  • MVC 4 Authentication

    - by Aligned
    First: After searching for awhile to figure out what’s new/different with MVC 4 and forms authentication, this is the best article I've found on the subject: http://weblogs.asp.net/jgalloway/archive/2012/08/29/simplemembership-membership-providers-universal-providers-and-the-new-asp-net-4-5-web-forms-and-asp-net-mvc-4-templates.aspx Some quotes from the article: “The ASP.NET Web Pages team designed SimpleMembership to (wait for it) simplify the task of dealing with membership” "WSAT is built to work with ASP.NET Membership, and is not compatible with Simple Membership. There are two main options there: Use the WebSecurity and OAuthWebSecurity API to manage the users and roles Create a web admin using the above APIs Since SimpleMembership runs on top of your database, you can update your users as you would any other data - via EF or even in direct database edits (in development, of course)" “If you want to use an existing ASP.NET Membership Provider in ASP.NET MVC 4, you can't use the new AccountController. You can do a few things:” “Universal Providers do not work with Simple Membership.” ~ this post (look for Bob.at.SBS’s answer) says Universal Providers is not needed for MVC 4 to work in Azure)   I've been trying to figure out the Forms Authentication in MVC4. It's different than the past approach (aspnet_regsql). If you do file new project -> MVC 4 -> internet application, you get a really nice template with the controller and model setup for you. However, the tables are different than using aspnet_regsql and the ASP.Net Configuration tool (WSAT) wasn’t connecting to the data I had (it was creating an App_Data/aspnet.mdf file, which I didn’t see right away). Points of Note The database tables are created in the SimpleMembershipInitializer class, when you first run your app using Entity Framework 5 migration functionality. The tables created are webpages_Membership, webpages_OAuthMembership, webpages_Roles, webpages_UsersInRoles, UserProfile. Web.config settings don’t seem to be needed.   Scott Hanselman on Universal Providers was also useful if not somewhat out dated. Universal Providers and SimpleMembership are not compatible. http://www.asp.net/web-pages/tutorials/security/16-adding-security-and-membership – walk-through

  • Using DisplayFor inside a display template

    - by Oenotria
    I've created a htmlhelper extension to reduce the amount of repetitive markup when creating forms: public static MvcHtmlString RenderField<TModel, TValue>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TValue>> expression) { return htmlHelper.DisplayFor(expression, "formfield"); } The idea being that inside my views I can just write @Html.RenderField(x=>x.MyFieldName) and it will print the label and the field's content with the appropriate div tags in place already. Inside the displaytemplates folder I have created formfield.cshtml containing the following: <div class="display-group"> <div class="display-label"> @Html.LabelFor(x => x) </div> <div class="display-field"> @Html.DisplayFor(x => x) </div> </div> Unfortunately it doesn't appear that it is possible to nest DisplayFor inside a display template (it doesn't render anything). I don't want to just using @Model because then I won't get checkboxes for boolean values, calendar controls for dates etc. Is there a good way around this?

  • Jquery validation in asp.net mvc

  • Is it possible to auto update only selected properties on an existent entity object without touching the others

    - by LaserBeak
    Say I have a bunch of boolean properties on my entity class public bool isActive etc. Values which will be manipulated by setting check boxes in a web application. I will ONLY be posting back the one changed name/value pair and the primary key at a time, say { isActive : true , NewsPageID: 34 } and the default model binder will create a NewsPage object with only those two properties set. Now if I run the below code it will not only update the values for the properties that have been set on the NewsPage object created by the model binder but of course also attempt to null all the other non set values for the existent entity object because they are not set on NewsPage object created by the model binder. Is it possible to somehow tell entity framework not to look at the properties that are set to null and attempt to persist those changes back to the retrieved entity object and hence database ? Perhaps there's some code I can write that will only utilize the non-null values and their property names on the NewsPage object created by model binder and only attempt to update those particular properties ? [HttpPost] public PartialViewResult SaveNews(NewsPage Np) { Np.ModifyDate = DateTime.Now; _db.NewsPages.Attach(Np); _db.ObjectStateManager.ChangeObjectState(Np, System.Data.EntityState.Modified); _db.SaveChanges(); _db.Dispose(); return PartialView("MonthNewsData"); } I can of course do something like below, but I have a feeling it's not the optimal solution. Especially considering that I have like 6 boolean properties that I need to set. [HttpPost] public PartialViewResult SaveNews(int NewsPageID, bool isActive, bool isOnFrontPage) { if (isActive != null) { //Get entity and update this property } if (isOnFontPage != null) { //Get entity and update this property } }

  • Pattern to iterate Request Params

    - by NOOBie
    My view is not a strongly typed view and I need to iterate through Request Params in the controller action to determine the values posted. Is there a better way to iterate through the nameValueCollection AllKeys? I am currently looping through the Request Params and setting values appropriately. foreach (var key in Request.Params.AllKeys) { if (key.Equals("CustomerId")) queryObject.CustomerId = Request.Params[key]; else if (key.Equals("OrderId")) queryObject.OrderId= Request.Params[key]; //and so on } I see a considerable amount of repetition in this code. Is there a better way to handle this?

  • Partial view is not rendering within the main view it's contained (instead it's rendered in it's own page)?

