    <p>I was wondering what the best implementation for a global error (doesn't have to be errors, can also be success messages) handler would be? Let me break it down for you with an example:</p> <ol> <li>User tries to delete a record </li> <li>Deletion fails and an error is logged</li> <li>User redirects to another page</li> <li>Display error message for user (using a HtmlHelper or something, don't want it to be a specific error page)</li> </ol> <p>I'm just curious what you guys think. I've been considering TempData, ViewData and Session but they all have their pros and cons.</p> <p>TIA!</p> <p><strong>UPDATE:</strong></p> <p>I'll show an example what I exactly mean, maybe I wasn't clear enough. This is an example of a method that adds a message when user deletes a record. If user succeeds, user redirects to another page</p> <pre><code>public ActionResult DeleteRecord(Record recordToDelete) { // If user succeeds deleting the record if (_service.DeleteRecord(recordToDelete) { // Add success message MessageHandler.AddMessage(Status.SUCCESS, "A message to user"); // And redirect to list view return RedirectToAction("RecordsList"); } else { // Else return records details view return View("RecordDetails", recordToDelete); } } </code></pre> <p>And in the view "RecordsList", it would be kinda cool to show all messages (both error and success messages) in a HtmlHelper or something.</p> <pre><code>&lt;%= Html.RenderAllMessages %&gt; </code></pre> <p>This can be achieved in many ways, I'm just curious what you guys would do. </p> <p><strong>UPDATE 2:</strong></p> <p>I have created a custom error (message) handler. You can see the code if you scroll down.</p>

    1. COThat's kind of odd. In most cases, lack of an error message indicates success. Success messages are redundant in most cases. If there's an error you would stay on the same page, so I guess I still don't get the logic of what you're trying to do.

    2. COI disagree, I think it's very important to inform the user that an action has succeeded, otherwise the user can be confused. But I also understand what you mean, it's more important to inform user when failure.

    3. COAll usability studies that have been done disagree with you. It's a very highly stressed thing. Users don't want to be bothered if there isn't a 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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
