	Hi everybody, is there a way to prevent a user to select nodes and links? Behavior.DoNothing doesn't suit to me, as I am using a layer on top of the component which manages diagram "logical" elements to edit/remove them, so I need them not to be selected. Thank you!

	Oh, sorry, I've just found this one: Stoyo wrote on Jun 5^th, 2013 at 11:12am: Hi, We haven't implemented EnabeldHandles yet in the JavaScript library. At this time you can prevent both modification and selection by setting the Locked property. If you want to let users select items but not modify them, call args.cancelDrag() from the nodeModifying event handler. In that case you can hide the handles by overriding the nodes' addHandlesToCanvas method: Code var originalAddHandles = ShapeNode.prototype.addHandlesToCanvas; ShapeNode.prototype.addHandlesToCanvas = function (point) { originalAddHandles.apply(this, []); Array.forEach(this.handles, function (handle) { handle.brush = "transparent"; handle.pen = "transparent"; }); }; I hope that helps, Stoyan I'm going to try it. Sorry again.

	Hi, In WpfDiagram you can also prevent selection from the NodeSelecting validation event handler by setting e.Cancel. I hope that helps, Stoyan
