I'm using the MVVM design pattern, with a ListView bound to a ListCollectionView on the ViewModel. I also have several comboboxes that are used to filter the ListView. When the user selects an item from the combobox, the ListView is filtered for the selected item. Whenever I want to filter on top of what is already filtered, it undoes my previous filter like it never happened. The same is also true for removing a filter. Removing a filter for one combobox removes all filters and displays the original list. Is it possible to have multiple, separate filters on the same ListCollectionView?
