	How do I highlight a node attached to a link? The nodes attached to the link are ControlNode and CompositeNode. --- Tried and tested method: When the link is selected, set the property (Selected) of the node attached to the link to true. However, the LinkModifying event does not occur and I cannot move the destination or source of the connection.

	Once you select multiple items, you get SelectionMoving event when they are moved, and links' origin / destination cannot change through a multiple-selection. You could draw highlights from DrawForeground event handler instead of selecting attached nodes: Code void OnDrawForeground(object sender, DiagramEventArgs e) { foreach (var link in diagram.Selection.Links) { if (link.SubordinateGroup != null) { foreach (var attached in link.SubordinateGroup.AttachedNodes) { var rect = attached.Bounds; rect.Inflate(2, 2); e.Graphics.DrawRectangle(Pens.Green, rect); //or attached.DrawHandles() } } } } Regards, Slavcho Mindfusion

	I tried it as soon as possible. It works as expected. Regards, Nobu.
