The attached, simple script for a form has a
ComboBoxon the top-right (The list). I want to change its background color. But nothing changes when I add this line to its control definition:
cb.BackgroundColor = Colors.GreenWhat is the proper way to do this or, despite being listed in the documentation for Eto Forms, does this not work for a ComboBox? Note that changing the background color of other controls on this form does work (see background behind the word: something).
