    <p>The following code throws a cryptic System.ArgumentException from the RenderAsync method "Value does not fall within the expected range." If on the other hand my Canvas is part of a visible XAML tree it works. Is it impossible to render some XAML that isn't displayed on screen?</p> <pre><code>Canvas c = new Canvas(); c.Width = 40; c.Height = 40; c.Background = new SolidColorBrush(Color.FromArgb(0xff, 0x80, 0xff, 0x80)); RenderTargetBitmap x = new RenderTargetBitmap(); await x.RenderAsync(c); </code></pre> <p>I almost thought this answer would work, but no luck, I guess it only applies to WPF: <a href="https://stackoverflow.com/questions/1877115/create-wpf-element-offscreen-and-render-to-bitmap">Create WPF element offscreen and render to bitmap</a></p> <p><strong>UPDATE:</strong></p> <p>So far my best idea is to put the Canvas I want to render to into the currently visible page but place it beneath what is normally the root UIElement that fills the screen so it isn't visible to the user:</p> <pre><code>&lt;Grid&gt; &lt;Canvas x:Name="HiddenCanvas"/&gt; &lt;Grid x:Name="mainElement" Background="{StaticResource ApplicationPageBackgroundThemeBrush}"&gt; &lt;/Grid&gt; &lt;/Grid&gt; </code></pre> <p>It isn't beautiful but it seems to work. Lets see if anyone can do better</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).
