.NET Graphics opbject not redrawing when window comes to foreground.

[notfred]

I have a C#.NET application I'm writing that draws to a Graphics object displayed on screen (in a PictureBox). When I bring the window to the foreground from behind another window, my Graphics object will not redraw (just shows white space anywhere that was obstructed by the overlappnig window). How can I make it redraw the graphics object automatically when the visibility of the window changes?

You need to add a handler to the Paint event.

As it turns out, I was doing exactly what's explained on this page. My graphic draws correctly now.