    - by JaJ
    I have a partial view that is contained in a simple index view. When I try to add a new object to my model and update my partial view to display that new object along with existing objects the partial view is rendered outside the page that it's contained? I'm using AJAX to update the partial view but what is wrong with the following code? Model: public class Product { public int ID { get; set; } public string Name { get; set; } [DataType(DataType.Currency)] public decimal Price { get; set; } } public class BoringStoreContext { List<Product> results = new List<Product>(); public BoringStoreContext() { Products = new List<Product>(); Products.Add(new Product() { ID = 1, Name = "Sure", Price = (decimal)(1.10) }); Products.Add(new Product() { ID = 2, Name = "Sure2", Price = (decimal)(2.10) }); } public List<Product> Products {get; set;} } public class ProductIndexViewModel { public Product NewProduct { get; set; } public IEnumerable<Product> Products { get; set; } } Index.cshtml View: @model AjaxPartialPageUpdates.Models.ProductIndexViewModel @using (Ajax.BeginForm("Index_AddItem", new AjaxOptions { UpdateTargetId = "productList" })) { <div> @Html.LabelFor(model => model.NewProduct.Name) @Html.EditorFor(model => model.NewProduct.Name) </div> <div> @Html.LabelFor(model => model.NewProduct.Price) @Html.EditorFor(model => model.NewProduct.Price) </div> <div> <input type="submit" value="Add Product" /> </div> } <div id='productList'> @{ Html.RenderPartial("ProductListControl", Model.Products); } </div> ProductListControl.cshtml Partial View @model IEnumerable<AjaxPartialPageUpdates.Models.Product> <table> <!-- Render the table headers. --> <tr> <th>Name</th> <th>Price</th> </tr> <!-- Render the name and price of each product. --> @foreach (var item in Model) { <tr> <td>@Html.DisplayFor(model => item.Name)</td> <td>@Html.DisplayFor(model => item.Price)</td> </tr> } </table> Controller: public class HomeController : Controller { public ActionResult Index() { BoringStoreContext db = new BoringStoreContext(); ProductIndexViewModel viewModel = new ProductIndexViewModel { NewProduct = new Product(), Products = db.Products }; return View(viewModel); } public ActionResult Index_AddItem(ProductIndexViewModel viewModel) { BoringStoreContext db = new BoringStoreContext(); db.Products.Add(viewModel.NewProduct); return PartialView("ProductListControl", db.Products); } }

    I am having a model and I am using ajax.post. I can see that the model binding isn`t being done for the arraylists in my model, though binding done for the properties of int or string type. Why is that so? My code is as below. I have a model with the following properties public class ProjectModel { public int ID { get; set; } public ArrayList Boys= new ArrayList(); } In my view I have $(document).ready(function () { var project = new Object(); var Boys= new Array(); var ID; ....... ID = $('#ID').val(); project.Boys= Boys; ..... $.ajax({ type: "POST", url: '<%=Url.Action("Create","Project") %>', data: JSON.stringify(project), contentType: "application/json; charset=utf-8", dataType: "html", success: function () { }, error: function (request, status, error) { } }); // My controller [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(ProjectModel project) { try { project.CreateProject(); return RedirectToAction("Index"); } ....

  • asp.net mvc 2 multithread

    - by Chris Cap
    I'm getting some weird behavior in asp.net MVC2 (at least it's not what I'm expecting). I have a controller httppost action that processes credit cards. I'm setting a session variable on the server to let me know if a user has attempted to process a card. I clear that session variable when I'm done. I am doing some very quick posts to test the process and the session variable is coming back null everytime because I clear the session variable at the end of the process. I have some debug prints that show me that the all requests are processed synchronously. That is...the first attempt occurs, it fails, session variable is cleared, second attempt tries and fails and the variable is cleared, etc... My first thought was that this was a side effect of debugging and that it just lined requests up for debugging purposes using the local webserver. So I put it on a development server and the same thing is occurring. Multiple submits/posts are processed synchronously. I even put a System.Threading.Sleep in there to make sure it would stop right after I set the session variable and it still won't even START the second request until the first is done. Has anyone else seen this behavior? My understanding was that a worker process was spawned for each request and that these actions could happen asychronously. Here's some psuedo code if (Session["CardCharged"] != null) return RedirectToAction("Index", "Problem"); Session["CardCharged"] = false; //starting the process System.Threading.Thread.Sleep(10000); //charge card here if (!providerResponse.IsApproved) { System.Diagnostics.Debug.WriteLine("failed"); Session["CardCharged"] = null; //have to allow them to charge again since this failed return View(myModel); } Session["CardCharged"] = true; return RedirectToAction("Index", "OrderComplete"); I should mention that my code ALWAYS fails the credit card check for testing purposes. I'm trying to test the situation where processing is STILL occurring and redirect the user elsewhere. I have set a dummy session variable elsewhere to assure that the session id "sticks". So I know the session id is the same for each request. Thanks

  • How to use RedirectToAction to redirect to the default action of different controller?

    - by atbebtg
    I am trying to do a RedirectToAction from http://mywebsite/Home/ using the following code: return RedirectToAction("Index","Profile", new { id = formValues["id"] }); The above code will succesfully take me to http://mywebsite/Profile/Index/223224 What do I have to do to make it redirect to http://mywebsite/Profile/223224 Thank you. I figured out how to do this. First I have to add custom route rule: routes.MapRoute("Profile", "Profile/{id}", new { controller = "Profile", action = "Index", id = UrlParameter.Optional }); Then I can do the following: [AcceptVerbs(HttpVerbs.Post)] public RedirectResult Index(FormCollection formValues) { return Redirect("~/Survey/" + formValues["Id"]); }
