Using Scrollbars with User Painted Controls

[Alex Glass]

Im using double buffering to draw a scheduling grid on a form. The grid can
take up more space than the form can display. I would like to use a
scrollbar to control which part of the window the user can view. Does
anyone know a simple way to do this?

Any help is always greatly appreciated,

Take a look at the control's 'AutoScroll' property (inherited from
'ScrollableControl').

The problem with the autoscroll property is that the origin (X,Y start of
drawing) remains the same while using the scrollbar. This means that if i
scroll down to the bottom of the page, the window still only paints the
upper portion. Furthermore I was unable to find the event that reacts to
the scrollbar moving.

Try:

g.TranslateTransform(this.AutoScrollPosition.X, this.AutoScrollPosition.Y);

before painting
