Hi ,

I am facing an other problem , is there any way to determine if a port is already connect or not ? because I am trying to district the connection from output ports  so that every one can be used just once as Head port

best regards

Hi Abdallah,

We don’t have property to check whether port is connected. But we have to write own logic to check status of port. We have created a sample in which, we created CustomPort having property named “IsConnected”. The IsConnected property is being updated in ConnectorDragEnd event. Connector drag end event will be fired whenever the connector ends are dragged. By checking the IsConnected property we can allow connector to connect that port. Hence we can restrict the connection port to be connected to single line at a time.  For more information kindly refer the attached sample.

You can also refer our dash board sample InPortOutPort Demo,
