	Hi, If you need to show that image in the part of the diagram that's visible in the view regardless of scroll position, it is best to do that from the DrawBackground event handler: Code private Image backImage = Bitmap.FromFile(@"..."); private void diagram_DrawBackground(object sender, DiagramEventArgs e) { RectangleF viewport = diagramView.ClientToDoc(diagramView.ClientRectangle); Utilities.DrawImage(e.Graphics, backImage, viewport, ImageAlign.Fit); } If for some reason you must use a node, handle the ScrollChanged and ZoomChanged events and set the node's Bounds to the viewport rectangle as calculated above. I hope that helps, Stoyan
