    <p>The value of previousDiv when i run the jQuery shown below is always: [ ]. I have tried several variations of the .prev() function including .prev('div'), and .prev() all with the same result.</p> <p>Here is the jQuery:</p> <pre><code>$('.AddToRole').click(function(evt) { var path = document.URL; var thisUser = this.value; var previousControl = $(this).prev('.AvailableRoles'); var newUserRole = previousControl[0].options[previousControl[0].selectedIndex].text; var newHTML = "&lt;button id='button_DeleteRole_" + newUserRole +"' class='DeleteRole' value=" + newUserRole + "&gt;X&lt;/button&gt;&amp;nbsp;&lt;label id='label_DeleteRole_" + newUserRole + "'&gt;" + newUserRole + "&lt;/label&gt;&lt;br /&gt;"; var previousDiv = $(this).prev('#DisplayUserRoles'); $(previousDiv).append(newHTML); </code></pre> <p>Here is the html/razor code in the page:</p> <pre><code>&lt;div&gt; @* Display user email. *@ &lt;h3&gt;@user.Email&lt;/h3&gt; &lt;div&gt; &lt;div id="DisplayUserRoles"&gt; @{ @* Display roles user belongs to. *@ foreach (var role in userRoles) { @* Remove user from role button. *@ &lt;button id="button_RemoveFromRole_@user.Email" value="@role.RoleName" onclick="RemoveUserFromRole(this);"&gt;X&lt;/button&gt; &lt;label id="label_RemoveFromRole_@role.RoleName"&gt;@role.RoleName&lt;/label&gt; &lt;br /&gt; } } &lt;/div&gt; &lt;br /&gt; @{ @* Create ListBox with roles user does not belong to. *@ var items = rolesUserDoesNotBelongTo.Select(i =&gt; new SelectListItem { Value = i.RoleName, Text = i.RoleName }); string listBoxId = "listboxRoles_"; listBoxId = listBoxId + user.Email; } @Html.ListBox(listBoxId, items, new { @class = "AvailableRoles" }) @* Add user to role button. *@ &lt;button id="button_AddToRole_@user.Email" class="AddToRole" value="@user.Email"&gt;Add To Role&lt;/button&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>For the end result I am trying to add another button and label just before the closing div tag for #DisplayUserRoles.</p>

    1. COprobably just a typo: you're not closing the `click` event. `})`

    2. COWe would need to see your actual HTML (from View/Source in the browser), not the template language to know how to traverse your HTML.

    3. COI think the problem is that .prev() only selects the siblings of the same element type. In your case $(this) is a button so it has no other sibling and .prev() returns [].

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).
