    copied!<p>What I have now:</p> <pre><code>&lt;Style TargetType="{x:Type ListBox}" x:Key="PhotoListBoxStyle"&gt; &lt;Style.Triggers&gt; &lt;Trigger Property="{Binding Path=IsChecked, ElementName=DetailView}" Value="False"&gt; &lt;Setter TargetName="WrapPanelItem" Property="ItemHeight" Value="100" /&gt; &lt;Setter TargetName="WrapPanelItem" Property="ItemWidth" Value="400" /&gt; &lt;/Trigger&gt; &lt;/Style.Triggers&gt; &lt;Setter Property="Foreground" Value="White" /&gt; &lt;Setter Property="Template"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate TargetType="{x:Type ListBox}" &gt; &lt;WrapPanel Name="WrapPanelItem" Margin="5" IsItemsHost="True" Orientation="Horizontal" ItemHeight="{Binding Value, ElementName=ZoomSlider }" ItemWidth="{Binding Value, ElementName=ZoomSlider }" VerticalAlignment="Top" HorizontalAlignment="Stretch" /&gt; &lt;/ControlTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; </code></pre> <p>The closest I got was to add the Name to the WrapPanel to try and reference from the Trigger above it, but the TargetName cannot be found. I also tried creating a separate style attached to the WrapPanel directly, but that caused issues with controls using the PhotoListBoxStyle that was it's parent:</p> <pre><code>&lt;Style x:Key="WrapPanelSetter" TargetType="{x:Type WrapPanel}"&gt; &lt;Setter Property="ItemHeight" Value="{Binding Value, ElementName=ZoomSlider }" /&gt; &lt;Setter Property="ItemWidth" Value="{Binding Value, ElementName=ZoomSlider }" /&gt; &lt;Setter Property="HorizontalAlignment" Value="Stretch" /&gt; &lt;Setter Property="VerticalAlignment" Value="Top" /&gt; &lt;Setter Property="Orientation" Value="Horizontal" /&gt; &lt;Setter Property="Margin" Value="5" /&gt; &lt;Style.Triggers&gt; &lt;DataTrigger Binding="{Binding Path=IsChecked, ElementName=DetailView}" Value="False"&gt; &lt;Setter Property="ItemHeight" Value="100" /&gt; &lt;Setter Property="ItemWidth" Value="400" /&gt; &lt;/DataTrigger&gt; &lt;/Style.Triggers&gt; &lt;/Style&gt; </code></pre> <p>Thanks for any help. I am more than willing to try a different approach if there is a better option!</p>
