That is why a NullReferenceException is thrown when you try to use a property or method of the Style object. You should always use the static methods of the NStyle class when applying styles to diagram elements in order to avoid such problems. In your case the code should look like this: NStyle.SetFillStyle(cup, new NColorFillStyle(Color.Empty)); For more information about styles, check out the Styles, Style Composition and Style Sheets documentation topic.
