    <p>You can use reflection to enumerate all classes in an assembly, and filter only classes inherit from Controller class.</p> <p>The best reference is <a href="http://aspnet.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=24471" rel="noreferrer">asp.net mvc source code</a>. Take a look of the implementations of <a href="http://aspnet.codeplex.com/sourcecontrol/changeset/view/23011?projectName=aspnet#266456" rel="noreferrer">ControllerTypeCache</a> and <a href="http://aspnet.codeplex.com/sourcecontrol/changeset/view/23011?projectName=aspnet#266437" rel="noreferrer">ActionMethodSelector</a> class. ControllerTypeCache shows how to get all controller classes available. </p> <pre><code> internal static bool IsControllerType(Type t) { return t != null &amp;&amp; t.IsPublic &amp;&amp; t.Name.EndsWith("Controller", StringComparison.OrdinalIgnoreCase) &amp;&amp; !t.IsAbstract &amp;&amp; typeof(IController).IsAssignableFrom(t); } public void EnsureInitialized(IBuildManager buildManager) { if (_cache == null) { lock (_lockObj) { if (_cache == null) { List&lt;Type&gt; controllerTypes = GetAllControllerTypes(buildManager); var groupedByName = controllerTypes.GroupBy( t =&gt; t.Name.Substring(0, t.Name.Length - "Controller".Length), StringComparer.OrdinalIgnoreCase); _cache = groupedByName.ToDictionary( g =&gt; g.Key, g =&gt; g.ToLookup(t =&gt; t.Namespace ?? String.Empty, StringComparer.OrdinalIgnoreCase), StringComparer.OrdinalIgnoreCase); } } } } </code></pre> <p>And ActionMethodSelector shows how to check if a method has desired attribute.</p> <pre><code>private static List&lt;MethodInfo&gt; RunSelectionFilters(ControllerContext controllerContext, List&lt;MethodInfo&gt; methodInfos) { // remove all methods which are opting out of this request // to opt out, at least one attribute defined on the method must return false List&lt;MethodInfo&gt; matchesWithSelectionAttributes = new List&lt;MethodInfo&gt;(); List&lt;MethodInfo&gt; matchesWithoutSelectionAttributes = new List&lt;MethodInfo&gt;(); foreach (MethodInfo methodInfo in methodInfos) { ActionMethodSelectorAttribute[] attrs = (ActionMethodSelectorAttribute[])methodInfo.GetCustomAttributes(typeof(ActionMethodSelectorAttribute), true /* inherit */); if (attrs.Length == 0) { matchesWithoutSelectionAttributes.Add(methodInfo); } else if (attrs.All(attr =&gt; attr.IsValidForRequest(controllerContext, methodInfo))) { matchesWithSelectionAttributes.Add(methodInfo); } } // if a matching action method had a selection attribute, consider it more specific than a matching action method // without a selection attribute return (matchesWithSelectionAttributes.Count &gt; 0) ? matchesWithSelectionAttributes : matchesWithoutSelectionAttributes; } </code></pre>

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).
