asp.net mvc - RedirectToAction not changing URL or navigating to Index view

Question

I tried using a RedirectToAction after I have done a post to the controller and saved but the URL does not change and the redirect does not seem to work. I need to add that the redirect does enter the controller action method when I debug. It does not change the URL or navigate to the Index view.

public ViewResult Index()
{
    return View("Index", new TrainingViewModel());
}

public ActionResult Edit()
{
    // save the details and return to list
    return RedirectToAction("Index");    
}

What am I doing wrong?

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
    routes.IgnoreRoute("{resource}.js/{*pathInfo}");
    routes.IgnoreRoute("{*favicon}", new { favicon = @"(.*/)?favicon.ico(/.*)?" });

    routes.MapRoute(
        "Default", // Route name
        "{controller}/{action}/{id}", // URL with parameters
        new { controller = "Home", action = "Index", id = "" } // Parameter defaults
    );
}

jQuery calls:

this.SynchValuesToReadOnly = function() {
    window.location = $('#siteRoot').attr('href') + 'Sites/';           
};

this.OnSiteEdit = function() {
    // post back to the server and update the assessment details    
    var options = {
        target: '',
        type: 'post',
        url: '/Site/Edit',
        beforeSubmit: othis.validate,
        success: othis.SynchValuesToReadOnly
    };

    $('#uxSiteForm').ajaxSubmit(options);
};

The code you show is correct. My wild guess is that you're not doing a standard POST (e.g., redirects don't work with an AJAX post).

The browser will ignore a redirect response to an AJAX POST. It's up to you to redirect in script if you need to redirect when an AJAX call returns a redirect response.
