How can I efficiently force a UI refresh of individual rows?

[AlexanderBlackman]

I have some bulk commands that change all selected rows at once.
Right now, the only way I know to force a refresh is to reload the entire ItemsSource, but this isn't efficient.
There must be a better way, but changing UpdateSourceTrigger in a column's datatemplate doesn't work, nor does UpdateLayout

private void HardRefreshItems() //Very wasteful
    {
        _dispatcherQueue.TryEnqueue(() =>
        {
            var items = this.ItemsSource;
            var selected = SelectedItems.Cast<TodoItem>().ToList();
            this.ItemsSource = null;
            this.ItemsSource = items;
            _updatingSelection = true;
            foreach (var item in selected.Where(i => Items.Contains(i)))
            {
                this.SelectedItems.Add(item);
            }
            _updatingSelection = false;
            _messenger.Send(message: new TodoSelectionChangedMessage(selected, fromView: true));

        });
    }

@AlexanderBlackman, I'm afraid I couldn't understand the problem that you are facing, could you give some more information about your implementation?
