Maximum number of diagram connections

[Rostislav]

Hello, 
i was wondering, if there is a simple way to set a maximum number of possible connections for diagram shape connector?
Moreover Is there a way to check actual connections for particular connector?
If there was i guess i could then check those and i could try not to allow user to create additional connection.
Thank you!

Hello Rostislav,

 There is no built-in way to restrict the number of connections per Connector, but you can easily achieve this. 
You should handle the ConnectionManipulationStarted/Completed event and in the event arguments, you can check something like the following and mark the event as handled - this will prevent the user from creating the connection:

if (diagram.GetOutgoingConnectionsForShape(e.Shape).Count(c => c.SourceConnectorResult == e.Connector) > 2)
            {
                e.Handled = true;
            }

Please let us know if this is working for you.
