After customizing the Protoapp sample code. The links are not saving in the document. When we open it the link disappears Thats the problem (version is Godiagram 2.5.2 .NET 2.0). Problem is after customizing GraphNode class. im trying to inherit this class from GoGeneralNode. everything is fine. But when I customize it to create ports with no difference between left and right ports then the diagram is unable to save the links. the error is :-
The ProtoApp sample makes use of the GoSimpleNode class, not the GoGeneralNode class. Because GoSimpleNode only has two ports, available as the InPort and the OutPort properties, connecting a link to a GoSimpleNode has no ambiguity regarding which port to use.
