I'm using jquerymobile and asp.net MVC3 razor. I'm somewhat new to this, but figuring things out, I have a very basic route table, with just the ignore route for .axd resources and a default route:
routes.MapRoute(
"Default",
"{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = "", UrlParameter.Optional }
);
I have an action link that works in an .ascx page:
#Html.ActionLink("Log On", "LogOn", "Account", null, new { #class = "ui-btn-right" })
Now, when I get to the LogOn page, and I complete the account verification, I need to send them to the home page, /Home/Home which works if I type it in the address bar, but I can't seem to get my redirect working in the account controller: return RedirectToAction("Home", "Home");
Thanks for any help!
It sounds like maybe you're posting your form from /Account/LogOn via ajax. That means that when you return RedirectToAction("Home", "Home");, the page wouldn't change. So you just need to not use ajax on the form submit. If my guess is wrong, please post more code so we can get an idea of what the problem is.
It appears from the documentation that jQuery mobile handles form posts via ajax automatically. To prevent this, add the data-ajax="false" attribute to the form element. Documentation here: http://jquerymobile.com/test/docs/forms/forms-sample.html
Given what's written in documentation, could you put your code into a form element and setting its action property to /Account/LogOn ? In order to do that, you may have to convert your ActionLink into a button.
You can check for ajax request in controller:
if(Request.IsAjaxRequest())
{
//send json object and do navigate in client
return Json(new {IsLogged = true});
}
else
{
//send redirect html code to browser
return RedirectToAction("Home", "Home");
}
and in client side, check for json result if you post form by jQuery ajax.
I'm not use jquerymobile so I don't know how it work in client side.

I am building a web application using .net MVC 4.
I have ajax form to edit data.
If the user is idle for 15 mins it will expire the session of the user. When that happens if user click edit button it loads the login page inside the partial content hence now the current session expires.
Edit Link - cshtml code
#Ajax.ActionLink("Edit", MVC.Admin.Material.ActionNames.TagEditorPanel, MVC.Admin.Material.Name, new { isView = "false", id = Model.ID.ToString() }, new AjaxOptions { HttpMethod = "GET", UpdateTargetId = "materialTagBox", InsertionMode = InsertionMode.Replace }, new { #class = "editlinks" })
Controller/Action Code
[Authorize]
public virtual ActionResult TagEditorPanel(bool isView, int id)
{
//do something
return PartialView(MVC.Admin.Material.Views._tag, response);
}
Web.config
<authentication mode="Forms">
<forms loginUrl="~/Account/Login" timeout="2880" />
</authentication>
I understand why it is happening. I don't know how to resolve it. I want to prevent it and I want to redirect user to login page directly. How can I achieve this?
Thanks inadvance..!!!
Maybe a hacky answer, but you can change the redirect location in forms authentication to a page that sets the window location to the login page with javascript.
Web Config
<authentication mode="Forms">
<forms loginUrl="~/Account/RedirectToLogin" timeout="2880" />
</authentication>
Account Controller
public ActionResult RedirectToLogin()
{
return PartialView("_RedirectToLogin");
}
_RedirectToLogin View
<script>
window.location = '#Url.Action("Login", "Account")';
</script>
The issue is your call is intercepted by [Authorize] and sends the login page even before your action method code is called. One way to sort this out is to create a custom action filter to check the timeout and do a hard redirect to login page. Following post has a good write up which may help you in creating and registering the filter

Best of luck
You may want to check the answer to this (similar) question.
ASP.NET MVC Partial view ajax post?
Basically it says that you should avoid making ajax calls to functions that may redirect because of this and other problems.
You can avoid the problem that you are having by authorizing / checking the expiration manually in your function, and then returning redirect information that can be applied to the whole page.
I have used this approach, and it works well.
Inspired by kramwens answer, one could avoid making an extra RedirectToLogin view (and controller action) and just put the following in you original Login view:
<script>
if (window.location != '#string.Format("{0}://{1}{2}",Request.Url.Scheme, Request.Url.Authority,Url.Content("~/Account/Login"))')
window.location = '#Url.Action("Login", "Account")';
</script>
This tests the current window.location and if it is not as expected, it sets it as expected.
I know, my js is a bit hacky and crappy, but it does the work :)
I Have simple way find for partial view session expired.
Simple One Action created then this view java script windows.load() call then url will be pass to this login page.
//in Controller one Action Created.
