I created a group manually, but when I delete the group, the ports are still shown on my screen. Is there a way to prevent that from happening? I want when I delete the group for the ports to be deleted as well. What I did, I have a shape with couple of ports, then I group multiple of that shapes. However when I delete the group, the ports are not deleted with the group.

Below I edited the second button, sorry for the typo

private void barButtonItem2_ItemClick(object sender, ItemClickEventArgs e)

{

NFlowChartingShapesFactory factory = new NFlowChartingShapesFactory(nDrawingDocument1);

NShape entityShape = factory.CreateShape(FlowChartingShapes.Process);

entityShape.Bounds = new NRectangleF(100, 100, 200, 100);

entityShape.Text = "my text";

nDrawingDocument1.ActiveLayer.AddChild(entityShape);

}
