Add new Connection event

[Domenico Mozzone]

Hi there,
I'm evaluating Syncfusion Diagram Windows and I have a question about the best way to get and event when two nodes have been connected by a connector.
I would like an event which argument(s) that specify newly connected nodes.
I tried

this.diagram1.Model.EventSink.ConnectionsChanged += new CollectionExEventHandler(EventSink_ConnectionsChanged);

but it fires twice, for both connected nodes.

thank you
domenico

Hi Domenico,

Please try the following code and let me know whether it solves your problem. The event occurs twice as there are two connection points for a connector.

diagram1.Model.EventSink.ConnectionsChanged += new CollectionExEventHandler(EventSink_ConnectionsChanged);

void EventSink_ConnectionsChanged(CollectionExEventArgs evtArgs)
{
if (evtArgs.ChangeType == CollectionExChangeType.Insert)
{
//NodeCollection nodes = evtArgs.Elements as NodeCollection;
EndPoint conPoint = evtArgs.Element as EndPoint;
ConnectorBase con = conPoint.Container as ConnectorBase;
if (con != null && con.FromNode != null && con.ToNode != null)
{

}
}
}

Regards,
Dinesh
