    <p>Probably a simple one but i can't seem to get it to work, here's the XAML for the listview and bindings;</p> <pre><code>&lt;ListView VerticalAlignment="Stretch" HorizontalAlignment="Stretch" x:Name="lstTrackers" ItemsSource="{Binding Path=MainWindowViewModel.TrackerCollection}" HorizontalContentAlignment="Stretch"&gt; &lt;ListView.ItemContainerStyle&gt; &lt;Style TargetType="{x:Type ListViewItem}"&gt; &lt;Style.Triggers&gt; &lt;DataTrigger Binding="{Binding Path=LastTransmitted}" Value="True"&gt; &lt;Setter Property="Background" Value="Green"/&gt; &lt;/DataTrigger&gt; &lt;DataTrigger Binding="{Binding Path=LastTransmitted}" Value="False"&gt; &lt;Setter Property="Background" Value="White"/&gt; &lt;/DataTrigger&gt; &lt;/Style.Triggers&gt; &lt;/Style&gt; &lt;/ListView.ItemContainerStyle&gt; &lt;ListView.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;TextBlock Text="{Binding Path=Description}" x:Name="listTextClick" MouseLeftButtonUp="listTextClick_MouseLeftButtonUp" HorizontalAlignment="Stretch"/&gt; &lt;/DataTemplate&gt; &lt;/ListView.ItemTemplate&gt; &lt;/ListView&gt; </code></pre> <p>and the property that i'm trying to bind it to;</p> <pre><code> public class TrackerViewModel : ViewModelBase { readonly Tracker _tracker; public TrackerViewModel(Tracker tracker) { _tracker = tracker; } public bool LastTransmitted { get { return _tracker.lastTransmitted; } set { _tracker.lastTransmitted = value; OnPropertyChanged("LastTransmitted"); } } } </code></pre> <p>And then i'm simply trying to set the boolean to true, which i assumed would trigger the style to proc;</p> <pre><code> _trackerViewModel.LastTransmitted = true; </code></pre> <p>However, nothing at all seems to happen. Is there something simple yet imperative that i'm missing?</p> <p>Note: I've already tried changing "true" to "True", just incase.</p> <p>Edit 1: It seems that the change isn't being notified, which is very strange because i'm certain it was. If i change the trigger to;</p> <pre><code>&lt;Style x:Key="listBoxStyle" TargetType="{x:Type TextBlock}"&gt; &lt;Style.Triggers&gt; &lt;DataTrigger Binding="{Binding Path=LastTransmitted}" Value="True"&gt; &lt;Setter Property="Background" Value="Green"/&gt; &lt;/DataTrigger&gt; &lt;DataTrigger Binding="{Binding Path=LastTransmitted}" Value="False"&gt; &lt;Setter Property="Background" Value="Blue" &gt;&lt;/Setter&gt; &lt;/DataTrigger&gt; &lt;/Style.Triggers&gt; &lt;!--&lt;Setter Property="Background" Value="Red"/&gt;--&gt; &lt;/Style&gt; </code></pre> <p>Then the textblocks are all blue, as denoted by the boolean being set to true. However When it is set to true, and the property is notified, nothing changes. Perhaps the list isn't refreshing properly? I'm sure it's linked to a ObservableCollection.</p> <p>EDIT 2: and on that note, it turns out i'm using a custom list; "ThreadedBindingList". It might not be updating from the OnNotify..so i'll have to try working around this.</p>

Guidance
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.
