You need to set GoView.DocPosition so that the origin is where you want it. Caution: we do not support changing the coordinates so that increasing values of Y go “up” – they always go “down”, just as increasing values of X always go “right”.
By default the GoView only allows scrolling to where the GoDocument exists. Unless you have already added objects at negative Y coordinates in the view’s document, you’ll need to first set the document’s bounds. Then you can set the GoView.DocPosition. Something like:
SizeF sz = goView1.DocExtentSize;
PointF pos = new PointF(0, -sz.Height);
goView1.Document.Bounds = new RectangleF(pos, sz);
goView1.DocPosition = pos;
