    text
    <p>I have simple ASP.NET MVC action like this : </p> <pre><code>public ActionResult Edit(EditPostViewModel data) { } </code></pre> <p>The <code>EditPostViewModel</code> have validation attributes like this : </p> <pre><code>[Display(Name = "...", Description = "...")] [StringLength(100, MinimumLength = 3, ErrorMessage = "...")] [Required()] public string Title { get; set; } </code></pre> <p>In the view I am using the following helpers : </p> <pre><code> @Html.LabelFor(Model =&gt; Model.EditPostViewModel.Title, true) @Html.TextBoxFor(Model =&gt; Model.EditPostViewModel.Title, new { @class = "tb1", @Style = "width:400px;" }) </code></pre> <p>If I do a submit on a form that this textbox is placed in a validation will be done first on client and then on service(<code>ModelState.IsValid</code>).</p> <p>Now I got a couple of questions :</p> <ol> <li><p>Can this be used with jQuery ajax submit instead? What I am doing is simply remove the form and on clicking the submit button a javascript will gather data and then run the <code>$.ajax</code>.</p></li> <li><p>Will the server side <code>ModelState.IsValid</code> work?</p></li> <li><p>How can I forward validation problem back to the client and present it as if Im using the build int validation(<code>@Html.ValidationSummary(true)</code>)?</p></li> </ol> <p>Example of Ajax call : </p> <pre><code>function SendPost(actionPath) { $.ajax({ url: actionPath, type: 'POST', dataType: 'json', data: { Text: $('#EditPostViewModel_Text').val(), Title: $('#EditPostViewModel_Title').val() }, success: function (data) { alert('success'); }, error: function () { alert('error'); } }); } </code></pre> <p>Edit 1: </p> <p>Included on page : </p> <pre><code>&lt;script src="/Scripts/jquery-1.7.1.min.js"&gt;&lt;/script&gt; &lt;script src="/Scripts/jquery.validate.min.js"&gt;&lt;/script&gt; &lt;script src="/Scripts/jquery.validate.unobtrusive.min.js"&gt;&lt;/script&gt; </code></pre>

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).
