	Hello guys, I have this problem while using these code to manually create a relationship between 2 entities. The code is: Code var link = new DiagramLink(diagram); link.Origin = e1; link.Destination = e2; link.OriginAnchor = 0; link.DestinationAnchor = 1; diagram.Links.Add(link); The Destination point of the relationship is correct but the Original point is always stuck at the top left of Window form, as in this photo Please help.

	Hi, The link.*Anchor properties will do nothing if you haven't set nodes' AnchorPattern. If you need to specify which rows should get connected, set the OriginIndex and DesintationIndex properties instead, or pass them as arguments to CreateDiagramLink method: Code var link = new DiagramLink(diagram); link.Origin = e1; link.Destination = e2; link.OriginIndex = 0; link.DestinationIndex = 0; diagram.Links.Add(link); //diagram.Factory.CreateDiagramLink(e1, 0, e2, 0); I hope that helps, Stoyan

	If you need to arrange the tables automatically, try setting NodeDistance / LayerDistance properties in some of the layout classes: Code var layout = new LayeredLayout(); layout.Orientation = MindFusion.Diagramming.Layout.Orientation.Horizontal; layout.LayerDistance = 40; layout.Arrange(diagram); I hope that helps, Stoyan

	Thank you for your reply, could you also tell me how to change color for the diagramLink arrows? Also is there anyway to disable delete control via keyboard delete button for the diagramLink?

	You can change link's colors by setting its Pen, HeadPen and Brush properties. Set DiagramView.DelKeyAction = None to disable deleting items altogether, or handle LinkDeleting validation event to prevent deleting links only. I hope that helps, Stoyan

	Now I have another problem, the this.diagram.Print() won't work, it said does not contain a definition for 'Print'. Am I missing something?

	Call DiagramView.Print() instead of Diagram.Print(). I hope that helps, Stoyan

	It's a little blurring but least it worked, if you have any advice to improve the quality please tell me. Thank you for your support so far

	What's blurry exactly - graphics on printed page? If printing in gray-scale you will get some patterns printed instead of colors and gradients, which will make text harder to read, so you could try disabling brushes to get only text and frame lines: Code diagramView.PrintOptions.EnableInterior = false; diagramView.PrintOptions.EnableShadows = false; You might also try changing anti-aliasing options temporarily before printing: Code diagramView.SmoothingMode = SmoothingMode.None; diagramView.TextRenderingHint = TextRenderingHint....; I hope that helps, Stoyan
