#### Links Into

These are all the Links that lead into your selected Node. In code, this highlighting is performed by:

      Node node = myDiagram.SelectedPart as Node;
      if (node != null) {
        foreach (Link link in node.LinksInto)        // For that Node, get LinksInto, cast all as
          ((NavModelLinkData)(link.Data)).Highlight = 1;  // NavModelLinkData, and set Highlight to true
      }

All the Links leading into the SelectedNode are obtained by the LinksInto property. Then we get each Link's data and set its Highlight property to 1, as any Link is 1 "relationship" or "step" from the Node it connects with.
