  • asp.net mvc cookies not being sent back

    - by brian b
    My application at mysubdomain.mydomain.com needs to set a cookie that contains some user session information. They log in at a https page. We authenticate them and set some session info in a cookie. We do this in a helper library that takes in the controller context contextBase.Response.Cookies[CookiePayload.CookieName].Value = encryptedTicket; contextBase.Response.Cookies[CookiePayload.CookieName].Expires = cookieExpires; contextBase.Response.Cookies[CookiePayload.CookieName].Domain= ConfigHelper.CookieDomain; contextBase.Response.Cookies[CookiePayload.CookieName].HttpOnly=true; We do a quick redirect in the controller (to a non https page): this.ControllerContext.HttpContext.Response.Redirect(redirectTo, false); return null; The cookie appears in the response (according to firebug's net tab). But neither fireforx nor ie send the cookie on subsequent gets. We are setting the cookie domain to mydomain.com even though the site is mysubdomain.mydomain.com. Skipping the redirect command has no effect, nor does changing the cookie value. I'm baffled. Thanks for any suggestions.

  • Iterating throgh mvc model lists using javascript

    - by kapil
    I want to iterate through my model values. Following is what I did to achieve this. But the varible count never increments. How can I increment it to iterate throgh my model values? <script language="javascript" type="text/javascript"> function AddStudentName() { var StudentName = document.getElementById('txtStudentName').value; StudentName= StudentName.replace(/^\s+|\s+$/g, ''); if(StudentName!= null) { <%int count = 0; %> for(var counter = 0; parseInt(counter)< parseInt('<%=Model.StudentInfo.Count%>',10); counter++) { alert('<%=count%>'); if('<%=Model.StudentInfo[count].StudentName%>' == StudentName) { alert("A student with new student name already exists."); return false; } <%count = count +1;%> } } } </script> thanks, Kapil

  • ASP.NET MVC Model Binding

    - by Noel
    If i have a Controller Action that may recieve both HTTP GET and HTTP POST from a number of different sources with each source sending different data e.g. Source1 performs a form POST with two form items Item1 and Item2 Source2 performs a GET where the data is contained in the query string (?ItemX=2&ItemY=3) Is it possible to have a controller action that will cater for all these cases and perform binding automatically e.g. public ActionResult Test(Dictionary data) { // Do work ... return View(); } Is this possible with a custom binder or some other way? Dont want to work directly with HttpContext.Request if possible

  • ASP.NET MVC: null reference exception using HtmlHelper.TextBox and custom model binder

    - by mr.nicksta
    I have written a class which implements IModelBinder (see below). This class handles a form which has 3 inputs each representing parts of a date value (day, month, year). I have also written a corresponding HtmlHelper extension method to print out three fields on the form. When the day, month, year inputs are given values which can be parsed, but a seperate value fails validation, all is fine - the fields are repopulated and the page served to the user as expected. however when an invalid values are supplied and a DateTime cannot be parsed, i return an arbitrary DateTime so that the fields will be repopulated when returned to the user. I read up on similar problems people have had and they all seemed to be due to lack of calling SetModelValue(). I wasn't doing this, but even after adding the problem has not been resolved. public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { string modelName = bindingContext.ModelName; string monthKey = modelName + ".Month"; string dayKey = modelName + ".Day"; string yearKey = modelName + ".Year"; //get values submitted on form string year = bindingContext.ValueProvider[yearKey].AttemptedValue; string month = bindingContext.ValueProvider[monthKey].AttemptedValue; string day = bindingContext.ValueProvider[dayKey].AttemptedValue; DateTime parsedDate; if (DateTime.TryParse(string.Format(DateFormat, year, month, day), out parsedDate)) return parsedDate; //could not parse date time report error, return current date bindingContext.ModelState.AddModelError(yearKey, ValidationErrorMessages.DateInvalid); //added this after reading similar problems, does not fix! bindingContext.ModelState.SetModelValue(modelName, bindingContext.ValueProvider[modelName]); return DateTime.Today; } the null reference exception is thrown when i attempt to create a textbox for the Year property of the date, but strangely not for Day or Month! Can anyone offer an explanation as to why this is? Thanks :-)

