    <p>Don't you just hate it when that happens, not 5 minutes gone since I posted the question, and I've figured out what the problem is - and it <strong>was</strong> something quite basic. On the <code>CollectionViewSource</code> object, there is a <code>View</code> property, which has a <code>Refresh()</code> function. Calling this function after a property on an underlying item contained in the <code>ObservableCollection&lt;T&gt;</code> changes, seems to have done it.</p> <p>Basically, all I had to do was change the <code>CollectionViewSource</code> object into a member variable, and then save it when <code>LoadData()</code> is called:</p> <pre><code>private void MainPage_Loaded(object sender, RoutedEventArgs e) { if (!App.ViewModel.IsDataLoaded) { App.ViewModel.LoadData(); m_isSelectedListView = this.Resources["IsSelectedCollectionView"] as CollectionViewSource; if (m_isSelectedListView != null) { m_isSelectedListView.Source = App.ViewModel.Items; } } } </code></pre> <p>Then, call <code>Refresh()</code> on the view, after any of the items in the underlying <code>ObservableCollection&lt;T&gt;</code> changes. So in MainPage.xaml.cs, just after changing the last item, add the call to refresh:</p> <pre><code>private void ApplicationBarIconButton_Click(object sender, EventArgs e) { ItemViewModel item = App.ViewModel.Items[App.ViewModel.Items.Count - 1]; item.IsSelected = !item.IsSelected; m_isSelectedListView.View.Refresh(); } </code></pre> <p>... and the second Pivot's ListBox is updated instantly. Such a short line of code, a whole world of difference!</p> <p>In the time it took me to write up that question, there are a hundred things I could've done :-( Ah well, better late than never I guess - thought to post the answer here, if only to save someone else tearing out their hair like I did.</p>

    1. COThe `ObservableCollection` automatically implements `INotifyPropertyChanged` where as the `CollectionViewSource` doesn't. This means you have to explicitly tell the `CollectionViewSource` that it needs to update itself. This is what you are doing by calling `Refresh();`.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
