  • Set cookie value before view loaded in MVC?

    - by James123
    I need to set a cookie value before my view called. otherwise I have to refresh the page to get cookie value in the view. The problem here is the value of cookie will get in controller. [HttpGet] [Route("Abstract/{meetingCode}")] [AllowAnonymous] public ActionResult Index(string meetingCode) { var meetingAbstract = new MeetingAbstract(); meetingAbstract.Meeting = _abstractContext.GetMeetingWithMeetingCode(meetingCode); if (meetingAbstract.Meeting != null) { var cookie = new HttpCookie("_culture"); cookie.Value = meetingAbstract.Meeting.language.language_locale_code;//"en-US"; cookie.Expires = DateTime.Now.AddDays(365); cookie.Path = "/"; this.ControllerContext.HttpContext.Response.Cookies.Add(cookie); ... Any other way without refresh the page again to set cookie value?

  • ASP.NET MVC2 - Trim white space from form submits before server-side validation?

    - by David Lively
    If I add a validation attribute: public class ProductDownloadListModel { //xxxxx-xxxxx-xxxxx [Required] [StringLength(17)] public string PSN { get; set; } public DateTime PsnExpirationDate { get; set; } public DataTable Downloads { get; set; } } and the user enters a 17-character string but includes white space on the end, I get a validation error because the string is greater than that specified by the [StringLength(17)] attribute. How can I prevent this? I'd prefer not to have to have javaScript trim the string before submits.

  • Routing optional parameters with dashes in MVC

    - by Géza
    I've made an routing definition like this: routes.MapRoute("ProductSearch", "Search-{MainGroup}-{SubGroup}-{ItemType}", new { controller = "Product", action = "Search", MainGroup = "", SubGroup = "", ItemWebType = ""}); It is not working if the parameters are empty. Actually it resolves the url, so Url.Action method resolves the path "Search-12--" but the link is not working, so the GET of the page is not working With slashes it is working the Url.Action method makes "Search/12" "Search/{MainGroup}/{SubGroup}/{ItemType}" is it somehow possible to correct it?

  • ASP.NET MVC 2 model properties binding order

    - by bniwredyc
    Is there a way to change order in which the default binder binds property values of model? For example I have model class A: class A { public string A1 {get; set;} public string A2 {get; set;} } and action DoSomethig: public ActionResult DoSomething(A model) { ... } I want that A2 property has been bound before the A1 property. Is it possible? Or I need to write custom binder?

  • How do I clear MVC client side validation errors when a cancel button is clicked when a user has inv

    - by Sci-fi
    I have a partial view that is rendered within a main view. The partial view takes advantage of System.ComponentModel.DataAnnotations and Html.EnableClientValidation(). A link is clicked, and div containing the partial view is displayed within a JQuery.Dialog(). I then click the save button without entering any text in my validated input field. This causes the client side validation to fire as expected, and display the '*required' message beside the invalid field. When the cancel button is clicked, I want to reset the client side MVC validation back to it's default state and remove any messages, ready for when the user opens the dialog again. Is there a recommended way of doing this?

  • SharePoint Apps and Windows Azure

    - by ScottGu
    Last Monday I had an opportunity to present as part of the keynote of this year’s SharePoint Conference.  My segment of the keynote covered the new SharePoint Cloud App Model we are introducing as part of the upcoming SharePoint 2013 and Office 365 releases.  This new app model for SharePoint is additive to the full trust solutions developers write today, and is built around three core tenants: Simplifying the development model and making it consistent between the on-premises version of SharePoint and SharePoint Online provided with Office 365. Making the execution model loosely coupled – and enabling developers to build apps and write code that can run outside of the core SharePoint service. This makes it easy to deploy SharePoint apps using Windows Azure, and avoid having to worry about breaking SharePoint and the apps within it when something is upgraded.  This new loosely coupled model also enables developers to write SharePoint applications that can leverage the full capabilities of the .NET Framework – including ASP.NET Web Forms 4.5, ASP.NET MVC 4, ASP.NET Web API, EF 5, Async, and more. Implementing this loosely coupled model using standard web protocols – like OAuth, JSON, and REST APIs – that enable developers to re-use skills and tools, and easily integrate SharePoint with Web and Mobile application architectures. A video of my talk + demos is now available to watch online: In the talk I walked through building an app from scratch – it showed off how easy it is to build solutions using new SharePoint application, and highlighted a web + workflow + mobile scenario that integrates SharePoint with code hosted on Windows Azure (all built using Visual Studio 2012 and ASP.NET 4.5 – including MVC and Web API). The new SharePoint Cloud App Model is something that I think is pretty exciting, and it is going to make it a lot easier to build SharePoint apps using the full power of both Windows Azure and the .NET Framework.  Using Windows Azure to easily extend SaaS based solutions like Office 365 is also a really natural fit and one that is going to offer a bunch of great developer opportunities.  Hope this helps, Scott  P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • Invoke WCF rest service razor mvc 4

