    <p>I've ran into some trouble trying to get partial updates to work in ASP.NET MVC2. (I think) I followed the tutorials I found online pretty closely, but the Ajax part isn't working. The controller does what it's supposed to do without errors, but the page doesn't update itself. When I refresh the page I can see the result of my action though.</p> <p>Here is the code for the user control that's supposed to update itself:</p> <pre><code>&lt;%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl&lt;Ideas.Models.Comment&gt;" %&gt; &lt;script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"&gt;&lt;/script&gt; &lt;script src="../../Scripts/MicrosoftAjax.js" type="text/javascript"&gt;&lt;/script&gt; &lt;script src="../../Scripts/MicrosoftMvcAjax.js" type="text/javascript"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; function AnimateVotebox() { $("#commentbox").animate({ fontSize: "1.5em" }, 400); } &lt;/script&gt; &lt;div id="commentbox"&gt; &lt;div class="display-label"&gt; &lt;i&gt;&lt;%: Html.ActionLink(Model.User1.UserName, "Details", "User", new { id = Model.User1.LoweredUserName.Replace(' ', '-') }, null)%&gt; zegt:&lt;/i&gt; &lt;/div&gt; &lt;div class="display-label"&gt;&lt;%:Model.text %&gt;&lt;/div&gt; &lt;% bool canPost = Ideas.Helpers.UserHelper.CanPost(HttpContext.Current); %&gt; &lt;% if (Model.CommentVotes.Count != 0) %&gt; &lt;% { %&gt; &lt;div class="display-label"&gt;&lt;%= Html.Encode(Model.UpVotes)%&gt; van de &lt;%= Html.Encode(Model.Votes)%&gt; gaan akkoord.&lt;/div&gt; &lt;% if (canPost) { %&gt; &lt;% if (Model.HasVoted((Guid)Membership.GetUser(Context.User.Identity.Name).ProviderUserKey) &lt; 0) %&gt; &lt;% { %&gt;Stem: &lt;%= Ajax.ActionLink("-", "VoteComment", "Votes", new { id = Model.id, up = false }, new AjaxOptions { UpdateTargetId = "commentbox", OnSuccess = "AnimateVotebox" }, null)%&gt; &lt;%= Ajax.ActionLink("+", "VoteComment", "Votes", new { id = Model.id, up = true }, new AjaxOptions { UpdateTargetId = "commentbox", OnSuccess = "AnimateVotebox" }, null)%&gt; &lt;% } %&gt; &lt;% else %&gt; &lt;% { %&gt;Wijzig stem: &lt;% if (Model.HasVoted((Guid)Membership.GetUser(Context.User.Identity.Name).ProviderUserKey) == 0) %&gt; &lt;% { %&gt; &lt;%= Ajax.ActionLink("-", "ChangeCommentVote", "Votes", new { id = Model.id, up = false }, new AjaxOptions { UpdateTargetId = "commentbox", OnSuccess = "AnimateVotebox" }, null)%&gt; &lt;p style="color:gray; font-size:20;""&gt;+&lt;/p&gt; &lt;% } %&gt; &lt;% else %&gt; &lt;% { %&gt; &lt;p style="color:gray; font-size:20;""&gt;-&lt;/p&gt; &lt;%= Ajax.ActionLink("+", "ChangeCommentVote", "Votes", new { id = Model.id, up = true }, new AjaxOptions { UpdateTargetId = "commentbox", OnSuccess = "AnimateVotebox" }, null)%&gt; &lt;% } %&gt; &lt;% } %&gt; &lt;% } %&gt; &lt;br /&gt; &lt;% } %&gt; &lt;% else %&gt; &lt;% { %&gt; &lt;div class="display-label"&gt;Nog geen stemmen&lt;/div&gt;&lt;br /&gt; &lt;% if (canPost) { %&gt; Stem: &lt;%= Ajax.ActionLink("-", "VoteComment", "Votes", new { id = Model.id, up = false }, new AjaxOptions { UpdateTargetId = "commentbox", OnSuccess = "AnimateVotebox" }, null)%&gt; &lt;%= Ajax.ActionLink("+", "VoteComment", "Votes", new { id = Model.id, up = true }, new AjaxOptions { UpdateTargetId = "commentbox", OnSuccess = "AnimateVotebox" }, null)%&gt; &lt;% } %&gt; &lt;% } %&gt; &lt;% if (HttpContext.Current.User.IsInRole("Moderator") || HttpContext.Current.User.IsInRole("Administrator"))%&gt; &lt;% { %&gt; &lt;%: Html.ActionLink("Geef probatie...", "ProbateUser", "Mod", new { comment = Model.id }, null) %&gt; &lt;%: Html.ActionLink("Verwijder...", "BanUser", "Mod", new { comment = Model.id }, null) %&gt; &lt;% } %&gt; &lt;/div&gt; </code></pre> <p>Note that if I don't use jQuery the problem occurs as well.</p> <p>And here's the controller:</p> <pre><code> [UserAuthorize] [Authorize] public ActionResult VoteComment(int id, bool up) { Comment comment = crep.GetComment(id); CommentVote vote = new CommentVote(); vote.isup = up; vote.user = (Guid)Membership.GetUser(User.Identity.Name).ProviderUserKey; comment.CommentVotes.Add(vote); crep.Save(); return PartialView("CommentUserControl", crep.GetComment(id)); } [UserAuthorize] [Authorize] public ActionResult ChangeCommentVote(int id, bool up) { Comment comment = crep.GetComment(id); CommentVote vote = comment.CommentVotes .Where(v =&gt; v.user == (Guid)Membership.GetUser(User.Identity.Name).ProviderUserKey &amp;&amp; v.comment == id).SingleOrDefault(); vote.isup = up; crep.Save(); return PartialView("CommentUserControl", crep.GetComment(id)); } </code></pre> <p>Don't know if this matters, but the usercontrol is loaded inside a view that's linked to a different controller than the one above. The ActionLinks work fine though and trigger actions on the VotesController.</p>

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).
