In the LinkCreated and LinkModified handlers check the OriginAnchor or DestinationAnchor properties, depending on which AdjustmentHandle has been used. The *Anchor properties return the indices of the anchor points to which the link is connected.

I hope that helps,
Stoyan

Hi,

I have a question related to this.

How do I set the color back when all links have been deleted from an anchor point? I can use LinkDeleted, but I don't know if there are other links that are still attached to OriginAnchor and/or DestinationAnchor...

Thanks,
Marie

Hi,

You'll have to iterate over all links attached to the node and check if any of them still has this point as Origin/DestinationAnchor.