    - by Raj Esh
    I have been using jQuery to access my REST based wcf service which does not export the meta information. Using ajax, i could populate data into controls. I need guidance and directions as to how i can use these Rest service in my controller. I can't add Service reference to my MVC 4 project since my WCF rest does not to expose Metadata. Should i use UNITY? or any other DI frameworks?. Any sample would be of great help.

  • Aplicações do SharePoint e Windows Azure

    - by Leniel Macaferi
    Segunda-feira passada eu tive a oportunidade de me apresentar dando uma palestra na SharePoint Conference (em Inglês). Meu segmento na palestra cobriu o novo modelo de Aplicações para Nuvem do SharePoint (SharePoint Cloud App Model) que estamos introduzindo como parte dos próximos lançamentos do SharePoint 2013 e Office 365. Este novo modelo de aplicações para o SharePoint é aditivo para as soluções de total confiança que os desenvolvedores escrevem atualmente, e é construído em torno de três pilares principais: Simplificar o modelo de desenvolvimento tornando-o consistente entre a versão local do SharePoint e a versão online do SharePoint fornecida com o Office 365. Tornar o modelo de execução flexível - permitindo que os desenvolvedores criem aplicações e escrevam código que pode ser executado fora do núcleo do serviço do SharePoint. Isto torna mais fácil implantar aplicações SharePoint usando a Windows Azure, evitando a preocupação com a quebra do SharePoint e das aplicações que rodam dentro dele quando algo é atualizado. Este novo modelo flexível também permite que os desenvolvedores escrevam aplicações do SharePoint que podem alavancar as capacidades do .NET Framework - incluindo ASP.NET Web Forms 4.5, ASP.NET MVC 4, ASP.NET Web API, Entity Framework 5, Async, e mais. Implementar este modelo flexível utilizando protocolos padrão da web - como OAuth, JSON e APIs REST - que permitem aos desenvolvedores reutilizar habilidades e ferramentas, facilmente integrando o SharePoint com arquiteturas Web e arquiteturas para aplicações móveis. Um vídeo da minha palestra + demos está disponível para assistir on-line (em Inglês): Na palestra eu mostrei como construir uma aplicação a partir do zero - ela mostrou como é fácil construir soluções usando a nova aplicação SharePoint, e destacou um cenário web + workflow + móvel que integra o SharePoint com código hospedado na Windows Azure (totalmente construído usando o Visual Studio 2012 e ASP.NET 4.5 - incluindo MVC e Web API). O novo Modelo de Aplicações para Nuvem do SharePoint é algo que eu acho extremamente emocionante, e que vai tornar muito mais fácil criar aplicações SharePoint usando todo o poder da Windows Azure e do .NET Framework. Usar a Windows Azure para estender facilmente soluções baseadas em SaaS como o Office 365 é também algo muito natural e que vai oferecer um monte de ótimas oportunidades para os desenvolvedores.  Espero que ajude, - Scott P.S. Além do blog, eu também estou utilizando o Twitter para atualizações rápidas e para compartilhar links. Siga-me em: twitter.com/ScottGu Texto traduzido do post original por Leniel Macaferi.

  • Implementing separation of concerns via MVC

    - by user2368481
    I'm creating a question to see if my understanding of MVC separation is correct, I haven't been able to find a clear answer anywhere online. So is this the right way to implement it (in Java): I would have 3 .java files, one each for Model, Controller, View. I would put all the classes related to Model in the Model.java like so: //Model.java { public class Model //class fields public Model(); public ModelClassA(); public ModelClassB(); public ModelClassC(); } With the ModelClasses being any class that I consider belonging to the Model. Is it correct to have the classes within the Model Class, as I have read that nested classes should be avoided where possible.

  • Is the 'C' in MVC really necessary?

