How to disable center connection port

[Jeff]

In my solution, I am setting a node's IsPortEnabled property to false, per your Diagram Builder sample.  A warning is output, stating that IsPortEnabled is obsolete, and that "PortVisibility covers all behaviors."  Two questions arise:

1. Can I assume this means if I set the center port's PortVisibility is AlwaysHidden, that it will not be possible to connect to the center port
2. How can I reliably obtain a reference to the center connection port?

Hi Jeff,

Please find responses to your queries as below.

1.Can I assume this means if I set the center port's PortVisibility is AlwaysHidden, that it will not be possible to connect to the center port	By default, Connection to Centerport is always makes connection between Node and Connector at Node’s Boundary. So, PortVisibility does not affect this default behavior. Please refer to the below screenshot for default behavior. Default Behavior :
2. How can I reliably obtain a reference to the center connection port?	Regarding “obtain a reference to the center connection port”, your requirement has been achieved by using Ports collection property of the Node. We have provided code snippet to represent our solution. Please refer to the below code snippet.   Code Snippet: //getting centerport reference ConnectionPort centerport = n.Ports[0] as ConnectionPort;   Here, n is instance of Node.
