    copied!<p>If I read your question correctly and since you didn't mention it yourself you might be looking for the <a href="http://msdn.microsoft.com/en-us/library/system.windows.documents.adornerdecorator.aspx" rel="nofollow noreferrer"><code>AdornerDecorator Class</code></a>, which <em>Provides an adorner layer for elements beneath it in the visual tree</em>.</p> <p>Assuming from its name that <code>ScrollPresenter</code> is derived from <a href="http://msdn.microsoft.com/en-us/library/system.windows.controls.contentpresenter.aspx" rel="nofollow noreferrer"><code>ContentPresenter</code></a>, it's worth noting that for implementing advanced custom controls you might want to surround their <code>ContentPresenter</code> by an <code>AdornerDecorator</code>, just like the <a href="http://msdn.microsoft.com/en-us/library/system.windows.window.aspx" rel="nofollow noreferrer"><code>Window Class</code></a> does, see for example <a href="http://blog.pixelingene.com/2006/11/dont-forget-the-adornerdecorator/" rel="nofollow noreferrer">Don’t forget the AdornerDecorator</a> for a nice real work scenario involving drag&amp;drop too.</p> <p>That is, by means of the <a href="http://msdn.microsoft.com/en-us/library/system.windows.documents.adornerdecorator.aspx" rel="nofollow noreferrer"><code>AdornerDecorator</code></a> you'll ensure the required <a href="http://msdn.microsoft.com/en-us/library/system.windows.documents.adornerlayer.aspx" rel="nofollow noreferrer"><code>AdornerLayer</code></a> to be contained within your custom control, hence removing the need to retrieve it elsewhere by walking up the visual tree, e.g.:</p> <pre><code> &lt;ControlTemplate TargetType="{x:Type CustomWindow}"&gt; &lt;Border ...&gt; &lt;Grid&gt; &lt;AdornerDecorator&gt; &lt;ScrollPresenter ... /&gt; &lt;/AdornerDecorator&gt; &lt;/Grid&gt; &lt;/Border&gt; &lt;/ControlTemplate&gt; </code></pre> <p>Depending on your particular scenario you might need an <code>AdornerDecorator</code> for your custom windows, your custom controls or both.</p> <p>See <a href="http://msdn.microsoft.com/en-us/library/ms743737.aspx" rel="nofollow noreferrer">Adorners Overview</a> for more details on the adorner architecture.</p>
