    <p>Providing a custom component turned out to be the best solution. I use it like this in my code</p> <pre><code>&lt;Controls:Arc Center="{Binding Path=PreviousMousePositionPixels}" Stroke="White" StrokeDashArray="4 4" SnapsToDevicePixels="True" StartAngle="0" EndAngle="{Binding Path=DeltaAngle}" SmallAngle="True" Radius="40" /&gt; </code></pre> <p><code>SmallAngle</code> when <code>true</code> will render the small angle between the points irrespective of order of <code>StartAngle</code> and <code>EndAngle</code>. When <code>SmallAngle</code> is <code>false</code> the arc is rendered counter clockwise.</p> <p>The implementation is</p> <pre><code>using System; using System.Collections.Generic; using System.Windows; using System.Windows.Media; using System.Windows.Shapes; public sealed class Arc : Shape { public Point Center { get =&gt; (Point)GetValue(CenterProperty); set =&gt; SetValue(CenterProperty, value); } // Using a DependencyProperty as the backing store for Center.

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).