  • asp.net mvc json result format

    - by ile
    public class JsonCategoriesDisplay { public JsonCategoriesDisplay() { } public int CategoryID { set; get; } public string CategoryTitle { set; get; } } public class ArticleCategoryRepository { private DB db = new DB(); public IQueryable<JsonCategoriesDisplay> JsonFindAllCategories() { var result = from c in db.ArticleCategories select new JsonCategoriesDisplay { CategoryID = c.CategoryID, CategoryTitle = c.Title }; return result; } .... } public class ArticleController : Controller { ArticleRepository articleRepository = new ArticleRepository(); ArticleCategoryRepository articleCategoryRepository = new ArticleCategoryRepository(); public string Categories() { var jsonCats = articleCategoryRepository.JsonFindAllCategories().ToList(); //return Json(jsonCats, JsonRequestBehavior.AllowGet); return new JavaScriptSerializer().Serialize(new { jsonCats}); } } This results with following: {"jsonCats":[{"CategoryID":2,"CategoryTitle":"Politika"},{"CategoryID":3,"CategoryTitle":"Informatika"},{"CategoryID":4,"CategoryTitle":"Nova kategorija"},{"CategoryID":5,"CategoryTitle":"Testna kategorija"}]} If I use line that is commented and place JsonResult instead of returning string, I get following result: [{"CategoryID":2,"CategoryTitle":"Politika"},{"CategoryID":3,"CategoryTitle":"Informatika"},{"CategoryID":4,"CategoryTitle":"Nova kategorija"},{"CategoryID":5,"CategoryTitle":"Testna kategorija"}] But, I need result to be formatted like this: {'2':'Politika','3':'Informatika','4':'Nova kateorija','5':'Testna kategorija'} Is there a simple way to accomplish this or I will need to hardcode result? Thanks in advance!

  • Seperation of notification confirmation+storage and handling notification asp.net mvc

    - by bastijn
    After a payment from my web application to a 3rd party the 3rd party sends, next to the direct confirmation message, a notification message. This notification message is stored in my database for future use and I have to send a notification confirmed back. For this purpose I currently use a: return Content("received") Which is standard protocol for the service. Currently, I process the incoming notification by first storing it, than handling it (updating account credits etc in my application) and in the end sending a response. This all works well. But I want to seperate handling the notification and storing+responding to the webservice. The problem is that the "return Content()" is ending my controller method and therefore I cannot simply first send the confirmation message back to the webservice and than call my handle_Notification() method. So the solution would be to replace the return Content() part with something equal which doesn't involve a "return", is this possible, as I do not now the complete URL calling I cannot easily create a simple HTTP POST web request (I tried, might have made an error but did not work). Another solution would be to have some kind of timer or listener which either periodically checks for new notifications in the Database which have to be handled or a listener listening to DB new notifications or something. What is the standard procedure on this, if any?

  • PRG in ASP.NET MVC but with object data transferred to the redirected action

    - by mare
    Following Post-Redirect-Get pattern as described in various spots but maybe in most detail here by Stephen Walter I want to use RedirectToAction but it does not accept a parameter for sending object to it. I can only send route values either as an object or as an RouteValueDictionary. So currently I send object ID and type and pull the object out of the datastore again in the action to which I redirected (like Results). // redirect to confirm view return RedirectToAction("ChangeSuccess", "Redirect", new { slug = tabgroup.Slug, contentType = tabgroup.ContentType }); But I would like to send an object there because I already have it in my updating controller action so I don't need to pull it out again. Is that possible somehow?

  • Spring MVC return ajax response using Jackson

    - by anshumn
    I have a scenario where I am filling a dropdown box in JSP through AJAX response from the server. In the controller, I am retuning a Collection of Product objects and have annotated the return type with @ResponseBody. Controller - @RequestMapping(value="/getServicesForMarket", method = RequestMethod.GET) public @ResponseBody Collection<Product> getServices(@RequestParam(value="marketId", required=true) int marketId) { Collection<Product> products = marketService.getProducts(marketId); return products; } And Product is @Entity @Table(name = "PRODUCT") public class Product implements Serializable { private static final long serialVersionUID = 1L; private int id; private Market market; private Service service; private int price; @Id @GeneratedValue(strategy = GenerationType.AUTO) public int getId() { return id; } public void setId(int id) { this.id = id; } @ManyToOne(fetch=FetchType.LAZY) @JoinColumn(name = "MARKET_ID") public Market getMarket() { return market; } public void setMarket(Market market) { this.market = market; } @ManyToOne(fetch=FetchType.LAZY) @JoinColumn(name = "SERVICE_ID") public Service getService() { return service; } public void setService(Service service) { this.service = service; } @Column(name = "PRICE") public int getPrice() { return price; } public void setPrice(int price) { this.price = price; } } Service is @Entity @Table(name="SERVICE") public class Service implements Serializable { /** * */ private static final long serialVersionUID = 1L; private int id; private String name; private String description; @Id @GeneratedValue @Column(name="ID") public int getId() { return id; } public void setId(int id) { this.id = id; } @Column(name="NAME") public String getName() { return name; } public void setName(String name) { this.name = name; } @Column(name="DESCRIPTION") public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } } In the JSP, I need to get the data from the service field of Product also. So I in my JQuery callback function, I have written like product.service.description to get the data. It seems that by default Jackson is not mapping the associated service object (or any other custom object). Also I am not getting any exception. In the JSP, I do not get the data. It is working fine when I return Collection of some object which does not contain any other custom objects as its fields. Am I missing any settings for this to work? Thanks!