    - by Anne Nonimus
    I understand the role of the model and view in the Model-View-Controller pattern, but I have a hard time understanding why a controller is necessary. Let's assume we're creating a chess program using an MVC approach; the game state should be the model, and the GUI should be the view. What exactly is the controller in this case? Is it just a separate class that has all the functions that will be called when you, say, click on a tile? Why not just perform all the logic on the model in the view itself?

  • Concerns on first ASP.NET cloud application

    - by RPK
    I am writing a small ASP.NET Web Application. My worries are that I want to keep the architecture same giving me the option to install it on an Intranet or on a Cloud Platform. I am not using MVC but lately learned that Azure only supports ASP.NET MVC applications. I want to know whether ASP.NET Web Forms application work on Azure/AppHarbor or not. Do I need to convert this application to MVC if Web Forms is not supported? Will the same application run on Intranet as well?

  • Flash messages in ASP.NET MVC without sessions

    - by Fernando Correia
    I'm developing a web application for Windows Azure using ASP.NET MVC 4. I would like to enforce one restriction in the architecture: do not use Session. To achieve availability on Azure, and since there is no sticky sessions, I would need to store the session data in some central service, probably either SQL Azure or the Caching Service. I would rather avoid sessions on the SQL database to avoid the increased latency, and the caching service on Azure is very expensive for the ammount of memory offered. On the other hand, I would like to have the ability to easily pass Flash-style messages among redirects. TempData is the recommended way to do this, but by default it uses the session object. So I would like to know: Is there an alternative way to use TempData that doesn't require sessions or shared data between servers? Cookies perhaps? Is there a better alternative I'm overlooking?

  • Best open source ASP.NET MVC e-commerce projects

    - by Øyvind Knobloch-Bråthen
    I need to get a e-commerce site up and running, but I really don't want to program it from the bottom up if I don't need to. I want to program it using ASP.NET MVC. I'm looking for a good open source alternative (or one for purchase if it's modular enough) that I can use as a base and enhance with the needed functions? It has to have all "normal" e-commerce functions, and also the possibility to integrate with a credit card API of my choice. If anyone have any recommendations for me here, I would appreciate it :)

  • MVC shared model different required fields on different type

    - by kurasa
    I have a model called Car and depending on what type of Car the user select the view is presented differently. For example the user selects from a grid of different cars and depending if it is a Volvo or a Kia or a Ford the view must allow different fields to be editable. For example with a Volvo the color is editable and is mandatory but with a Kia it is not. I would like to use the one Car class to bind the view but want the client side validation to pick up the required fields based on what type of car. I want to go only to one Action method for the Update what is a good way to approach this problem...? create a base class and inherit from it? will this give me binding problems..?

  • Is it practical to have perfect validation score on HTML?

    - by Truth
    I was in a heated discussion the other day, about whether or not it's practical to have a perfect validation score on any HTML document. By practical I mean: Does not take a ridiculous amount of time compared to it's almost-perfect counterpart. Can be made to look good on older browsers and to be usable on very old browsers. Justifies the effort it may take to do so (does it come with some kind of reward on SEO/Usability/Accessibility that cannot be achieved in a simpler way with almost-perfect validation) So basically, is perfect validation score practical on any HTML document?

  • MVC Design Pattern to Combine Multiple Models for use

    - by roverred
    In my design, I have multiple models and each model has a controller. I need to use all the models to process some operation. Most examples I see are pretty simple with 1 view, 1 controller, and 1 model. How would you get all these models together? Only ways I can think of are 1) Have a top-level controller which has a reference to every controller. Those controllers will have a getter/setter function for their model. Does this violate MVC because every controller should have a model? 2) Have an Intermediate class to combine every model into a one model. Then you create a controller for that new super model. Do you know of any better ideas? Thanks.

  • Combining two MVC frameworks in a project

    - by SASM
    Is it any good to combine two MVC frameworks together in a project? Is it a fairly common approach? I am thinking about using a serverside framework like CodeIgniter/Laravel and client side framework AngularJS in a predominantly CRUD based web project. I am a bit apprehensive about this idea. I think this approach does not get the best out of both frameworks and can kind of get in way of each other making the application needlessly complicated. Are there some good approaches/practices if one wants to combine these frameworks together?