<script type="text/javascript">
window.location = '#Url.Action("Login", "LogIn")';
</script>
Public ActionResult SessionExpire()
{
return View();
}
//Redirect to login from partail view after session is null:
return Redirect("~/OrderPlace/Sessionview");
My solution is to use some c# code whenever possible. I can get the controller and view name, check to see of they are what they should be, and if not redirect to the proper.
var controllerName = ViewContext.RouteData.GetRequiredString("controller");
var actionName = ViewContext.RouteData.GetRequiredString("action");
I then use the following to go to the proper URL:
if (controllerName != "members" && actionName != "logon")
{
#{ Response.Redirect("~/Members/Logon");}
}
So there are lots of questions out there about this whole "IE opens a download file dialog for Json data returned via Ajax" (like this one or this one), but I have not found any answers for those who use Unobtrusive Ajax.
We do a simple Ajax.BeginForm like this:
Ajax.BeginForm("Login", "Account", new { ReturnUrl = ViewBag.ReturnUrl },
new AjaxOptions { UpdateTargetId = "ContentContainer", OnSuccess = "JsonCheckRedirect" },
new { id = "form1" }
)
This posts the form with Content Type of "application/x-www-form-urlencoded; charset=UTF-8". The Controller processes the form, and if there is an error, it returns a PartialView with Content Type "text/html", and that HTML gets put into the ContentContainer (because of the "UpdateTargetId" property in the AjaxOptions).
If there is no error, and the user logged in successfully, it returns Json with the URL they should be redirected to. So in the Controller, it's just simply this:
return Json(new { Url = returnUrl });
Except that we just had a user notify us that in IE8, this is causing the download dialog to pop up. After reading all these other questions with the same issue, I understand why this is happening, but the fix for those situations is to use this Json return instead:
return Json(new { Url = returnUrl }, "text/html");
The problem is that when I return like this, I guess Unobtrusive Ajax sees that the response from the server is HTML, and it replaces the content in the UpdateTargetId container. It does not do this when the server responds with "application/json".
Is there any way around this?
(do I need to explain anything further?)
If you return the url like that, you are going to need to override the Success handler and check the result to see if it has the Url property and then putting the result into window.location.
Personally, rather than returning a new Json result, I would send back a 302 which should make the ajax handler redirect you.
This happens in the bowels of jQuery if memory serves, so you don't need to change anything.
So rather than returning that json result on a successful login, try using a redirectToRoute result instead and send them to the page you want them to go to.
I'm using Fancybox 1.3.4 with ASP.NET MVC 3.
I have following link :
<a id="various" href="Like/List/#feed.Id" class="petlikeCount liked">#feed.LikeCount</a>
and also jquery :
<script type="text/javascript">
$(document).ready(function () {
$("#various").fancybox({
type: 'ajax'
});
});
</script>
Controller action in Like controller :
public JsonResult List(int id)
{
return Json("success", JsonRequestBehavior.AllowGet);
}
My problem is that Like/List is never called (checked with the breakpoint) and fancybox just appears and show content of "parent" page....
I also tried with iframe content returning pure html back, but I'm getting same strange behavior as above.
Thank you in advance!
I'd recommend you using HTML helpers instead of hardcoding anchors:
#Html.ActionLink(
feed.LikeCount,
"List",
"Like",
new { id = feed.Id },
new { id = "various", #class = "petlikeCount liked" }
)
Another thing that you should make sure is that the feed.Id is actually an integer variable so that when the List action is invoked it is correctly passed this id.
So your url should look something like this: /List/Like/123. And then assuming tat you have kept the default route and haven't messed up with some custom routes, the List action should be called and passed the correct id as argument.
Also I would very strongly recommend you using a javascript debugging tool in your browser such as FireBug in which you will be able to see any potential errors with your scripts as well as the actual AJAX requests being sent which will allow you to more easily debug such problems.
My first post...
When I use RedirectToAction the url in the browser doesn't change. How can I achieve this?
I'm switching over to ASP.NET MVC 3.0 (also using jQuery Mobile) after 10+ years using web forms. I'm about 8 weeks into it, and after several books and scouring Google for an answer, I'm coming up dry.
I have a single route defined in Global.asax:
routes.MapRoute(
"Routes",
"{controller}/{action}/{id}",
new { controller = "Shopping", action = "Index", id = UrlParameter.Optional }
I have a ShoppingController with these actions:
public ActionResult Cart() {...}
public ActionResult Products(string externalId) {...}
[HttpPost]
public ActionResult Products(List<ProductModel> productModels)
{
// do stuff
return RedirectToAction("Cart");
}
The url when I do a get and post (with the post having the RedirectToAction) is always:
/Shopping/Products?ExternalId=GenAdmin
After the post and RedirectToAction I want the url in the browser to change to:
/Shopping/Cart
I've tried Redirect, and RedirectToRoute but get the same results.
