Avoid snaptonode to the same origin / target (Read 3638 times)

	Hello, On a flowchart, I would like to activate the snaptonode property when the user tries to create a link between two nodes, however if the snaptonode is true, and the origin node is big enough, the link tries to "snap" to the origin node and it is very awkward. Is there any way to avoid the "snaptonode" when the link being drawed is over the same node that initiates it? Thank you in advance Regards Gabriel Pulido

	Hi, The origin node is ignored for the snap-from-distance feature, but not when the link end is inside it. You could work around it like that: Code diagram.LinkCreating += (s, e) => { e.Link.AutoSnapToNode = e.Origin != e.Destination; }; I hope that helps, Stoyan

	Hello, Thank you for your quick answer. The solution partially solved the problem, however if the user start draggin from one node and drag over a second node, then the snaptonode is changed to "true", but if he doesn't release and goes back to the original node, as the flag has been changed to "true" and the linkcreation is not launched again unless I set the AllowSelfLoops to true. Is there any way to avoid setting the AllowSelfLoops to true to achieve the functionality desired?

	Hi, You could prevent self-loops from LinkCreating too: Code diagram.AllowSelfLoops = true; diagram.LinkCreating += (s, e) => { e.Link.AutoSnapToNode = e.Origin != e.Destination; e.Cancel = e.Origin == e.Destination; }; I hope that helps, Stoyan
