	we have a situation where we need to associate one object with another. So we need to know what object is dropped on another. Also is there is a way to group objects on the canvas so we can move it together when dragged on the canvas.

	You could call diagram.getNodesAt(args.getMousePosition()) from NodeModifiedScript or NodeCreatedScript handlers. The nodes are returned in reverse Z order, and the result will probably also contain the node just dropped so ignore it when iterating the list. You can create groups using the DiagramNode.AttachTo() method. I hope that helps, Stoyan

	We are trying Mindfusion NetDiagram library with ASP.Net & VB.Net as the programming language. As per previous reply we need to collect the position of the object using diagram.getNodesAt(args.getMousePosition()) on the client side and update the local variable (hidden variable) and make it available to server side once postback is done. As AttachTo() is a server side method group can only happen once postback is done. So user cant drag the related objects together?

	If you are using JavaApplet mode, there is equivalent DiagramNode.attachTo method defined in the applet. E.g. handle the NodeCreated event and call args.getNode().attachTo(masterNode, 0 /* TopLeft */); I hope that helps, Stoyan
