Navigate to index in GridView

Hi there,

I have a GridView with a datasource with a potentially infinite library of items. GridView handles this nicely by only loading what is required. My issue is this. If I want to quickly get to all my items that begin with the letter "P", how can I quickly navigate there without scrolling through everything along the way? Fortunately, I can know the exact index of the item, even though it is not yet loaded into the model. I need to somehow navigate to that index.

I have achieved this rather horribly with something along these lines:

Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Low,
                async () =>
                {
                    string letter = "N";
                    object item = null;
                    while (item == null)
                    {
                        item = this.Library.Items.FirstOrDefault(i => (i as Book).Title.StartsWith(letter));
                        this.Library.ScrollIntoView((item ?? this.Library.Items.LastOrDefault()));
                    }
                });

Any ideas would be great.

Thanks,
Dom
