Please check my answer before - I linked objects in ExtendedDictionary and allpy new position to all lined objects during move events.
Don't forget to handle copy/paste/delete for your objects it you want to store linked object list for copies objects for example.
Editor is easy - I have 2 promt dialogs - choose first object/point and choose linked object. And then I store this new link - I add new key/value in ExtendedDictionary as handle=linked_handle1, linked_handle2,... So I can easy parse it during any event.
Thanks for your fast reply.
I will try to do as you suggest.
But, also I want to create a network topology in which users will search for shortest or longest path between the nodes.
Do you have any suggestion for this?
Your task can be separated to 2 items: find path and show it.
If about second you can do it with OverruledDraw. Add special flag to ExtendedDictionary and it this flag is 1 - draw special line else standard. It allows you to draw path.
Second item has many ways. For example you can use additional library (for example C# libraries as GraphSharp or anythink else) or you can use graph theory for it.
