	I seem to be failing to find a solution for this simple task. I want to draw a box (Shape) then i want to draw an arrow (link) then starts from outside the box but ends up in the box. The problem is the link tries to automatically anchor to the box. sounds simple but i have struggled many a moon to try and resolve this one. i have tried turning off allowincomming and out going links but you get a no entry sign when you draw into the box. Ive also tried setting anchor patterns to nothing so it wont latch onto the box. I can get this to work with a link that is not a polyline, but i want a single straight line. Any help would be great.

	You could move the last control point to the current mouse pointer location: Code private void diagram_LinkCreated(object sender, LinkEventArgs e) { DiagramLink link = e.Link; link.ControlPoints[link.ControlPoints.Count - 1] = diagramView.ClientToDoc(diagramView.PointToClient(MousePosition)); link.UpdateFromPoints(); } I hope that helps, Stoyan

	Thanks for this. I managed to stumble across a solution by accident in the end, all you have to do is make all nodes / boxes locked before adding the links, works perfectly. Thanks for your suggestion though.

	Locked nodes + AllowUnconnectedLinks will create the link exactly at the end point, but will not associate links with nodes (link.Destination will remain null). I suppose that will work for you if using the control only as a drawing tool and don't need to traverse the graph later.
