    copied!<p>I think that in your case the best way to achieve this is to get the scroll viewer inside the tree view completely out of the way by creating a bare-bones tree view style like this:</p> <pre><code> &lt;Style x:Key="TreeViewStyle1" TargetType="sdk:TreeView"&gt; &lt;Setter Property="Template"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate TargetType="sdk:TreeView"&gt; &lt;Grid&gt; &lt;ItemsPresenter Margin="5,5,19,19" d:LayoutOverrides="Width, Height"/&gt; &lt;/Grid&gt; &lt;/ControlTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; </code></pre> <p>Then simply apply the template to your scroll viewer and wrap it up with an external scroll viewer, this way:</p> <pre><code>&lt;Grid x:Name="LayoutRoot" DataContext="{Binding Source={StaticResource TreeViewSampleData}}"&gt; &lt;ScrollViewer&gt; &lt;sdk:TreeView ItemsSource="{Binding RootCollection}" ItemTemplate="{StaticResource FirstLevelTemplate}" Style="{StaticResource TreeViewStyle1}"/&gt; &lt;/ScrollViewer&gt; &lt;/Grid&gt; </code></pre> <p>Now the tree view has no way to communicate with the scroll viewer and therefore it won't be able to scroll when an item is selected.</p> <p>Keep in mind that this eliminates any automatic scrolling and only manual scrolling is now possible. You can still add your own automatic scrolling by using behaviors or TargetedTriggerAction(s).</p> <p>Make sure not to set any sizes on the tree view, so that it grows freely inside the scroll viewer.</p> <p>I hope this helps.</p>
