    <p>Yes. Use a VisualBrush whose Visual is a Rectangle inside a Border to combine the other two brushes.</p> <p>Something like this:</p> <pre><code>&lt;LinearGradientBrush x:Key="UnderBrush" EndPoint="0,1"&gt; &lt;GradientStop Color="#FFFF0000" Offset="0" /&gt; &lt;GradientStop Color="#00FF0000" Offset="1" /&gt; &lt;/LinearGradientBrush&gt; &lt;LinearGradientBrush x:Key="OverBrush" EndPoint="1,0"&gt; &lt;GradientStop Color="#00000000" Offset="0" /&gt; &lt;GradientStop Color="#FF000000" Offset="1" /&gt; &lt;/LinearGradientBrush&gt; &lt;VisualBrush x:Key="CombinedBrush"&gt; &lt;VisualBrush.Visual&gt; &lt;Border Background="{StaticResource UnderBrush}"&gt; &lt;Rectangle Fill="{StaticResource OverBrush}" Width="1" Height="1" /&gt; &lt;/Border&gt; &lt;/VisualBrush.Visual&gt; &lt;/VisualBrush&gt; </code></pre> <p>CombinedBrush can be used to paint your bars, and you will get the effect you describe.</p> <p><strong>Silverlight version</strong></p> <p>Since Silverlight has no VisualBrush you must build a WritableBitmap in code and use it with an ImageBrush:</p> <pre><code>&lt;ImageBrush x:Key="CombinedBrush"&gt; &lt;my:VisualBrushSimulator.Visual&gt; &lt;Border Background="{StaticResource UnderBrush}"&gt; &lt;Rectangle Fill="{StaticResource OverBrush}" Width="1" Height="1" /&gt; &lt;/Border&gt; &lt;/my:VisualBrushSimulator.Visual&gt; &lt;/ImageBrush&gt; </code></pre> <p>Here is how the VisualBrushSimulator might be implemented:</p> <pre><code>public class VisualBrushSimulator : DependencyObject { public Visual GetVisual(DependencyObject obj) { return (Visual)obj.GetValue(VisualProperty); } public void SetVisual(DependencyObject obj, Visual value) { obj.SetValue(VisualProperty, value); } public static readonly DependencyProperty VisualProperty = DependencyProperty.RegisterAttached("Visual", typeof(Visual), typeof(VisualBrushSimulator), new PropertyMetadata { PropertyChangedCallback = (obj, e) =&gt; { int width=1000; int height=1000; var bitmap = new WritableBitmap(width, height); bitmap.Render((Visual)e.NewValue, new ScaleTransform { ScaleX = width, ScaleY = height }); ((ImageBrush)obj).ImageSource = bitmap; } }); } </code></pre> <p>Note that this is not a true VisualBrush simulation, since changes to the Visual do not affect the brush.</p>

    2. COThe question was tagged both WPF and Silverlight. Without VisualBrush this is more difficult and requires some code-behind but can still be accomplished. I'll update my answer for Silverlight support.

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.

SQuiL has stopped working due to an internal error.

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