I'm working on an wpf app which contains a listview with quite a lot of data (10 000 to 100 000) rows. The user can apply all sorts of filters to this listview making the filter logic quite advanced (and slow). For now, the relevant part of my code looks like this:

ICollectionView view = CollectionViewSource.GetDefaultView(hugeList.ItemsSource);
view.Filter = new Predicate<object>(FilterCallback);

private bool FilterCallback(object item)
{
  //Filter logic
}

But this runs in the UI thread and blocks the entire application when filtering which gives a very poor user experience. So my question to you all is: does anyone know a 'better' way to filter a listview in wpf or should I filter the underlying ObservableCollection instead?

c# wpf listview filter
