Preventing a line from connecting to another shape?

[Ron Alan Sawyer]

Is there any way to prevent a line from connecting to other shapes? Is there a property that I can set that will prevent a line from connecting?

Thanks
Ron

Hi Ron,

You can use the following event to prevent the line connector from connecting to a shape.

diagram1.Model.EventSink.ConnectionsChanging += new CollectionExEventHandler(EventSink_ConnectionsChanging);

void EventSink_ConnectionsChanging(CollectionExEventArgs evtArgs)
{
evtArgs.Cancel = true;
}

This example prevents any connection creating. How is it possible to allow the connection between to nodes, but after that, this exact connection could not be moved to another node or made disconnected from of of its nodes.
