Hi,

You can iterate over the diagram.Selection.Nodes collection and check the ZIndex value of the nodes.

I hope that helps,
Stoyan

Has this node been added to the diagram when you try to set ZIndex? It won't work before that, because the ZIndex setter needs to change the node's position within diagram.Items.

Try these settings:

Style = LinkStyle.Polyline;
SegmentCount = 1;
IntermediateShape = Arrowheads.Circle;
// and perhaps HeadShape = null

I hope that helps,
