Setting zorder

How can I set the zorder of a subgraph so that, when it is expanded, any nodes and links in it will appear over any other existing nodes. I tried setting the opacity of the subgraph to 100% but, that did not accomplish what I wanted.

Thanks.

By “any other existing nodes” do you mean nodes that are not part of that subgraph?

[code] subgraph.Layer.MoveAfter(null, subgraph);[/code]

that is exactly it.

I did not correctly understand the help text for the MoveAfter and MoveBefore functions.

As always, THANK YOU.
