  • Why do i need PUT or DELETE Http Verbs ?

    - by Barbaros Alp
    After the release of MVC 2, i have started to check and play with the new features. But i couldnt understand that why do i need to use PUT or DELETE verbs ? I have searched about it and read some articles but i couldnt get it. What is the main purpose of DELETE and PUT (and do they have any advantages rather than using a GET or POST method) even though i can handle all of the requests with GET and POST...

  • .NET MVC: How to use .NET controls with MVC?

    - by aximili
    I am very new to MVC. I've been learning to use plain HTML or HtmlHelpers, eg. for textbox, and get the value back in the Controller using Request.Form. But how do I use .NET controls with MVC? (eg. FileUpload) (The reason I ask is I am trying to use a custom control for uploading multiple files - it's Flajaxian File Uploader, if anyone knows about it. It works with webforms, but I have no idea how this thing is gonna work with MVC.) Thanks in advance

  • Architecture with NHibernate and Repositories

    - by Matthew
    I've been reading up on MVC 2 and the recommended patterns, so far I've come to the conclusion (amongst much hair pulling and total confusion) that: Model - Is just a basic data container Repository - Provides data access Service - Provides business logic and acts as an API to the Controller The Controller talks to the Service, the Service talks to the Repository and Model. So for example, if I wanted to display a blog post page with its comments, I might do: post = PostService.Get(id); comments = PostService.GetComments(post); Or, would I do: post = PostService.Get(id); comments = post.Comments; If so, where is this being set, from the repository? the problem there being its not lazy loaded.. that's not a huge problem but then say I wanted to list 10 posts with the first 2 comments for each, id have to load the posts then loop and load the comments which becomes messy. All of the example's use "InMemory" repository's for testing and say that including db stuff would be out of scope. But this leaves me with many blanks, so for a start can anyone comment on the above?

  • How come module-level validation errors only display when property-level validators are Valid?

    - by jonathanconway
    I'm using the module-level validator: 'PropertiesMustMatch' on my view-model, like so: [PropertiesMustMatch("Password", "PasswordConfirm")] public class HomeIndex { [Required] public string Name { get; set; } public string Password { get; set; } public string PasswordConfirm { get; set; } } I'm noticing that if I submit the form without Name filled in, the ValidationSummary() helper returns only the following error: The Name field is required. However, if I fill in Name, then ValidationSummary() will return a PropertiesMustMatch error: 'Password' and 'PasswordConfirm' do not match. So it looks like the property-level validators are being evaluated first, then the model-level validators. I would much prefer if they were all validated at once, and ValidationSummary would return: The Name field is required. 'Password' and 'PasswordConfirm' do not match. Any ideas what I can do to fix this? I'm studying the MVC 2 source-code to try to determine why this happens.

  • Ninject with MembershipProvider | RoleProvider

    - by DVark
    I'm using ninject as my IoC and I wrote a role provider as follows: public class BasicRoleProvider : RoleProvider { private IAuthenticationService authenticationService; public BasicRoleProvider(IAuthenticationService authenticationService) { if (authenticationService == null) throw new ArgumentNullException("authenticationService"); this.authenticationService = authenticationService; } /* Other methods here */ } I read that Provider classes get instantiated before ninject gets to inject the instance. How do I go around this? I currently have this ninject code: Bind<RoleProvider>().To<BasicRoleProvider>().InRequestScope(); From this answer here. If you mark your dependencies with [Inject] for your properties in your provider class, you can call kernel.Inject(MemberShip.Provider) - this will assign all dependencies to your properties. I do not understand this.

  • I can't get datepicker to work

    - by vikitor
    Hi, I need a field that displays the datepicker. I followed the example given by the JQuery UI documentation and haven't managed to get it to work. My html where I have my text field is: <div class="editor-field"> <input type = "text" name = "DatePublished" id = "Published" /> <%= Html.ValidationMessage("DatePublished" ,"*") %> </div> This HTML is in a partial view, lets call it pv.ascx, and it is called in the main page as a modal box: <div id = "ModalBox"> <% Html.RenderAction("pv", "Example"); %> </div> The thing is, that I try to call the datepicker creation anytime I enter the main page, and I do it in my javascript file app.js: $().ready(function() { var place = window.location.pathname; var placesplit = place.split("/"); //Depending on the location we are on, we execute different subroutines $('#Published').datepicker(); }); But nothing happens when I focus on the text field. What is wrong? Could it be that being called from a partial view it doesn't work? Thank you everyone, vikitor

  • How to convert an EntityCollection<T> to List<POCOObj>

    - by ggomez
    I have Entity Framework entities Events which have an EntityCollection of RSVP. I want to convert the EntityCollection of RSVP to a generic List< of a POCO class RSVP. So I want EntityCollection - List. What would be the best way to go about achieving this? So far I have this (it's missing the RSVP part) var events = from e in _entities.Event.Include("RSVP") select new BizObjects.Event { EventId = e.EventId, Name = e.Name, Location = e.Location, Organizer = e.Organizer, StartDate = e.StartDate, EndDate = e.EndDate, Description = e.Description, CreatedBy = e.CreatedBy, CreatedOn = e.CreatedOn, ModifiedBy = e.ModifiedBy, ModifiedOn = e.ModifiedOn, RSVPs = ??? }; Thanks.

