WP8 LongListSelector SelectedItem not bindable

Question

In WP8, they forgot to provide SelectedItem as a dependency property, hence I\'m not able to bind to it. I fixed that using this: http://dotnet-redzone.blogspot.com/2012/11/wind

It appears that the custom LongListSelector class that you are using does not handle the setter properly.

Replace the OnSelectedItemChanged callback with the following:

    private static void OnSelectedItemChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var selector = (LongListSelector)d;
        selector.SetSelectedItem(e);
    }

    private void SetSelectedItem(DependencyPropertyChangedEventArgs e)
    {
        base.SelectedItem = e.NewValue;
    }
