    <p>You need to raise the <code>PropertyChangedEvent</code> for the property <code>LastTransmitted</code>, so that the UI gets notified that the property has changed and your Triggers are executed.</p> <p>Since you inherit your class from <code>ViewModelBase</code> I assume that the class implements <code>INotifyPropertyChanged</code> and provides a method to raise the event.</p> <pre><code>public bool LastTransmitted { get { return _tracker.lastTransmitted; } set { _tracker.lastTransmitted = value; RaisePropertyChanged("LastTransmitted"); } } </code></pre> <p><strong>UPDATE:</strong></p> <p>When i understand you right, you want that the Background of the <code>TextBlock</code> gets changed when the <code>LastTransmitted</code> property changes. TextBlock by itself has no Background-Property, so you have to put the TextBlock into an container like <code>Grid</code> or <code>StackPanel</code>.</p> <p>Here´s a DataTemplate for your ListBox that does what you want.</p> <pre><code>&lt;DataTemplate&gt; &lt;StackPanel&gt; &lt;StackPanel.Style&gt; &lt;Style TargetType="StackPanel"&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;/StackPanel.Style&gt; &lt;TextBlock HorizontalAlignment="Stretch" Text="{Binding Path=Description}" /&gt; &lt;/StackPanel&gt; &lt;/DataTemplate&gt; </code></pre>

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.

SQuiL has stopped working due to an internal error.

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