    <p>Maybe I'm missing something, but MVC has a default global <code>ErrorHandlerAttribute</code> that uses custom errors. This is explained quite well <a href="http://www.dotneat.net/2011/04/12/ErrorHandlingInASPNETMVC3.aspx" rel="noreferrer">here</a>. </p> <pre><code>public static void RegisterGlobalFilters(GlobalFilterCollection filters) { filters.Add(new HandleErrorAttribute()); } </code></pre> <p>All you need to do is turn on <code>custom errors</code> in the config, and then setup custom error redirects, preferably to a static <code>HTML</code> file (in case there's errors with the app). </p> <pre><code>&lt;customErrors mode="On" defaultRedirect="errors.htm"&gt; &lt;error statusCode="404" redirect="errors404.htm"/&gt; &lt;/customErrors&gt; </code></pre> <p>If you prefer could also point to a custom <code>Controller</code> to display the errors. In the following example I've just used the default routing to a <code>Controller</code> named <code>Error</code>, with an action called <code>Index</code>, and string parameter named <code>id</code> (to receive the errorcode). You could of course use any routing you desire. Your example isn't working because you are trying to link directly into the <code>Views</code> directory without going via a <code>Controller</code>. MVC .NET doesn't serve requests to the <code>Views</code> folder directly.</p> <pre><code>&lt;customErrors mode="On" defaultRedirect="/error/index/500"&gt; &lt;error statusCode="404" redirect="/error/index/404"/&gt; &lt;/customErrors&gt; </code></pre> <p>The <a href="http://weblogs.asp.net/fredriknormen/archive/2007/11/22/asp-net-mvc-framework-handling-exception-by-using-an-attribute.aspx" rel="noreferrer">ErrorHandlerAttribute</a> can also be used extensively with <code>Controllers/Actions</code> to redirect errors to named <code>Views</code> related to the <code>Controller</code>. For example to show the <code>View</code> named <code>MyArgumentError</code> when a exception of type <code>ArgumentException</code> occurs you could use:</p> <pre><code>[ControllerAction,ExceptionHandler("MyArgumentError",typeof(ArgumentException))] public void Index() { // some code that could throw ArgumentExcepton } </code></pre> <p>Of course another option is to update the stock <code>Error</code> page in <code>Shared</code>.</p>

    1. COThe problem is that IIS express already handles those other status codes (not the 500), so what you're suggesting doesn't always work (depends on the IIS setup). IIS just displays its own page, and we never make it through to the view in asp.

    2. COTrue, that's just IIS config though which is a different issue. The MVC error handling should be done as above.

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).
