	Hi, I need to restrict the nodes moving out of the diagram canvas while dragging, re-sizing, child adding etc. In-fact i don't want any shapes to go out of canvas at any user actions. Thanks Kiran B

	Hi, You could prevent it from nodeModifying and nodeCreating events like this: Code function onNodeModifying(sender, args) { if (!sender.getBounds().contains(args.getNode().getBounds())) args.setCancel(true); } Alternatively, align the node to nearest diagram border if you detect it's not entirely inside diagram.Bounds from nodeCreated/nodeModified handlers. I hope that helps, Stoyan
