	How do I prevent a user from linking a node to its self? I have tried handling Diagram.LinkCreating with following code: ' cancel if linking to self If e.Link.Origin Is e.Link.Destination Then e.Cancel = True End If This doesnt seem to work though.

	To prevent that for all nodes in the diagram, set Diagram.AllowSelfLoops = false. To do that for a specific node using an event handler, compare LinkValidationEventArgs.Origin with LinkValidationEventArgs.Destination, instead of DiagramLink.Origin with DiagramLink.Destination. I hope that helps, Stoyan
