    <p>Why won't this work?</p> <p>In <em>generic.xaml</em> for a custom control:</p> <p>In the style applied to the custom control...</p> <pre><code>&lt;Setter Property="ChromeContent"&gt; &lt;Setter.Value&gt; &lt;Grid /&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; </code></pre> <p>...</p> <p>Later, in the control template...</p> <pre><code>&lt;ContentPresenter Grid.Column="0" x:Name="ChromeContentPresenter" Content="{TemplateBinding ChromeContent}" /&gt; </code></pre> <p>Here's the dependency property for ChromeContent...</p> <pre><code>public Object ChromeContent { get { return (Object)GetValue(ChromeContentProperty); } set { SetValue(ChromeContentProperty, value); } } public static readonly DependencyProperty ChromeContentProperty = DependencyProperty.Register("ChromeContent", typeof(Object), typeof(casPopup), null); </code></pre> <p>As you can see, it takes any object. I tried changing it to a Grid, but that did not help.</p> <p>It throws this error (from javascript): _Failed to assign to property 'System.Windows.Controls.ContentPresenter.Content'</p> <p>Oddly, the following will work fine if I remove the Grid from the setter nd just use text:</p> <pre><code>&lt;Setter Property="ChromeContent" Value="DEFAULT" /&gt; </code></pre> <p>Also, this will work too from the OnApplyTemplate method in the control class:</p> <pre><code> Grid g = new Grid(); g.Width = 100; g.Height = 25; g.Background = new SolidColorBrush(Colors.LightGray); ChromeContent = g; </code></pre> <p>I'm having a hard time understanding what is preventing the default content of a grid, defined in the generic.xaml from working. Does anyone have any knowledge on this matter?</p> <p>Many thanks in advance for your help!</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
