ShapeControlPoints are not displayed when they are added to an already displayed ShapeNode (Read 3297 times)

	Hi, I want to add ShapeControlPoints to a ShapeNode that is already displayed, but they only appear after the Node is stretched or completely new added to the diagram. I already tried to Repaint (shapeNode.Repaint(true)) and Invalidate the Node, but that didn't help either. Is there another function that forces the Diagram to display the ShapeControlPoints when they are added? Best regards, Cyrinael

	Hi, Assigning the shape back to the node seems to work - Code private void OnNodeClicked(object sender, NodeEventArgs e) { var node = e.Node as ShapeNode; if (node != null) { var shape = node.Shape; shape.ControlPoints.Add( new ShapeControlPoint("p5", 50, 0, 100, UnitType.Percentage, 20, 0, 100, UnitType.Percentage) { MaxXRelativeToWidth = true }); node.Shape = shape; } } Regards, Slavcho Mindfusion

	Hi Slavcho, The control points are now correctly added, but now I have the problem, that with the re-assignment all changes I have done to any other ShapeControlPoint are reverted. Best regards, Cyrinael

	Hi, Build from last post (https://mindfusion.eu/_beta/wpfdiag341.zip) also adds a ShapeNode.UpdateShapeControlPoints() method, call it instead of reassigning the Shape property. Regards, Slavcho Mindfusion
