    <p>I am working with the Nokia Maps control in Windows Phone 8. Here is the code I have at present (relevant parts only)</p> <p>C#</p> <pre><code>public ObservableCollection&lt;LocationViewModel&gt; ItemLocations { get { return new ObservableCollection&lt;LocationViewModel&gt;() { new LocationViewModel() { Display = "MVVM Test", Location = new GeoCoordinate(43.07441, -88.25609) } }; } } </code></pre> <p>XAML:</p> <pre><code>&lt;maps:Map Center="{Binding MapCenter, Mode=TwoWay}" ZoomLevel="{Binding ZoomLevel}"&gt; &lt;maptk:MapExtensions.Children&gt; &lt;maptk:MapItemsControl ItemsSource="{Binding Path=ItemLocations}"&gt; &lt;maptk:MapItemsControl.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;maptk:Pushpin GeoCoordinate="{Binding Location}" Content="{Binding Display}" /&gt; &lt;/DataTemplate&gt; &lt;/maptk:MapItemsControl.ItemTemplate&gt; &lt;/maptk:MapItemsControl&gt; &lt;/maptk:MapExtensions.Children&gt; &lt;/maps:Map&gt; </code></pre> <p>Right now, when the Map page loads, it centers on the correct location, however, no matter what I do with the ItemLocations list I get no points displayed on the Map. I went ahead and statically defined maptk:MapItemsControl.Items with some static points and it worked fine, it is only when I attempt binding (shown above) that it fails.</p> <p>The solution is utilizing Caliburn Micro for MVVM. As you can see with the sample above, I have hard coded the locations list in the ViewModel but <em>get</em> is never called, which is mysterious to me. If I only define PushPins as children to MapExtensions.Children it works.</p> <p>I am starting to wonder if ItemsSource is not bindable, but I feel that would be ridiculous. Help please</p> <p>Thanks in advance</p>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
