问题 Another question related to this one. I have a List<SortableObjects> that is the DataContext of my MainWindow. I use that list to populate a ListBox and a ComboBox . When I sort the items, both the ComboBox and the ListView get updated all right. But now I need the ComboBox to be sorted in a different way than the ListView . I. E.
