How to establish the connection when a node is dropped on a connector
1 min read
We have a support to connect with the Node which is dropped on a Connector. This can be achieved by using ItemDropEvent for the Diagram. This Event will get invoke with Source and Target (Collection of Intersected Elements) of Intersection. We have provided code example for this.
Please refer to the code example as below.
C#
//ItemDropEvent for Diagram
IGraphInfo sfdiagram = (diagram.Info as IGraphInfo);
sfdiagram.ItemDropEvent += Diagram_ItemDropEvent;
//ItemDrop Event
private void Diagram_ItemDropped(object sender, ItemDropEventArgs args)
{
if(args.Source is Node && args.Target!=null)
{
foreach(var con in args.Target as List<object>)
{
if(con is IConnector)
{
(con as IConnector).SourceNode = args.Source;
}
}
}
}
Here,
diagram – refer to the instance of Diagram.
