How to get the nodes connected by a given connection

[Giovanni Guarino]

Hello, guys.

When I select an Element (node) in a diagram, I need to make on a different color the elements (nodes) that are connected with the one selected.

I tried in different ways, but I don't find how to "see" the node objects connected to that selected element

Can you please tell me how to do it?

Thanks

Hi Giovanni, 

We have created a sample to change the node color which is connected to other node. When you click on the node, NodeClick event gets triggered. In that event, through event args Node you can get the node on which you clicked. After get the node through node Edges property you get the connector which is connected to the node. By using the connector , we get the node which is connected to connector through FromNode property. Please refer to below code snippet and sample below 

private void EventSink_NodeClick(NodeMouseEventArgs evtArgs) 

        { 

            if(evtArgs.Node.Edges != null) 

            { 

               foreach ( ConnectorBase connector in evtArgs.Node.Edges ) 

                { 

                    (connector.FromNode as FilledPath).FillStyle.Color = Color.Red; 

                } 

            } 

        }

We have attached a video demonstration of how color has been changed.