  • MVC 2.0 - JqGrid Sorting with Mulitple Tables

    - by Billy Logan
    I am in the process of implementing the jqGrid and would like to be able to use the sorting functionality. I have run into some issues with sorting columns that are related to the base table. Here is the script to load the grid: public JsonResult GetData(GridSettings grid) { try { using (IWE dataContext = new IWE()) { var query = dataContext.LKTYPE.Include("VWEPICORCATEGORY").AsQueryable(); ////sorting query = query.OrderBy<LKTYPE>(grid.SortColumn, grid.SortOrder); //count var count = query.Count(); //paging var data = query.Skip((grid.PageIndex - 1) * grid.PageSize).Take(grid.PageSize).ToArray(); //converting in grid format var result = new { total = (int)Math.Ceiling((double)count / grid.PageSize), page = grid.PageIndex, records = count, rows = (from host in data select new { TYPE_ID = host.TYPE_ID, TYPE = host.TYPE, CR_ACTIVE = host.CR_ACTIVE, description = host.VWEPICORCATEGORY.description }).ToArray() }; return Json(result, JsonRequestBehavior.AllowGet); } } catch (Exception ex) { //send the error email ExceptionPolicy.HandleException(ex, "Exception Policy"); } //have to return something if there is an issue return Json(""); } As you can see the description field is a part of the related table("VWEPICORCATEGORY") and the order by is targeted at LKTYPE. I am trying to figure out how exactly one goes about sorting that particular field or maybe even a better way to implement this grid using multiple tables and it's sorting functionality. Thanks in advance, Billy

  • MVC and repository pattern data effeciency

    - by Shawn Mclean
    My project is structured as follows: DAL public IQueryable<Post> GetPosts() { var posts = from p in context.Post select p; return posts; } Service public IList<Post> GetPosts() { var posts = repository.GetPosts().ToList(); return posts; } //Returns a list of the latest feeds, restricted by the count. public IList<PostFeed> GetPostFeeds(int latestCount) { List<Post> post - GetPosts(); //CODE TO CREATE FEEDS HERE return feeds; } Lets say the GetPostFeeds(5) is supposed to return the 5 latest feeds. By going up the list, doesn't it pull down every single post from the database from GetPosts(), just to extract 5 from it? If each post is say 5kb from the database, and there is 1 million records. Wont that be 5GB of ram being used per call to GetPostFeeds()? Is this the way it happens? Should I go back to my DAL and write queries that return only what I need?

  • asp mvc unit test HttpContext.Current.Cache?

    - by Paul Creasey
    Here is the first part of my controller code: public class ControlMController : Controller { IControlMService _controlMservice; public IList<User> Users { get { if (System.Web.HttpContext.Current.Cache["users"] == null) { System.Web.HttpContext.Current.Cache["users"] = _controlMservice.GetUsers(); } return (IList<User>)System.Web.HttpContext.Current.Cache["users"]; } } public ControlMController(IControlMService controlMservice) { this._controlMservice = controlMservice; var users = Users; ViewData["Users"] = users; ViewData["jqSelectUsers"] = string.Join(";", users.Select(x => x.UserID + ":" + x.Name).ToArray()); } I'm trying to test it, and because i'm caching using the HttpContext, i'm struggling with null reference exceptions. I've tried using MvcContrib.TestHelper; here is my sample test... [TestMethod] public void EventDetails_Returns_view_with_correct_event() { var builder = new TestControllerBuilder(); var controller = builder.CreateController<ControlMController>( new ControlMService( new MockControlMRepository() )); var view = (controller.EventDetails(1) as ViewResult); Assert.AreEqual(1, (view.ViewData.Model as Event).EventId); } (I haven't quite got round to using DI for my tests! I'm still getting the same null reference exception when the code hits the httpcontext: Error 1 TestCase 'SupportTool.Tests.Services.ControlM.ControlMControllerTests.EventDetails_Returns_view_with_correct_event' failed: System.NullReferenceException: Object reference not set to an instance of an object. at SupportTool.web.Controllers.ControlMController.get_Users() Any ideas?

