I am developing a Add-ins button that do a upstream trace in a network , it works correctly without any error but it does not highlight the traced elements.

I do not know how to highlight the traced elements? thanks in advance

Hi Maria MariaMaldini, I know it's probably outdated. But did you come up with a solution to this issue?

I'm working on something similar to your previous work. And ran into exactly same problem.

Thanks
