    <p>Sounds like a fun project! I've implemented databinding on nested content controls within a button before using declarations similar to the following. So in your case the push pin collection would be bound to the items control with each push pin object providing the data for its corresponding button (including the button's nested image and textblock).</p> <p>Let's take a look at a simple example that I hope will guide you in the right direction.</p> <p>To start here's an example of a button template that you could define in the resource dictionary of your choosing. Note the visibility binding on the image and the text binding on the textblock, these properties will be located on a Pushpin_ViewModel we'll define later:</p> <pre><code> &lt;Style x:Name="PushpinButtonStyle" TargetType="Button"&gt; &lt;Setter Property="Template"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate TargetType="Button"&gt; &lt;Grid&gt; &lt;Grid.ColumnDefinitions&gt; &lt;ColumnDefinition Width="*" /&gt; &lt;ColumnDefinition Width="*" /&gt; &lt;/Grid.ColumnDefinitions&gt; &lt;VisualStateManager.VisualStateGroups&gt; &lt;VisualStateGroup x:Name="FocusStates"&gt; &lt;VisualState x:Name="Focused"/&gt; &lt;VisualState x:Name="Unfocused"/&gt; &lt;/VisualStateGroup&gt; &lt;VisualStateGroup x:Name="CommonStates"&gt; &lt;VisualState x:Name="Normal" /&gt; &lt;VisualState x:Name="MouseOver" /&gt; &lt;VisualState x:Name="Pressed"/&gt; &lt;VisualState x:Name="Disabled"/&gt; &lt;/VisualStateGroup&gt; &lt;/VisualStateManager.VisualStateGroups&gt; &lt;Image Grid.Column="0" Grid.Row="0" Grid.RowSpan="2" Height="50" Width="50" Source="Pushpins/pushpinSeaplane.png" Visibility="{Binding PushpinImageVisibility}" /&gt; &lt;Grid Grid.Column="1"&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition Height="39" /&gt; &lt;RowDefinition Height="*" /&gt; &lt;/Grid.RowDefinitions&gt; &lt;Grid Grid.Row="0" Background="Black"&gt; &lt;TextBlock Grid.Row="0" Foreground="White" Text="{Binding PushpinLabelText}" TextWrapping="Wrap" Margin="5" /&gt; &lt;/Grid&gt; &lt;/Grid&gt; &lt;/Grid&gt; &lt;/ControlTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; </code></pre> <p>In your primary view where your pushpins are displayed you may have some sort of items control responsible for displaying your pushpins. Here is an example of such an items control where the data template is a button with two important features 1) the button style we defined above and 2) a click event that will call a toggle method on the corresponding pushpin view model:</p> <pre><code>&lt;ItemsControl ItemsSource="{Binding Pushpins}"&gt; &lt;ItemsControl.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;Button Name="PushpinButton" Click="pushpinButton_Click" DataContext="{Binding}" Style="{StaticResource PushpinButtonStyle}" /&gt; &lt;/DataTemplate&gt; &lt;/ItemsControl.ItemTemplate&gt; &lt;/ItemsControl&gt; private void pushpinButton_Click(object sender, RoutedEventArgs e) { Pushpin_ViewModel pushpin_ViewModel = ((Button)sender).DataContext as Pushpin_ViewModel; pushpin_ViewModel.TogglePushpinVisibility(); } </code></pre> <p>The following view model class would represent the data context of your primary view (the one that contains the items control we defined above). Here we have the collection of pushpins that populate the items control:</p> <pre><code>public class PrimaryPushpinView_ViewModel : INotifyPropertyChanged { public PushpinView_ViewModel() { this.Pushpins.Add(new Pushpin_ViewModel() { PushpinLabelText="First Pushpin" }); } public List&lt;Pushpin_ViewModel&gt; Pushpins { get { return pushpins; } set { if (value != pushpins) { pushpins = value; OnPropertyChanged("Pushpins"); } } } private List&lt;Pushpin_ViewModel&gt; pushpins = new List&lt;Pushpin_ViewModel&gt;(); } </code></pre> <p>And finally here is a representation of the pushpin view model. There would be one instance of this class per pushpin in your pushpin collection:</p> <pre><code>public class Pushpin_ViewModel : INotifyPropertyChanged { public Visibility PushpinVisibility { get { return pushpinVisibility; } set { if (value != pushpinVisibility) { pushpinVisibility= value; OnPropertyChanged("PushpinVisibility"); } } } private Visibility pushpinVisibility; public String PushpinLabelText { get { return pushpinLabelText; } set { if (value != pushpinLabelText) { pushpinLabelText= value; OnPropertyChanged("PushpinLabelText"); } } } private String pushpinLabelText; public void TogglePushpinVisibility() { this.PushpinVisibility = this.PushpinVisibility.Equals(Visibility.Visible) ? Visibility.Collapsed : Visibility.Visible; } } </code></pre> <p>Sorry it took a while to get back to you, crazy day today, hope this helps out.</p>

    1. COForgive my inexperience... Is this to be implemented as a custom control? And in any case, can you give me an example of this being implemented from the code behind? Or would I do it from xaml? I need to be able to control which group(s) of pushpins is displayed, as they are going to be grouped. In the mean time, I will try to figure it out. Thanks!

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.
