    <p>I was never able to get CustomErrors in a web.config and MVC to play nice together, so I gave up. I do this instead.</p> <p>In global.asax:</p> <pre><code>protected void Application_Error() { var exception = Server.GetLastError(); var httpException = exception as HttpException; Response.Clear(); Server.ClearError(); var routeData = new RouteData(); routeData.Values["controller"] = "Errors"; routeData.Values["action"] = "General"; routeData.Values["exception"] = exception; Response.StatusCode = 500; if (httpException != null) { Response.StatusCode = httpException.GetHttpCode(); switch (Response.StatusCode) { case 403: routeData.Values["action"] = "Http403"; break; case 404: routeData.Values["action"] = "Http404"; break; } } // Avoid IIS7 getting in the middle Response.TrySkipIisCustomErrors = true; IController errorsController = new GNB.LG.StrategicPlanning.Website.Controllers.ErrorsController(); HttpContextWrapper wrapper = new HttpContextWrapper(Context); var rc = new RequestContext(wrapper, routeData); errorsController.Execute(rc); } </code></pre> <p>In ErrorsController:</p> <pre><code>public class ErrorsController { public ActionResult General(Exception exception) { // log the error here return View(exception); } public ActionResult Http404() { return View("404"); } public ActionResult Http403() { return View("403"); } } </code></pre> <p>In web.config:</p> <pre><code>&lt;customErrors mode="Off" /&gt; </code></pre> <p>That's worked for me no matter where or how the error is created. 401 isn't handled there right now but you could add it pretty easily.</p>

    1. COthanks for the answer - however I have seen this approach and for some reason it did not appeal to me.

    2. CO@Ahmad me neither, but it works. :) I found trying to set it up with CustomErrors in web.config that depending on where/how the error is thrown, it doesn't always work.

    3. COGreat answer - except I would also add an if (!HttpContext.Current.IsDebuggingEnabled) around the block in Application_Error so the errors still show while debugging.

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).
