  - by Inge Henriksen

  I want to do some processing on a attribute before returning the view. If I set the appModel.Markup returned in the HttpPost ActionResult method below to "modified" it still says "original" on the form. Why cant I modify my attribute in a HttpGet ActionResult method? [HttpGet] public ActionResult Index() { return View(new MyModel { Markup = "original" }); } [HttpPost] public ActionResult Index(MyModel appModel) { return View(new MyModel { Markup = "modified" }); }

• Asp.net: Replace GenericPrincipal

  - by Pickels

  Hello, I was wondering what the best way is to replace the genericPrincipal with my own CustomGenericPrincipal. At the moment I have something like this but I aint sure if it's correct. protected void Application_AuthenticateRequest(Object sender, EventArgs e) { HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName]; if (authCookie != null) { FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value); var identity = new CustomIdentity(authTicket); var principal = new CustomPrincipal(identity); Context.User = principal; } else { //Todo: check if this is correct var genericIdentity = new CustomGenericIdentity(); Context.User = new CustomPrincipal(genericIdentity); } } I need to replace it because I need a Principal that implements my ICustomPrincipal interface because I am doing the following with Ninject: Bind<ICustomPrincipal>().ToMethod(x => (ICustomPrincipal)HttpContext.Current.User) .InRequestScope(); So what's the best way to replace the GenericPrincipal? Thanks in advance, Pickels

• Calling ASP.NET MVC Controller explicitly via AJAX

  - by effkay

  I know that I can use following piece of code to refresh a div: <%=Ajax.ActionLink( "Update", "Administration", new AjaxOptions { UpdateTargetId = "grid", LoadingElementId = "grid-wait" } ) %> But this creates a link; user will have to click on it to get the view refreshed. How can I make it automatic, i.e., like say if I want the grid to be refreshed after every five seconds?

• Site Security/Access management for asp.net mvc application

  - by minal

  I am trying to find a good pattern to use for user access validation. Basically on a webforms application I had a framework which used user roles to define access, ie, users were assigned into roles, and "pages" were granted access to a page. I had a table in the database with all the pages listed in it. Pages could have child pages that got their access inherited from the parent. When defining access, I assigned the roles access to the pages. Users in the role then had access to the pages. It is fairly simple to manage as well. The way I implemented this was on a base class that every page inherited. On pageload/init I would check the page url and validate access and act appropriately. However I am now working on a MVC application and need to implement something similar, however I can't find a good way to make my previous solution work. Purely because I don't have static pages as url paths. Also I am not sure how best to approach this as I now have controllers rather then aspx pages. I have looked at the MVCSitemapprovider, but that does not work off a database, it needs a sitemap file. I need control of changing user persmissions on the fly. Any thoughts/suggestions/pointers would be greatly appreciated.

• Validation firing in ASP.NET MVC

  - by rkrauter

  I am lost on this MVC project I am working on. I also read Brad Wilsons article. http://bradwilson.typepad.com/blog/2010/01/input-validation-vs-model-validation-in-aspnet-mvc.html I have this: public class Employee { [Required] public int ID { get; set; } [Required] public string FirstName { get; set; } [Required] public string LastName { get; set; } } and these in a controller: public ActionResult Edit(int id) { var emp = GetEmployee(); return View(emp); } [HttpPost] public ActionResult Edit(int id, Employee empBack) { var emp = GetEmployee(); if (TryUpdateModel(emp,new string[] { "LastName"})) { Response.Write("success"); } return View(emp); } public Employee GetEmployee() { return new Employee { FirstName = "Tom", LastName = "Jim", ID = 3 }; } and my view has the following: <% using (Html.BeginForm()) {%> <%= Html.ValidationSummary() %> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%= Html.LabelFor(model => model.FirstName) %> </div> <div class="editor-field"> <%= Html.DisplayFor(model => model.FirstName) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.LastName) %> </div> <div class="editor-field"> <%= Html.TextBoxOrLabelFor(model => model.LastName, true)%> <%= Html.ValidationMessageFor(model => model.LastName) %> </div> <p> <input type="submit" value="Save" /> </p> </fieldset> <% } %> Note that the only field editable is the LastName. When I postback, I get back the original employee and try to update it with only the LastName property. But but I see on the page is the following error: •The FirstName field is required. This from what I understand, is because the TryUpdateModel failed. But why? I told it to update only the LastName property. I am using MVC2 RTM Thanks in advance.

