	Do you mean you have arranged your nodes in columns, and the nodes from the first column should not scroll?

	Thanks , this is the code private void diagram_NodeModifying(object sender, NodeValidationEventArgs e) { try { ShapeNode task = (ShapeNode)e.Node; Point p=e.MousePosition; if (p.Y != ((DiagramNode)(task)).Bounds.Y) { e.CancelDrag(); } } catch { } }

	This code will make it very hard for the user to move a node. Set node.Cosntraints.MoveDirection = DirectionConstraint.Horizontal to allow only horizontal node movement. I hope that helps, Stoyan
