Ajax.BeginForm OnSuccess not firing

Add reference to the following js libraries:

• jquery-{version}.min.js
• MicrosoftAjax.js
• MicrosoftMvcAjax.js
• jquery.validate.min.js
• jquery.validate.unobtrusive.js
• jquery.unobtrusive-ajax.js

Assuming you have a brand new project, you need to do the following things to get this working. The ASP.NET MVC template does not support unobtrusive AJAX out of the box:

1. Add the "Microsoft.jQuery.Unobtrusive.Ajax" package from Nuget into your project. You can do this by right-clicking on the project and choosing "Manage Nuget Packages."

2. Add "jquery.unobtrusive-ajax.js" to your page. If you're using the "bundling" feature in System.Web.Optimization, one easy way would be to add it to the jQuery bundle:

   bundles.Add(new ScriptBundle("~/bundles/jquery")
       .Include("~/Scripts/jquery-{version}.js")
       .Include("~/Scripts/jquery.unobtrusive-ajax.js"));
   

   You can also just add a <script> tag that points to the script.

Assuming the page is loading jQuery and jquery.unobtrusive-ajax.js, the code you posted should work.
