<p>I finally found the solution to the problem. I implemented it with AJAX and ended up with the following code:</p> <p>_Index.cshtml</p> <pre><code><header> <h2>Subscribe</h2> </header> <p>Subscribe to my e-mail newsfeed.</p> <div id="subscription-form"> @{Html.RenderPartial("_Form");} </div> </code></pre> <p>_Form.cshtml</p> <pre><code>@using Blog.Models.Entities @model Subscriber @{ AjaxOptions ajaxOptions = new AjaxOptions { LoadingElementId = "loading", LoadingElementDuration = 2000, HttpMethod = "Post", UpdateTargetId = "subscription-form" }; } <div id="loading" style="display: none;"> <p>Processing request...</p> </div> @using (Ajax.BeginForm("Index", "Subscription", ajaxOptions)) { <div class="editor-label">@Html.LabelFor(subscriber => subscriber.Email)</div> <div class="editor-field ">@Html.EditorFor(subscriber => subscriber.Email)</div> @Html.ValidationMessageFor(subscriber => subscriber.Email) <input type="submit" value="Subscribe" /> } </code></pre> <p>_Succes.cshtml</p> <pre><code>@using Blog.Models.Entities @model Subscriber <p id="subscription-result">@ViewBag.Result</p> </code></pre> <p>And the following controller action methods:</p> <pre><code>public ActionResult Index() { return PartialView("_Index"); } [HttpPost] public PartialViewResult Index(Subscriber subscriber) { if (ModelState.IsValid) { Subscriber foundSubscriber = _repository.Subscribers.Where(s => s.Email.Equals(subscriber.Email)).FirstOrDefault(); if (foundSubscriber != null) { ModelState.AddModelError("Email", "This e-mail address has already been added."); return PartialView("_Form", subscriber); } _repository.SaveSubscriber(subscriber); ViewBag.Result = "Succesfully subscribed to the newsletter."; return PartialView("_Succes", subscriber); } ModelState.AddModelError("Email", "Please provide a valid e-mail address."); return PartialView("_Form", subscriber); } </code></pre> <p>I hope this will help anyone trying to achieve the same in the future. BTW, I found the solution on this blog: <a href="http://xhalent.wordpress.com/2011/02/05/using-unobtrusive-ajax-forms-in-asp-net-mvc3/" rel="nofollow">http://xhalent.wordpress.com/2011/02/05/using-unobtrusive-ajax-forms-in-asp-net-mvc3/</a>.</p>

Guidance

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.
