I think the CollectionView is what you are looking for.

  public ObservableCollection Classes
  {
      get { return _classes; }
  }

  public ICollectionView ClassesCollectionView
  {
      get
      {
          if (_classesCollectionView == null)
          {
              BuildClassesCollectionView();
          }
           return _classesCollectionView;
      }
  }

  private void BuildClassesCollectionView()
  {
      _classesCollectionView = CollectionViewSource.GetDefaultView(Classes);
      _classesCollectionView.Filter = FilterClasses;

      OnPropertyChanged(() => ClassesCollectionView);
  }

  public bool FilterClasses(object o)
  {
      var clas = o as NdfClassViewModel;



      // return true if object should be in list with applied filter, return flase if not
  }

You wanna use the "ClassesCollectionView" as your ItemsSource for your Combobox
