First, never store a Graphics object and always call Dipose on it when you're finished.

Second, using the ClientRectangle of the Button means that the rectangle will be within the Button, which maintains its own state. Drawing a rectangle within said bounds won't be visible. Instead you must inflate the rectangle (you can use Rectangle.Inflate) by the size of the pen (5, in your example).

You'll also want to do this in the override for OnPaint in your Panel-derived class (or in the Paint event if from another - possibly container - class. Painting this rectangle once will work (if you take into account what I mentioned above) but once the surface requires repainting it won't show up (and only part of it - the invalidated part - will disappear if the whole surface doesn't need repainting). So, in DrawScanArea(Button button) instead set a value to signify that the border should be painted (like a non empty rectangle which you would have to store anyway) and in OnPaint check that state and draw the border if necessary.