  • Can't select View Content dropdown when adding view in MVC using Interfaces

    - by fearofawhackplanet
    I have my Model defined externally in two projects - a Core project and an Interface project. I am opening the Add View dialogue from my controller, and selecting Create a strongly typed view. In the drop down list, I can select the concrete types like MyProject.Model.Core.OrderDetails, but the interface types like MyProject.Model.Interface.IOrderDetails aren't there. I can type the interface class in manually and everything works, but then the View content menu that lets you select the Create, Delete, List, etc scaffolding is disabled. Is there some problem with using interfaces in MVC? Or is it something else I'm missing?

  • Basic refactoring features (e.g., Rename) unavailable when editing code in an aspx/ascx files

    - by DanM
    I was just editing some C# code between <% %> tags in an .ascx file, and I noticed that the Refactor contextual menu is unavailable. And even if I manually add items from this menu to a custom toolbar, they are disabled when viewing aspx/ascx files. I usually only have small snippets of C# code in my aspx/ascx files, but it would still be nice to be able to perform refactoring operations on any code that exists between <% %> tags. I feel like I'm going back to the dark ages when I have to use find/replace to change the name of a variable. Questions Is there a way to enable Visual Studio's refactoring features while viewing aspx/ascx files in Visual Studio? Are there any Visual Studio plug-ins (preferably free) that offer this kind of functionality?

  • IAuthenticationRequest.RedirectToProvider is not supposed to return, yet it does

    - by ripper234
    The method DotNetOpenAuth.OpenId.RelyingParty.IAuthenticationRequest.RedirectToProvider() is documented never to return: Redirects the user agent to the provider for authentication. Execution of the current page terminates after this call. However, it does return under the latest implementation (3.4.3). I'm using the following code: using (var relayingParty = new OpenIdRelyingParty()) { var response = relayingParty.GetResponse(); if (response == null) { // Stage 2: user submitting Identifier var openId = Request.Form["openId"]; relayingParty.CreateRequest(openId).RedirectToProvider(); throw new Exception("Never gets here"); } ... } (The line with "Never gets here" is reached). I need to return an ActionResult from this method ... Is this a known bug? Is there a aorkaround? Should I return EmptyResult? As far as I understand this is a bug - I submitted it in the project issue tracker.

  • How to html encode the output of an NHaml view (or any MVC view)?

    - by jessegavin
    I have several views written in NHaml that I would like to render as encoded html. Here's one. %table.data %thead %tr %th Country Name %th ISO 2 %th ISO 3 %th ISO # %tbody - foreach(var c in ViewData.Model.Countries) %tr %td =c.Name %td =c.Alpha2 %td =c.Alpha3 %td =c.Number I know that NHaml provides syntax to Html encode the output for given lines using &=. However, in order to encode the entire view, I would essentially lose the benefit of writing my view in NHaml since it would have to look like this.... &= "<table class='data'> &= " <thead> So I was wondering if there was any cool way to be able to capture the rendered view as a string, then to html encode that string. Maybe something like the following??? public ContentResult HtmlTable(string format) { var m = new CountryViewModel(); m.Countries = _countryService.GetAll(); // Somehow render the view and store it as a string? // Not sure how to achieve this. var viewHtml = View("HtmlTable", m); // ??? return Content(viewHtml); } This question may actually have no particular relevance to the View engine that I am using I guess. Any help or thoughts would be appreciated.

  • MVC 2 Conversion Disrupts the parameters passed to my Stored Procedure

  • Update panel in Tab Container

    - by Sam_Cogan
    I have a tab container with 5 tabs, each tab contains an update panel. When the user initially opens the form, they can only see the first Tab, the others are set to visible=false. Once they have completed the first form, the hit save which sends a partial postback to save the data to the DB. Once that is saved, I then want to set all the other tabs to visible, however this does not work at the moment, I am assuming because the tab container is not contained in an update panel. How can I get this to work, do I need to put the tab container in it's own update panel, which will obviously then contain all the other update panels, or should I not use an update panel in the first tab and do a full page postback?
