Hi,

You can use the box.AnchorPattern.PatternId property to get a string id of the anchor pattern and store it in the DB. Then each link has an OrgnIndex and DestIndex property that specifies to each point of the origin and destination nodes' anchor patterns the arrow's ends are docked. So you must save these indices for each arrow and later use the CreateAnchoredArrow method to restore the link from the database info.

I hope this helps.

Ok if you don't want to store the arrows points you could go like this:

- store the relations between nodes in a helper many-to-many table
- create arrows between related nodes as read from the relations table by calling CreateArrow
- at the end, use either some of the automatic layout routines to arrange the whole diagram or set all arrows Dynamic and call the RouteAllArrows method