Any help would be greatly appreciated.
[Update]
I found that jQuery Mobile AJAX posts are the culprit here. If I turn off jQuery Mobile's AJAX it works.
<script type="text/javascript" src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script type="text/javascript">
// do not handle links via ajax by default
$(document).bind("mobileinit", function () { $.mobile.ajaxEnabled = false; });
</script>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0rc2/jquery.mobile-1.0rc2.min.css" />
The ordering of the above scripts is important. I had to include the script to jQuery first, then include the script to disable jQuery Mobile's use of AJAX and then include the script to jQuery Mobile.
I'd still like to find a way to use AJAX and have the url update properly. Or at the least be able to call jQuery Mobile's "loading" message (or bake my own).
I think I've found an answer. Buried deep in the jQuery Mobile documentation, there is information about setting the data-url on the div with data-role="page". When I do this, I get the nice jQuery Mobile AJAX stuff (page loading message, page transitions) AND I get the url in the browser updated correctly.
Essentially, this is how I'm doing it...
[HttpPost]
public ActionResult Products(...)
{
// ... add products to cart
TempData["DataUrl"] = "data-url=\"/Cart\"";
return RedirectToAction("Index", "Cart");
}
Then on my layout page I have this....
<div data-role="page" data-theme="c" #TempData["DataUrl"]>
On my HttpPost actions I now set the TempData["DataUrl"] so for those pages it gets set and is populated on the layout page. "Get" actions don't set the TempData["DataUrl"] so it doesn't get populated on the layout page in those situtations.
The only thing that doesn't quite work with this, is when you right-click... view source... in the browser, the html isn't always for the page you are on, which isn't unusual for AJAX.
Not sure if it is still actual, but in my case I wrote following helper method
public static IHtmlString GetPageUrl<TModel>(this HtmlHelper<TModel> htmlHelper, ViewContext viewContext)
{
StringBuilder urlBuilder = new StringBuilder();
urlBuilder.Append("data-url='");
urlBuilder.Append(viewContext.HttpContext.Request.Url.GetComponents(UriComponents.PathAndQuery, UriFormat.UriEscaped));
urlBuilder.Append("'");
return htmlHelper.Raw(urlBuilder.ToString());
}
And then use it as follows:
<div data-role="page" data-theme="d" #Html.GetPageUrl(ViewContext) >
This way I don't need for every redirect action store a TempData. Worked for me fine both for Redirect and RedirectToAction. This would not work properly in case if you use method "View()" inside controller and return different view name, which will change UI, but will retain url.
Hope it helps

David, this was a big help to me. I just wanted to add that in my case I had to use the following format to get the Url to display in the correct form as my other url's:
TempData["DataUrl"] = "data-url=/appName/controller/action";
return RedirectToAction("action", "controller");
As a side note, I also found that when assigning the value to TempData["DataUrl"] I was able to leave out the escaped quotes and enter it exactly as above and it seems to be working fine for me. Thanks again for your help.
There is an issue on github
https://github.com/jquery/jquery-mobile/issues/1571
It has a nice solution without the need of TempData
since I'm new in jquery, can you tell me how to redirect a page to another action method ?
I develop a MVC web application. I use jquery post method to do some validation, and when it return true, it will be redirect page to another one.
My problem is..when when I redirect page using window.location, it's works well in IE (IE 9). but didn't work on firefox & chrome.
So, I try to using jquery post method to redirect page from action method in my controller. I call redirect post method in a jquery post call back.
it is my code :
$.post(posturl, formData, function (result) {
if (result == 'True') {
$.post("/Controller/RedirectMethod", {_Action: 'Index', _Controller: 'Home'}, null);
}
else
alert('failed');
}
);
and this is my RedirectMethod :
[HttpPost]
public ActionResult RedirectMethod(string _Action, string _Controller)
{
return RedirectToAction(_Action, _Controller);
}
so how I should create a nested post in another post callback ?
or there is another way to redirect page ?
thanks,
You won't be able to do a RedirectToAction inside an Ajax request.
If you need the web page to change to a different location inside the Ajax response, use window.location as Ben suggested.
One thing to bear in mind is that you'll need to remove the 'HttpPost' action filter.
