I have a flowchart on a form.  Its the only control on a form, and its set to Dock.Fill.

The form is then loaded into an MDI.

I seem to be locked into a certain size canvas for the control.  I want to have the drawing surface of the control be very large, giving users a large work area, and have the scroll bars(and an overview control in another window) to navigate around the space.

If I remove the chart from Dock.Fill, and manually set the size of the control, the scrollbars disappear.

Any ideas on how to do this or perhaps an "auto expanding" feature that grows the canvas as items are dropped at the edges?
