Dear Sir/Madam,

We create a link using diagram.Factory.CreateDiagramLink(OriginPoint, EndPoint), then add some properties:

Link.Origin = [DiagramNode];
[DiagramNode].OutgoingLinks.Add(Link);
Link.Tag = true;
Link.AutoRoute = true;
Link.CascadeOrientation = MindFusion.Diagramming.Silverlight.Orientation.Horizontal;

The origin node ([DiagramNode] in the example above) has its anchor pattern set to :

event1.AnchorPattern = MindFusion.Diagramming.Silverlight.AnchorPattern.LeftInRightOut;

However, I can still pick up the link I just created and move the link so that its origin is any other node on the diagram. I can also move the link so that its anchor point changes from the right-hand side to the left-hand side of the node, despite the fact that the node's anchor pattern would appear not to allow this.

While I want to allow our users to move the end point of the link to any node on the diagram, I want to "lock" the origin so that the user can neither move the link to a different origin node nor move the link so that its origin anchor point is on the left hand side of the node.

All help, thoughts, etc. appreciated.

Thanks,

Mark
