    <p>My Controller creates a list of links like this</p> <pre><code>&lt;ul id="MainMenu"&gt; @foreach (var item in Model.MenuItems) { &lt;li&gt;@Ajax.ActionLink(item.Caption, item.ActionName, item.ControllerName, new AjaxOptions { UpdateTargetId = "pageBody", OnBegin = "BeginUpdatePage", OnComplete = "EndUpdatePage", OnFailure = "FailUpdatePage" }) &lt;/li&gt; } &lt;/ul&gt; </code></pre> <p>I have some javascript like this</p> <pre><code>function BeginUpdatePage() { $("#MainMenu li").removeClass('selected'); $(this).parent().addClass('selected'); $("#pageBody").fadeTo('slow', 0.5); } function EndUpdatePage() { $("#pageBody").fadeTo('slow', 1); } function FailUpdatePage() { alert('There has been an error loading this page please try again.'); } </code></pre> <p>in the BeginUpdatePage function line 1 and 3 execute fine, but line 2 "$(this).parent().addClass('selected');" does not visiably do anything... (I have declared that class in my css).</p> <p>I have looked at Jquery docs (<a href="http://api.jquery.com/jQuery.ajax/" rel="nofollow noreferrer">Jquery.ajax()</a>) it says that "this" is the element that was clicked. I have also checked in "jquery.unobtrusive-ajax.js" that was in my project by default. This file also passes "this" when executing my function.</p> <pre><code>"result = getFunction(element.getAttribute("data-ajax-begin"), ["xhr"]).apply(this,arguments);" </code></pre> <p>What am I doing wrong here... I have seen <a href="http://www.asp.net/mvc/tutorials/iteration-7-add-ajax-functionality-cs" rel="nofollow noreferrer">other examples</a> that have used this technique but I have been failing all day!</p> <p>How can I get to the element that was clicked, inside my Begin, complete functions.</p>

    2. COMicrosoft AJAX is different from JQuery, so I think you are looking at the wrong documentation.

    3. CO+1 for checking Firebug. You can break on your callback scripts and check `this` in the console.

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).