  • Search and Replace in MVC

    - by danip
    What would be a good MVC/OOP/GRASP/SOLID structure for a search/replace functionality. Methods: search/searchNext/replace/replaceAll. I'm interested only in the PHP arhitecture and how a professional developer would implement this in it's OWN FRAMEWORK. What names would you use for the classes? What subfolders would you used in your MODEL folder? How would you connect the MODELS/CONTROLLER? This is just a arhitecture question to understand better the principles of good OOP in practice. My current implementation is very simplistic using a service model: /controller/SearchReplaceController.php /models/services/SearchReplaceService.php The problem with this is I know I'm breaking SRP in the service but I found this somehow acceptable. Also creating a service does not feel like the best solution for this.

  • Populating FullCalendar events from MVC

  • Problem binding action parameters using FCKeditor, AJAX and ASP.NET MVC

    - by TonE
    I have a simple ASP.Net MVC View which contains an FCKeditor text box (created using FCKeditor's Javascript ReplaceTextArea() function). These are included within an Ajax.BeginForm helper: <% using (Ajax.BeginForm("AddText", "Letters", new AjaxOptions() { UpdateTargetId = "addTextResult" })) {%> <div> <input type="submit" value="Save" /> </div> <div> <%=Html.TextArea("testBox", "Content", new { @name = "testBox" })%> <script type=""text/javascript""> window.onload = function() { var oFCKeditor = new FCKeditor('testBox') ; var sBasePath = '<%= Url.Content("~/Content/FCKeditor/") %>'; oFCKeditor.BasePath = sBasePath; oFCKeditor.ToolbarSet = "Basic"; oFCKeditor.Height = 400; oFCKeditor.ReplaceTextarea() ; } </script> <div id="addTextResult"> </div> <%} %> The controller action hanlding this is: [ValidateInput(false)] public ActionResult AddText(string testBox) { return Content(testBox); } Upon initial submission of the Ajax Form the testBox string in the AddText action is always "Content", whatever the contents of the FCKeditor have been changed to. If the Ajax form is submitted again a second time (without further changes) the testBox paramater correctly contains the actual contents of the FCKeditor. If I use a Html.TextArea without replacing with FCKeditor it works correctly, and if I use a standard Post form submit inplace of AJAX all works as expected. Am I doing something wrong? If not is there a suitable/straight-forward workaround for this problem?

  • ASP.NET MVC pagination problem????

    - by MD_Oppenheimer
    OK, This is starting to get mildly irritating. I tried to implement Twitter style paging using ASP.NET MVC and JQuery my problem is that when not using Request.IsAjaxRequest() (for users with javascript turned off) it works fine, obviously posting back the whole page. when I run the code for Request.IsAjaxRequest(), it skips entries, and does not return result in order. this is the code I have: public ActionResult Index(int? startRow) { StatusUpdatesRepository statusUpdatesRepository = new StatusUpdatesRepository(); if (!startRow.HasValue) startRow = Globals.Settings.StatusUpdatesSection.StatusUpdateCount;//5 Default starting row //Retrieve the first page with a page size of entryCount int totalItems; if (Request.IsAjaxRequest()) { IEnumerable<StatusUpdate> PagedEntries = statusUpdatesRepository.GetLastStatusUpdates(startRow.Value,Globals.Settings.StatusUpdatesSection.StatusUpdateCount, out totalItems); if (startRow < totalItems) AddMoreUrlToViewData(startRow.Value); return View("StatusUpdates", PagedEntries); } //Retrieve the first page with a page size of global setting // First run skip 0 take 5 IEnumerable<StatusUpdate> entries = statusUpdatesRepository.GetLastStatusUpdates(0,startRow.Value, out totalItems); if (startRow < totalItems) AddMoreUrlToViewData(startRow.Value); return View(entries); } private void AddMoreUrlToViewData(int entryCount) { ViewData["moreUrl"] = Url.Action("Index", "Home", new { startRow = entryCount + Globals.Settings.StatusUpdatesSection.StatusUpdateCount }); } My GetLastStatusUpdates function: public IQueryable GetLastStatusUpdates(int startRowIndex, int maximumRows,out int statusUpdatesCount ) { statusUpdatesCount = db.StatusUpdates.Count(); return db.StatusUpdates .Skip(startRowIndex) .Take(maximumRows) .OrderByDescending(s = s.AddedDate); } Really fresh out out of ideas as to why this is not working properly when responding to a Request.IsAjaxRequest(), ie when I turn of javascript in the browser, the code works perfectly, except I don't want to repost the whole page????
