    <p>The binding problem comes from the default style for ListBoxItem. By default when applying styles to elements WPF looks for the default styles and applies each property that is not specifically set in the custom style from the default style. Refer to <a href="http://www.interact-sw.co.uk/iangblog/2007/02/14/wpfdefaulttemplate" rel="nofollow noreferrer">this great blog post</a> By Ian Griffiths for more details on this behavior.</p> <p>Back to our problem. Here is the default style for ListBoxItem:</p> <pre><code>&lt;Style xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:s="clr-namespace:System;assembly=mscorlib" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" TargetType="{x:Type ListBoxItem}"&gt; &lt;Style.Resources&gt; &lt;ResourceDictionary/&gt; &lt;/Style.Resources&gt; &lt;Setter Property="Panel.Background"&gt; &lt;Setter.Value&gt; &lt;SolidColorBrush&gt; #00FFFFFF &lt;/SolidColorBrush&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;Setter Property="Control.HorizontalContentAlignment"&gt; &lt;Setter.Value&gt; &lt;Binding Path="HorizontalContentAlignment" RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType=ItemsControl, AncestorLevel=1}"/&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;Setter Property="Control.VerticalContentAlignment"&gt; &lt;Setter.Value&gt; &lt;Binding Path="VerticalContentAlignment" RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType=ItemsControl, AncestorLevel=1}"/&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;Setter Property="Control.Padding"&gt; &lt;Setter.Value&gt; &lt;Thickness&gt; 2,0,0,0 &lt;/Thickness&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;Setter Property="Control.Template"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate TargetType="{x:Type ListBoxItem}"&gt; ... &lt;/ControlTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; </code></pre> <p>Note that I have removed the ControlTemplate to make it compact (I have used <a href="https://github.com/drewnoakes/style-snooper" rel="nofollow noreferrer">StyleSnooper</a> - to retrieve the style). You can see that there is a binding with a relative source set to ancestor with type ItemsControl. So in your case the ListBoxItems that are created when binding did not find their ItemsControl. Can you provide more info with what is the ItemsSource for your ListBox?</p> <p>P.S.: One way to remove the errors is to create new setters for HorizontalContentAlignment and VerticalContentAlignment in your custom Style.</p>

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.
