Hi there,

I am trying to write an UI, where when the user drags the node into the “designated area”, a specific port of the node will be “disabled” and “enabled” when the node is outside the “designated area”. I have been following the Northwood.Go sample BoxArea. However, I am encountering some issue, where when I drag the node out from the “area”, the node is still of in childlist of the GoSubGraph.

Any forms of advice will be appreciated.


Look at what NodeLinkDemo does in GraphView.OnBackgroundSelectionDropped