  • asp.net mvc textbox date format

    - by maxxxee
    My form contains a textbox for date input. When submitted the data is used to add a row to the table. The view is strongly typed to the table. The problem is that the database server is configured with US date format. But the users need to use UK date format in the textbox. When users enter uk date format error is thrown. The database server configuration cannot be changed. So what can be done so that users can enter date in uk format?

  • Custom Membership in ASP.NET MVC 2

    - by Interfector
    Hello, I'm trying to make my Custom Membership starting from ASP.NET's. I have a users table created by me which has as Primary Key a Guid UserId, exactly the sames as ASP.NET's default user and membership table. I have all the Foreign Key relationships built. However, I cannot insert the user into my custom users table. The data gets inserted correctly into the default ASP.NET's tables. I have tried the following scenarios: First version Receive the user model from POST call the CreateUser method of the Membership.class (stuff gets inserted) without modifying the user object, I try to insert it using EF's AddObject I receive the following error: "Cannot insert the value NULL into column 'LoweredUserName', table 'asp.dbo.aspnet_Users'; column does not allow nulls. INSERT fails.\r\nThe statement has been terminated."} System.Exception {System.Data.SqlClient.SqlException The error actually makes sense as EF's AddObject doesn't know how to create the LoweredUserName value, and I don't want to do it, this is ASP.NET's job. Second version Receive the user model from POST call the CreateUser method of the Membership.class (stuff gets inserted) Get the Guid of the freshly inserted system user get the ASP.NET's User object and overwrite that of user.User get the ASP.NET's Membership object and overwrite that of user.Membership (remember the FKs) try again EF's AddObject new error {"The relationship between the two objects cannot be defined because they are attached to different ObjectContext objects."} System.Exception {System.InvalidOperationException} Don't know what this is, but it certenly doesn't make any sense for me. After some googleing I think that it has something to do with the context, but as I'm a beginner I don't know how to fix it. Any ideeas on how to accomplish this task are more than welcomed, especially if they follow some good practices. Thx

  • Encoding problem using Spring MVC

    - by Makis Arvanitis
    Hi all, I have a demo web application that creates users. When I try to insert data in other languages (like french) the characters are not encoded correctly. The code on the controller is: @SuppressWarnings("unchecked") @RequestMapping(value = "/user/create.htm", params={"id"}, method = RequestMethod.GET) public String edit(@RequestParam("id") Long id, ModelMap model) { System.out.println("id is " + id); User user = userService.get(id); model.put("user", user); return "user/create"; } @RequestMapping(value = "/user/create.htm", method = RequestMethod.POST) public String save(@ModelAttribute("user") User user, BindingResult result) { System.out.println(user.getFirstName()); System.out.println(user.getLastName()); validator.validate(user, result); if(result.hasErrors()) { return "user/create"; } userService.save(user); return "redirect:list.htm"; } my web.xml is: ... <filter> <filter-name>encoding-filter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>encoding-filter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> ... and the page is: <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %> <%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> ... <form:form method="post" commandName="user"> ... <form:input path="firstName" cssErrorClass="form-error-field"/> ... when I enter some french characters in the first name then the output from the system.out.println is ????+????? or something similar. I saw other people fixing this with the CharacterEncodingFilter but this doesn't seem to work. Thanks a lot. Edited the filter value.

