	Set the transparent node's Locked property.

	If you don't want to lock the transparent node, that's actually a good application of behavior classes we discussed earlier. The following StartDraw overload will let you move an opaque node behind a transparent one, or move the transparent node if it's the only one at that location. Code public override InteractionState StartDraw(PointF point) { var nodes = DiagramView.Diagram.GetNodesAt(point); foreach (var node in nodes) { var shapeNode = node as ShapeNode; if (shapeNode != null && shapeNode.Transparent) continue; var handle = node.HitTestHandle(point); if (handle != null) return new InteractionState(node, handle, Action.Modify); } return base.StartDraw(point); } I hope that helps, Stoyan

	Thanks, it can work. But when I set Transparent property to true, whole shape is transparent include border. I want border is visible what is the easy way to do it?

	Set shape.Brush = new SolidBrush(Color.Transparent); You'd probably want to set the same value for ShadowBrush, if you haven't disabled shadows altogether. Then check the Brush.Color value instead of Transparent property when hit-testing in code above.
