    <p>Have a look at this <a href="http://blogs.us.sogeti.com/swilliams/2009/05/14/mvc-ndash-using-antiforgerytoken-over-ajax/" rel="noreferrer">blog post</a>.</p> <blockquote> <p>Say you have an Action method like this:</p> <p><code>[AcceptVerbs(HttpVerbs.Post), ValidateAntiForgeryToken] public ActionResult DeleteAccount(int accountId) { // delete stuff }</code></p> <p>And you call it via:</p> <p><code>$.post('/home/DeleteAccount', { accountId: 1000 }, function() { alert('Account Deleted.'); });</code></p> <p>Since the POST does not include the AntiForgeryToken, it will fail.</p> <p>Fortunately, it doesn’t take much brainpower to fix this. All the client side component of AntiForgeryToken does is put the token in a basic hidden field. So, you just need to pull that data out and include it in your AJAX call.</p> <p><code>var token = $('input[name=__RequestVerificationToken]').val();</code></p> <p><code>$.post('/home/DeleteAccount', { accountId: 1000, '__RequestVerificationToken': token }, function() { alert('Account Deleted.'); });</code></p> <p>Do note that if you have multiple forms on the page with multiple AntiForgeryTokens, you will have to specify which one you want in your jQuery selector. Another gotcha is if you are using jQuery’s <code>serializeArray()</code> function, you’ll have to add it a bit differently:</p> <p><code>var formData = $('#myForm').serializeArray(); var token = $('input[name=__RequestVerificationToken]').val(); formData.push({ name: '__RequestVerificationToken', value: token });</code></p> <p><code>$.post('/home/DeleteAccount', formData, function() { alert('Account Deleted.'); });</code></p> </blockquote> <p>Update: The link has been fixed.</p>

    2. COYou don't need formData.push({ name: '__RequestVerificationToken', value: token }); since serializeArray() will return all inputs in the form, that include __RequestVerificationToken hidden field.

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).