  • help with jquery ajax and templates in asp.net mvc

    - by NachoF
    So I have a complex form for an IncomeDeclaration. Its going to display a textfield GrossIncome for each Activity that the IncomeDeclaration is related to... this all gets done on the server and works just fine.... the problem is. The User should also be able to add Activities on the fly.. through javascript... so when the user clicks on Add Activity a Dropdown and a textfield must be appended to the bottom the activities list... heres what Ive got so far <tbody id="activities"> @Html.EditorFor(model => model.income.EconomicActivityIncomeDeclarations) </tbody> </table> <a href="#" id="add_activity">Agregar Otra Actividad</a> </fieldset> <script type="text/javascript"> $("#add_activity").click(function () { $.getJSON('/IncomeDeclarations/GetEconomicActivities', function (data) { var select = new Select(); var data = new Array(); for (var i = 0; i < data.length; i++) { var option = new Option(data[i]["name"], data[i]["i"]) //should do something here } //should call the template and append to #activities }); }); </script> <script id="template" type="text/x-jquery-tmpl"> <tr> <td><select name="income.EconomicActivityIncomeDeclarations[${SomeNumber}].EconomicActivityId"> ${MyOptions} </select></td> <td><input type="text" name="income.EconomicActivityIncomeDeclarations[${SomeNumber}].GrossIncome" /></td>> </tr> </script> } The name attribute for both the select and the text_field is key for this to work... otherwise modelbinding wont work... I would think that if the SomeNumber variable is set to new Date.GetTime() model Binding should work just fine... I actually dont see the need of ajax for this but thats another topic.. I just havent figured out a way to do this without ajax... right now I want to get the template to work and append the form elements to the bottom of the list.

  • asp.net mvc log4postsharp

    - by mike
    Hi Iam trying to use log4post sharp for logging purposes, As far as Iam aware I have followed the instructions to get this up and running, I have not installed postsharp, rather I got the library files and midified my cs proj file to target those file, I have also tried installing postsharp on my machine. In either case I end up with this error Error 5 The plug-in "Log4PostSharp" required by the type "Log4PostSharp.LogAttribute" was not found. I have tried googling this and it seems there is no trace of this issue anywhere on the web. One difference between my implementation with other examples is that the postsharp dll that they use is PostSharp.public, mine is just PostSharp. I have tried searching for the former dll but cannot find it anywhere, the download only contains PostSharp.dll. I feel this may be the issue as I have followd all the insturctions to the letter to get this up and running. Any Ideas People?

The way I am trying to do it now is: ViewData["Sex"] = data.Sex; //Set radio button But that is not working. I have tried every possible combination of isChecked properties.

  • ASP.NET MVC ViewModelBuilder Suggestions

    - by Marco
    For anything but trival view models, I use a view model builder that handles the responsibility of generating the view model object. Right now, I use constructor injection of the builders into my controllers but this smells a little since the builder is really dependent upon which action method is being executed. I have two ideas in mind. The first one would involve a custom ActioFilter allowing me to decorate each action method with the appropriate builder to use. The second would be to add an override of the View method that is open to accepting a generic. This is what my code currently looks like. Note, the builder get injected via the ctor. [HttpGet, ImportModelStateFromTempData, Compress] public ActionResult MyAccount() { return View(accountBuilder.Build()); } Here is what option one would look like: [HttpGet, ImportModelStateFromTempData, Compress, ViewModelBuilder(typeof(IMyAccountViewModelBuilder)] public ActionResult MyAccount() { return View(accountBuilder.Build()); } Or option two: [HttpGet, ImportModelStateFromTempData, Compress] public ActionResult MyAccount() { return View<IMyAccountViewModelBuilder>(); } Any thoughts or suggestions would be great!

  • ASP.NET MVC unit test controller with HttpContext

    - by user299592
    I am trying to write a unit test for my one controller to verify if a view was returned properly, but this controller has a basecontroller that accesses the HttpContext.Current.Session. Everytime I create a new instance of my controller is calls the basecontroller constructor and the test fails with a null pointer exception on the HttpContext.Current.Session. Here is the code: public class BaseController : Controller { protected BaseController() { ViewData["UserID"] = HttpContext.Current.Session["UserID"]; } } public class IndexController : BaseController { public ActionResult Index() { return View("Index.aspx"); } } [TestMethod] public void Retrieve_IndexTest() { // Arrange const string expectedViewName = "Index"; IndexController controller = new IndexController(); // Act var result = controller.Index() as ViewResult; // Assert Assert.IsNotNull(result, "Should have returned a ViewResult"); Assert.AreEqual(expectedViewName, result.ViewName, "View name should have been {0}", expectedViewName); } Any ideas on how to mock the Session that is accessed in the base controller so the test in the descendant controller will run?

