, which forces the control to redraw itself and all its children. This is equivalent to setting the Invalidate method to true and using it with Update.

The Invalidate method governs what is painted or repainted. The Update method governs when the painting or repainting occurs. The Update method just forces the control to be painted immediately, but the Invalidate method governs what is painted when you call the Update method.

.NET Framework Security

• Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see Using Libraries from Partially Trusted Code.