• Ajax comments form in ASP.NET MVC2, howto?

  - by Artiom Chilaru

  I've been playing around with different aspects of MVC for some time now, and I've reached a situation where I'm not sure what would be the best way to solve a problem. I'm hoping that the SO community will help me out here :P I've seen a number of examples of Ajax.BeginForm on the internet, and it seems like a very nifty idea. E.g. you have a dropdown where you select a customer - and on selecting one it will load this client's details in some placeholder on the page. This works perfectly fine. But what to do if you want to tie in some validation in the box? Just hypothetically, imagine an article page, and user comments in the bottom. Below the comments area there's an ajax-y "Add comment" box. When a user adds a comment, it will appear in the comments area, below the last comment there. If I set the Ajax.BeginForm to Append the result of the call to the Comments area, it will work fine. But what if the data posted is not valid? Instead of appending a "successful" comment to the comments area I have to show the user validation errors. At this point I decided that the area INSIDE the Ajax.BeginForm will be inside a partial, and the form's submits will return this partial. Validation works fine. On each submit we reload the contents inside the form element. But how to add the successful comment to the top? Other things to consider: The comment form also has a "Preview" button. When the user clicks on Preview, I should load the rendered comment into a preview box. This will probably be inside the form area as well. I was thinking of using Json results instead. When the user submits the form, the server code will generate a Json object with a Success value, and html rendered partials as some properties. Something like { "success": true, "form": "<html form data>", "comment": "successful comment html to inject into the page" } This would be a perfect solution, except there's no way in MVC to render a partial into a string, inside the controller (separation of context, remember?). So.. what should I do then? Any "correct" way to implement this? Anyone???

• Correct way to perform an update using ADO.Net Entity Model in .net 4

  - by sf

  Hi, I just wanted to clarify if this is the appropriate way to perform an update using a designer generated ADO.NET Entity Model. I was wondering if there was a way to perform an update without creating the sqlMenu object. public class MenusRepository { public void UpdateMenu(Menu menu) { // _context is instantiated in constructor Menu sqlMenu = (from m in _context.Menus where m.MenuId == menu.MenuId select m).FirstOrDefault(); if (sqlMenu == null) throw new ArgumentException("Can't update a Menu which does not exist"); // associate values here sqlMenu.Name = menu.Name; _context.SaveChanges(); } }

• Fetching custom Authorization header from incoming PHP request

  - by jpatokal

  So I'm trying to parse an incoming request in PHP which has the following header set: Authorization: Custom Username Simple question: how on earth do I get my hands on it? If it was Authorization: Basic, I could get the username from $_SERVER["PHP_AUTH_USER"]. If it was X-Custom-Authorization: Username, I could get the username from $_SERVER["HTTP_X_CUSTOM_AUTHORIZATION"]. But neither of these are set by a custom Authorization, var_dump($_SERVER) reveals no mention of the header (in particular, AUTH_TYPE is missing), and PHP5 functions like get_headers() only work on responses to outgoing requests. I'm running PHP 5 on Apache with an out-of-the box Ubuntu install.

• Can I develop for .NET Framework 4 in Visual Studio 2008?

