Thank you for sharing your scenario with us. Unfortunately at the moment the RadDiagram
doesn't support it but based on your feedback, we decided to log your suggestion as a feature request in our PITS
. Basically what we will try to implement is expose an event that will be fired before a connector gets activated so that you can manipulate its state and stop the activation if needed.
Do you think such an event will allow you to implement your scenario?
