    <p>After some procrastination I finally set about coding a solution to my original issue.</p> <p>My solution uses a custom <code>TraceListener</code> (originally suggested by John) that logs to an output window. The output window is automatically displayed and bought to the foreground when an error occurs.</p> <p>Here is my <code>TraceListener</code>:</p> <pre><code>public class ErrorLogTraceListener : TraceListener { public override void Write(string message) { ... } public override void WriteLine(string message) { ... } } </code></pre> <p><code>TraceListener</code> is defined in System.Diagnostics.</p> <p>The custom <code>TraceListener</code> must be hooked into the system to be used. The official way to do this is to set something in the registry and then use the <code>App.config</code> file to configure the <code>TraceListener</code>. </p> <p>However I found that there is a much easier way to do this programmatically:</p> <pre><code>ErrorLogTraceListener listener = new ErrorLogTraceListener(); PresentationTraceSources.Refresh(); PresentationTraceSources.DataBindingSource.Listeners.Add(listener); PresentationTraceSources.DataBindingSource.Switch.Level = SourceLevels.Error; </code></pre> <p><code>PresentationTraceSources</code> is also defined in <code>System.Diagnostics</code>.</p> <p>For more information on trace sources see Mike Hillberg's <a href="http://blogs.msdn.com/mikehillberg/archive/2006/09/14/WpfTraceSources.aspx" rel="nofollow noreferrer">blog</a>.</p> <p>Bea Stollnitz has some useful info on her <a href="http://www.beacosta.com/blog/?p=52" rel="nofollow noreferrer">blog</a>.</p>

    1. COI found that this only catches errors when the debugger is attached. When the debugger is not attached then WPF doesn't emit the errors in the first place.. (?) Has anyone else experienced this?

    2. COOn further investigation it's just the flushing behaviour that is altered when the debugger is attached. Use `System.Diagnostics.Trace.AutoFlush = true;` fixed our problem.

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).
