In the underlying Win32 API (the way it was done before GDI+), the client area of a window is painted by a call to BitBlt (or similar function), and then Invalidate, and finally Update.
A similar functionality exists in NET, but it is packaged differently. The Control class (which acts as a container for your image display) implements the Invalidate and Update methods. It's confusing at first glance, but, the Windows graphics system considers rendering a graphic to a window (or control surface) an expensive operation, so the Invalidate method exists so that windows stores the area to be repainted and then, when it recieves the next WM_PAINT message it actually displays the graphic. This is why when you resize or move a window it displays the refreshed image (a Re-size or move generate a WM_PAINT message.) If you call Update() on your control immediately after your drawing code is executed it should immediately display the refreshed image.