  - by Zack Peterson

  My ASP.NET application runs in IIS on my web server and uses Microsoft .NET Framework 4 Beta 2. (Its Application Pool is set to .NET Framework version .NET Framework v4.0.21006.) It gives this new error: A potentially dangerous Request.Form value was detected from the client... This is due to a breaking change in .NET 4. To revert to the behavior of the ASP.NET 2.0 request validation feature, I added the following setting in the Web.config file: <httpRuntime requestValidationMode="2.0" /> Now Visual Studio 2008 throws a compile-time error: The 'requestValidationMode' attribute is not declared. And I can no longer debug on my development machine using the ASP.NET Development Server that comes with Visual Studio. I need Visual Studio and its ASP.NET Development Server to recognize the new .NET Framework 4 requestValidationMode attribute. How can I debug my application in .NET 4? Must I switch from Visual Studio 2008 to Visual Studio 2010 Beta 2?

• ASP MVC.Net 3 RC2 bug ?

  - by Jarek Waliszko

  Hello, so far I've been using ASP.Net 3 BETA. Everything was working fine till the update to RC2 version. Of course I've read ScottGu's article about RC2. My problem is following. Basically I have 2 controllers: public class DynamicPageController : Controller { public ActionResult Redirect(string resource, int? pageNumber, int? id) { } } public class SystemController : Controller { public ActionResult Index() { } } In the Globals.asax I have routes like this: public static void RegisterRoutes(RouteCollection routes) { routes.MapRoute( "SystemRoute", "System/{action}", new { controller = "System", action = "Index" } ); routes.MapRoute( "PageRoute", "{resource}/{id}/{pageNumber}", new { controller = "DynamicPage", action = "Redirect", resource = UrlParameter.Optional, pageNumber = UrlParameter.Optional, id = UrlParameter.Optional } ); } In the code, I have simple link creation: System.Web.Mvc.UrlHelper u = new System.Web.Mvc.UrlHelper(context); string url = u.Action("Index", "System"); and the url is "/my_app/System" in both versions (BETA and RC2) But the code below (the syntax is the same as above, only controller and action names are different): string url = u.Action("Redirect", "DynamicPage", new RouteValueDictionary(new { resource = "Home" })); gives url which is null in RC2. It should be (and in fact in BETA was) "/my_app/Home" Why ? Is it a bug ? How can I create url for my "DynamicPage" controller ? Regards BTW: From where can I now download ASP.Mvc BETA version along with ASP.Net Web Pages 1.0 installers ? Since RC2 announcement I have problems finding mentioned 2 installers. Normally I would upgrade my code but this issue described above makes me stay with BETA for a while, since I have no time for migration and testing everything now.

I structured the solution in 4 projects: POCO entities Domain model Services web application When the application performs a query on the database, use one of the services provided, the service uses the repository and the small classes, as a result I have some dynamic proxy objects that I would like to convert in my domain entities, before using them in mvc views, but I do not know how. Dovrebber be set as the translator? This approach is reasonable?

• RavenDB Ids and ASP.NET MVC3 Routes

  - by goober

  Hey all, Just building a quick, simple site with MVC 3 RC2 and RavenDB to test some things out. I've been able to make a bunch of projects, but I'm curious as to how Html.ActionLink() handles a raven DB ID. My example: I have a Document called "reasons" (a reason for something, just text mostly), which has reason text and a list of links. I can add, remove, and do everything else fine via my repository. Below is the part of my razor view that lists each reason in a bulleted list, with an Edit link as the first text: @foreach(var Reason in ViewBag.ReasonsList) { <li>@Html.ActionLink("Edit", "Reasons", "Edit", new { id = Reason.Id }, null) @Reason.ReasonText</li> <ul> @foreach (var reasonlink in Reason.ReasonLinks) { <li><a href="@reasonlink.URL">@reasonlink.URL</a></li> } </ul> } The Problem This works fine, except for the edit link. While the values and code here appear to work directly (i.e the link is firing directly), RavenDB saves my document's ID as "reasons/1". So, when the URL happens and it passes the ID, the resulting route is "http://localhost:4976/Reasons/Edit/reasons/2". So, the ID is appended correctly, but MVC is interpreting it as its own route. Any suggestions on how I might be able to get around this? Do I need to create a special route to handle it or is there something else I can do?
