    <p>Well, it looks like you are trying to use a "normal" DependencyProperty on the parent UserControl, and an "attached" DependencyProperty on the child UserControl. You need to pick one way. :)</p> <p>EDIT for clarification: There are two ways of registering a dependency property, "Normal", like so:</p> <pre><code>public static readonly DependencyProperty BobProperty = DependencyProperty.Register("Bob",....) </code></pre> <p>and Attached:</p> <pre><code>public static readonly DependencyProperty BobAttachedProperty = DependencyProperty.RegisterAttached("BobAttached",...) </code></pre> <p>Let's say the control you are registering these properties on is called "MyPanel". To use each property:</p> <pre><code>&lt;MyPanel Bob="somevalue" MyPanel.BobAttached="somevalue"/&gt; </code></pre> <p>Note the need to specify "where the attached property is defined". Attached properties are great when you have some bit of behavior or functionality that applies to multiple types of controls.</p> <p>That said, perhaps there is a better way to do this - If the parent UserControl contained an ItemsControl, the ItemTemplate for that control could be a DataTemplate that contained the ItemDetailsView, in which case you could use standard data binding to do what you needed to:</p> <pre><code>&lt;UserControl blahblahblah&gt; &lt;ItemsControl ItemsSource="{Binding WhereYourItemsAre}"&gt; &lt;ItemsControl.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;ns:WhatYourChildViewIsCalled DataContext="{Binding}"/&gt; &lt;/DataTemplate&gt; &lt;/ItemsControl.ItemTemplate&gt; &lt;/ItemsControl&gt; &lt;/UserControl&gt; </code></pre>

    1. COThanks for the suggestion! Could you explain your first statement a bit more? I've edited the question to include my declaration for the dependancy proeprty.

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.