  • ASP MVC 2: Error with dropdownlist on POST

    - by wh0emPah
    Okay i'm new to asp mvc2 and i'm experiencing some problems with the htmlhelper called Html.dropdownlistfor(); I want to present the user a list of days in the week. And i want the selected item to be bound to my model. I have created this little class to generate a list of days + a short notation which i will use to store it in the database. public static class days { public static List<Day> getDayList() { List<Day> daylist = new List<Day>(); daylist.Add(new Day("Monday", "MO")); daylist.Add(new Day("Tuesday", "TU")); // I left the other days out return daylist; } public class Dag{ public string DayName{ get; set; } public string DayShortName { get; set; } public Dag(string name, string shortname) { this.DayName= name; this.DayShortName = shortname; } } } I really have now idea if this is the correct way to do it Then i putted this in my controller: SelectList _list = new SelectList(Days.getDayList(), "DayShortName", "DayName"); ViewData["days"] = _list; return View(""); I have this line in my model public string ChosenDay { get; set; } And this in my view to display the list: <div class="editor-field"> <%: Html.DropDownListFor(model => model.ChosenDay, ViewData["days"] as SelectList, "--choose Day--")%> </div> Now this all works perfect. On the first visit, But then when i'm doing a [HttpPost] Which looks like the following: [HttpPost] public ActionResult Registreer(EventRegistreerViewModel model) { // I removed some unrelated code here // The code below executes when modelstate.isvalid == false SelectList _list = new SelectList(Days.getDayList(), "DayShortName", "DayName"); ViewData["days"] = _list; return View(model); } Then i will have the following exception thrown: The ViewData item that has the key 'ChosenDay' is of type 'System.String' but must be of type 'IEnumerable<SelectListItem>'. This errors gets thrown at the line in my view where i display the dropdown list. I really have no idea how to solve this and tried several solutions i found online. but none of them really worked. Ty in advance!

  • Can't get past "A potentially dangerous Request.Form value was detected..." error

    - by joshb
    I'm doing my first ASP.NET MVC2 project and I can't get past the "A potentially dangerous Request.Form value was detected..." error when trying to submit a form. I've done this in MVC1 using the ValidateInputAttribute and I've read about the breaking change in .NET 4 that requires setting the request validation mode in the web.config. Basically I'm doing exactly what is outlined in this thread: http://stackoverflow.com/questions/2019843/a-potentially-dangerous-request-form-value-in-mvc-2-asp-net-4-0. Nothing's working though so I must be missing something. Here's my code: Web.config <configuration> <system.web> <httpHandlers> <add path="*" verb="*" type="System.Web.HttpNotFoundHandler"/> </httpHandlers> <httpRuntime requestValidationMode="2.0" /> <pages validateRequest="true" pageParserFilterType="System.Web.Mvc.ViewTypeParserFilter, System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" pageBaseType="System.Web.Mvc.ViewPage, System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" userControlBaseType="System.Web.Mvc.ViewUserControl, System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"> <controls> <add assembly="System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" namespace="System.Web.Mvc" tagPrefix="mvc" /> </controls> </pages> </system.web> <system.webServer> <validation validateIntegratedModeConfiguration="false" /> <handlers> <remove name="BlockViewHandler"/> <add name="BlockViewHandler" path="*" verb="*" preCondition="integratedMode" type="System.Web.HttpNotFoundHandler" /> </handlers> </system.webServer> </configuration> Controller action [AcceptVerbs(HttpVerbs.Post)] [ValidateInput(false)] public ActionResult Edit(Page pageToEdit) { // do stuff.... } Any ideas on what I'm doing wrong here?

    Hi, I have an Employee object which has an image property. Image class contains image metadata as image caption, and image file name. If I upload a new image for an employee on async way without full post back the new image is not appeared on the page. I use GUID to name the image file to avoid the page caching. I do the image modifying the following way: ctrEmployee employee = Repository.Get(PassedItemID); if (employee.ctrImage != null) { string fullFileName = serverFolder + employee.ctrImage.FileName; FileInfo TheFile = new FileInfo(fullFileName); if (TheFile.Exists) { TheFile.Delete(); } fileName = Guid.NewGuid() + ".jpg"; employee.ctrImage.FileName = fileName; } resizedBmp.Save(string.Format("{0}{1}", serverFolder, fileName), System.Drawing.Imaging.ImageFormat.Jpeg); Repository.Edit<ctrEmployee>(employee); ImageID = employee.Image.Value; return PartialView(UserControlPaths.Thumbnail, new ThumbnailDataModel(employee.Image.Value, 150, 150)); The partial view has an image tag which gets the saved image url string which is a GUID. Anybody has an idea what I do wrong?
