    <p>I'm trying to create a simple style data trigger that pulls it's binding value from a viewmodel property, as you can see below:</p> <pre><code> &lt;StackPanel Name="stackTextPanel" Orientation="Horizontal" Margin="0,8,0,0"&gt; &lt;StackPanel.Style&gt; &lt;Style TargetType="{x:Type StackPanel}"&gt; &lt;Style.Triggers&gt; &lt;DataTrigger Binding="{Binding QuickDrawBarPinned}" Value="False"&gt; &lt;Setter Property="Margin" Value="0,8,0,0" /&gt; &lt;/DataTrigger&gt; &lt;DataTrigger Binding="{Binding QuickDrawBarPinned}" Value="True"&gt; &lt;Setter Property="Margin" Value="0,48,0,0" /&gt; &lt;/DataTrigger&gt; &lt;/Style.Triggers&gt; &lt;/Style&gt; &lt;/StackPanel.Style&gt; </code></pre> <p>I have also tried the variant</p> <pre><code>Binding="{Binding Path=QuickDrawBarPinned}" </code></pre> <p>but this is still not working when I press the button that changes the <strong>QuickDrawBarPinned</strong> property what am I doing wrong?</p> <p>I've implemented the property as so:</p> <pre><code> private bool _quickDrawBarPinned = false; /// &lt;summary&gt; /// Indicates if the Quick Draw Bar is pinned (stuck) or unpinned (retractable) /// &lt;/summary&gt; public bool QuickDrawBarPinned { get { return _quickDrawBarPinned; } set { _quickDrawBarPinned = value; OnPropertyChanged("QuickDrawBarPinned"); } } </code></pre> <p>This is the method that implements the change control</p> <pre><code> public virtual void OnPropertyChanged(string propertyInfo) { App.Current.Dispatcher.BeginInvoke((Action)(() =&gt; { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(propertyInfo)); } } )); } </code></pre>

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.
