How to get an ASP NET MVC Ajax response to redirect to new page instead of inserting view into UpdateTargetId

Question

I am using the Ajax BeginForm to create a form the will do an ajax postback to a certain controller action and then if the action is successful  the user should get redirected to another page  if the action fails then a status message gets displayed using the AjaxOptions UpdateTargetId    using  Ajax BeginForm  Delete   null          new   userId   Model UserId            new AjaxOptions   UpdateTargetId    UserForm   LoadingElementId    DeletingDiv             new   name    DeleteForm   id    DeleteForm                HTML DELETE BUTTON         If the delete is successful I am returning a Redirect result    Authorize  public ActionResult Delete Int32 UserId        UserRepository DeleteUser UserId       return Redirect Url Action  Index    Home         But the Home Controller Index view is getting loaded into the UpdateTargetId and therefore I end up with a page within a page   Two things I am thinking about    Either I am architecting this wrong and should handle this type of action differently  not using ajax   Instead of returning a Redirect result  return a view which has javascript in it that does the redirect on the client side    Does anyone have comments on  1   Or if  2 is a good solution  what would the  redirect javascript view  look like

You can simply write in Ajax Success like below       ajax               type   POST               url    Url Action  GetUserList    User                 data    id      UID   val                  success  function  data                    window location href     Url Action  Dashboard    User                                error  function                          loader   fadeOut  slow

You can simply do some kind of ajax response filter for incomming responses with   ajaxSetup  If the response contains MVC redirection you can evaluate this expression on JS side  Example code for JS below     ajaxSetup       dataFilter  function  data  type            if  data  amp  amp  typeof data     string                 if  data indexOf  window location    gt  -1                    eval data                                   return data              If data is   window location     Acount Login   above filter will catch that and evaluate to make the redirection

The accepted answer works well except for the fact that the javascript is briefly displayed in whatever the ajax target element is  To get around this  create a partial view called  Redirect with the following code   model string  lt script gt     window location     Model    lt  script gt   Then  in the controller replace return Redirect Url Action  quot Index quot    quot Home quot      with return PartialView  quot  Redirect quot  Url Action  quot Index quot    quot Home quot      The effect is the same as the accepted answer  but without the brief artifact in the display  Place the  Redirect cshtml in the shared folder so it can be used from anywhere

I needed to do this because I have an ajax login form   When users login successfully I redirect to a new page and end the previous request because the other page handles redirecting back to the relying party  because it s a STS SSO System    However  I also wanted it to work with javascript disabled  being the central login hop and all  so I came up with this       public static string EnsureUrlEndsWithSlash string url                if  string IsNullOrEmpty url               throw new ArgumentNullException  url            if   url EndsWith                   return string Concat url                return url             public static string GetQueryStringFromArray KeyValuePair lt string  string gt    values                Dictionary lt string  string gt  dValues   new Dictionary lt string string gt             foreach var pair in values                          dValues Add pair Key  pair Value                       var array    from key in dValues Keys select string Format   0   1    HttpUtility UrlEncode key   HttpUtility UrlEncode dValues key     ToArray            return       string Join   amp    array              public static void RedirectTo this HttpRequestBase request  string url  params KeyValuePair lt string  string gt    queryParameters                            string redirectUrl   string Concat EnsureUrlEndsWithSlash url   GetQueryStringFromArray queryParameters            if  request IsAjaxRequest                HttpContext Current Response Write string Format   lt script type   text javascript   gt window location   0    lt  script gt    redirectUrl            else             HttpContext Current Response Redirect redirectUrl  true

Using JavaScript will definitely do the job   You can also use Content if this is more your style   Example   MVC Controller   HttpPost  public ActionResult AjaxMethod         return Content   http   www google co uk        Javascript    ajax       type   POST       url    AjaxMethod       success  function  redirect            window location   redirect

I m not satisfied by the best answer by the Joseph  instead of fixing the correct problem  he told that this is wrong use case  In fact there are many places for example if you are converting an old codebase to ajaxified code and there you NEED it  then you NEED it  In programming there is no excuse because its not only you who is coding its all bad and good developers and you have to work side by side  So if I don t code redirection in ajax my fellow developer can force me to have a solution for it  Just like I like to use all AMD patterned sites or mvc4  and my company can keep me away from it for a year   So let s talk on the solution now   I have done hell heck of ajax request and response handling and the simplest way I found out was to send status codes to the client and have one standard javascript function to understand those codes  If i simply send for example code 13 it might meant a redirect    So a json response like   statusCode  13  messsage    home logged-in    of course there are tons of variations proposed like   status   success   code  13  url    home logged-in   message   You are logged in now     etc   so up to your own choice of standard messages   Usually I Inherit from base Controller class and put my choice of standard responses like this  public JsonResult JsonDataResult object data  string optionalMessage                     return Json new   data   data  status    success   message   optionalMessage    JsonRequestBehavior AllowGet              public JsonResult JsonSuccessResult string message                return Json new   data       status    success   message   message    JsonRequestBehavior AllowGet              public JsonResult JsonErrorResult string message                return Json new   data       status    error   message   message    JsonRequestBehavior AllowGet              public JsonResult JsonRawResult object data                return Json data  JsonRequestBehavior AllowGet           About using   ajax intead of Ajax BeginForm I would love to use Jquery ajax and I do  but again its not me in the whole world to make decisions I have an application full of Ajax BeginForm and of course I didnt do that  But i have to live with it   So There is a success callback in begin form too  you don t need to use jquery ajax to use callbacks Something about it here Ajax BeginForm  Calls Action  Returns JSON  How do I access JSON object in my OnSuccess JS Function   Thanks

You can return a JSON with the URL and change the window location using JavaScript at client side  I prefer this way than calling a JavaScript function from the server  which I think that it s breaking the separation of concerns   Server side   return Json new  result    Redirect   url   Url Action  ActionName    ControllerName        Client side   if  response result     Redirect       window location   response url    Of course you can add more logic because there could be an error on the server side and in that case the result property could indicate this situation and avoid the redirection

While not elegant  works for me in certain situations   Controller  if  RedirectToPage      return PartialView  JavascriptRedirect   new JavascriptRedirectModel  http   www google com     else        return regular ajax partialview   Model      public JavascriptRedirectModel string location                Location   location             public string Location   get  set       Views Shared JavascriptRedirect cshtml   model Models Shared JavascriptRedirectModel   lt script type  text javascript  gt      window location     Model Location    lt  script gt

The behavior you re trying to produce is not really best done using AJAX   AJAX would be best used if you wanted to only update a portion of the page  not completely redirect to some other page   That defeats the whole purpose of AJAX really   I would suggest to just not use AJAX with the behavior you re describing   Alternatively  you could try using jquery Ajax  which would submit the request and then you specify a callback when the request completes   In the callback you could determine if it failed or succeeded  and redirect to another page on success   I ve found jquery Ajax to be much easier to use  especially since I m already using the library for other things anyway   You can find documentation about jquery ajax here  but the syntax is as follows   jQuery ajax  options      jQuery get  url  data  callback  type   jQuery getJSON  url  data  callback    jQuery getScript  url  callback    jQuery post  url  data  callback  type

You can get a non-js-based redirection from an ajax call by putting in one of those meta refresh tags  This here seems to be working   return Content   lt meta http-equiv   refresh   content   0 URL       Url Action  Index    Home            gt      Note  I discovered that meta refreshes are auto-disabled by Firefox  rendering this not very useful

You can use JavascriptResult to achieve this   To redirect   return JavaScript  window location    http   www google co uk       To reload the current page   return JavaScript  location reload true       Seems the simplest option
