  • ASP.NET MVC4: How to convert an IEnumerable to a string for ViewBag

    - by sehummel
    This is what I'm trying to do, but it doesn't work: HardwareType hwt = new HardwareType { HType = "PC" }; IEnumerable<Hardware> Pcs = db.Hardware.Where(h => h.HardwareType.Contains(hwt)); ViewBag.Pcs = Pcs.ToString(); So how do I convert my IEnumerable to a string (or other primitive data type) so the compiler won't give me an error when I try to use it in my Razor? @foreach (var item in ViewBag.Pcs) { <li><a href="#" class="btn"><i class="icon-hdd"></i> @item.HType</a></li> }

  • Asp.Net MVC How to test that the view rendered

    - by Miau
    HI there I was wondering if there is a better way of testing that a view has rendered in MVC. I was thinking perhaps I should render the view to a string but perhaps there are simpler methods? Basically what I want to know if that the view for a given action has rendered without errors I m already testing the view model but I want to see that rendering the view giving a correct ViewData.Model works

  • ASP.Net MVC - Models and User Controls

    - by cdotlister
    Hi guys, I have a View with a Master Page. The user control makes use of a Model: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<BudgieMoneySite.Models.SiteUserLoginModel>" %> This user control is shown on all screens (Part of the Master Page). If the user is logged in, it shows a certain text, and if the user isn't logged in, it offers a login box. That is working OK. Now, I am adding my first functional screen. So I created a new view... and, well, i generated the basic view code for me when I selected the controller method, and said 'Create View'. My Controller has this code: public ActionResult Transactions() { List<AccountTransactionDetails> trans = GetTransactions(); return View(trans); } private List<AccountTransactionDetails> GetTransactions() { List<AccountTransactionDto> trans = Services.TransactionServices.GetTransactions(); List<AccountTransactionDetails> reply = new List<AccountTransactionDetails>(); foreach(var t in trans) { AccountTransactionDetails a = new AccountTransactionDetails(); foreach (var line in a.Transactions) { AccountTransactionLine l = new AccountTransactionLine(); l.Amount = line.Amount; l.SubCategory = line.SubCategory; l.SubCategoryId = line.SubCategoryId; a.Transactions.Add(l); } reply.Add(a); } return reply; } So, my view was generated with this: <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<System.Collections.Generic.List<BudgieMoneySite.Models.AccountTransactionDetails>>" %> Found <%=Model.Count() % Transactions. All I want to show for now is the number of records I will be displaying. When I run it, I get an error: "The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[BudgieMoneySite.Models.AccountTransactionDetails]', but this dictionary requires a model item of type 'BudgieMoneySite.Models.SiteUserLoginModel'." It looks like the user control is being rendered first, and as the Model from the controller is my List<, it's breaking! What am I doing wrong?

  • Javascript update before page loads in ASP.NET

    - by user204588
    Hello, I'm trying to update values from a xml file into textboxes. I have this javascript being called in the Page_Load event this.Page.ClientScript.RegisterStartupScript(this.GetType(), "Script", sb.ToString(), true); I click the continue button which does a post back but the values are not updated until I refresh the page again which makes me think the js isn't being run until after the page is returned. I'm wondering how to have the values updated when the page is refreshed after the button postback. thanks

  • Creating a Month Dropdown in C# ASP.NET MVC

    - by Chris M
    This method seems stupid and a bit heavy; is there a more optimal way of creating the same thing (its for an MVC View Dropdown) private List<KeyValuePair<int, string>> getMonthListDD { get { var dDur = new List<KeyValuePair<int, string>>(); dDur.Add(new KeyValuePair<int, string>(1, "January")); dDur.Add(new KeyValuePair<int, string>(2, "Febuary")); dDur.Add(new KeyValuePair<int, string>(3, "March")); dDur.Add(new KeyValuePair<int, string>(4, "April")); dDur.Add(new KeyValuePair<int, string>(5, "May")); dDur.Add(new KeyValuePair<int, string>(6, "June")); dDur.Add(new KeyValuePair<int, string>(7, "July")); dDur.Add(new KeyValuePair<int, string>(8, "August")); dDur.Add(new KeyValuePair<int, string>(9, "September")); dDur.Add(new KeyValuePair<int, string>(10, "October")); dDur.Add(new KeyValuePair<int, string>(11, "November")); dDur.Add(new KeyValuePair<int, string>(12, "December")); return dDur; } }

  • ASP.MVC ModelBinding Behaviour

    - by OldBoy
    This one has me stumped, despite the numerous posts on here. The scenario is a basic MVC(2) web application with simple CRUD operations. Whenever the edit form is submitted and the UpdateModel() called, an exception is thrown: System.Data.Linq.ForeignKeyReferenceAlreadyHasValueException was unhandled by user code This occurs against a DropDownList value which is a foreign key on the entity table. However, there is another DropDownList list on the form, representing another foreign key, which does not throw the error (unsurprisingly). Changing the property values manually inside the Edit Action: Recipe recipe = repository.GetRecipe(int.Parse(formValues["recipeid"])); recipe.CategoryId = Convert.ToInt32(formValues["CategoryId"].ToString()); recipe.Page = int.Parse(formValues["Page"].ToString()); recipe.PublicationId=Convert.ToInt32(formValues["PublicationId"].ToString()); Allows the CategoryId and Page properties to be updated, and then the error is thrown on the PublicationId. All of the referential integrity is checked an the same in the db and the dbml. Any light shed on this would be most welcome.

  • ASP.NET MVC 2 Model object validation

    - by Jimmy
    Hey guys, I'm trying to validate a model object outside of the context of ModelState within a controller, I currently have a parser that creates model objects from an excel file and I want to be able to report how many entries were added to the database and how many failed, is there a way to validate a model object on its data annotations outside of model binding? I'm looking for something similar to the rails model method of model.valid? or a way for me to implement that myself. My current solution is just manually checking if a few key fields are present but this duplicates requirements between my model class and its metadata, there has to be a better way to hook into the model validation checking that is done by mvc 2. Thanks

  • Runtime Error in asp.net?(online )

    - by Surya sasidhar
    hi, I develop a web application it is working fine in local. When i upload the site in online through CuteFTP it is showing the error like this... Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off". Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL. please help me i place the but even though it is not working it is giving same error. Thank you

  • Asp.net mvc class reference in session

    - by Billy
    Hi, if I put a custom class in session, then in an action method I get an instance of that class from session, and populate some fields, I noticed that when a different controller gets that class from session, those fields are populated. Even though after the first call didn't save the updated class back in session. is this typical behavior for session objects? I thought I had to use keyword 'static' on the class in session for this to happen thanks

  • Passing additional data value to strongly typed partial views in ASP.NET MVC

    - by fearofawhackplanet
    I have an OrderForm domain class, which has property subclasses, something like: interface IOrderForm { int OrderId { get; } ICustomerDetails CustomerDetails { get; set; } IDeliveryDetails DeliveryDetails{ get; set; } IPaymentsDetails PaymentsDetails { get; set; } IOrderDetails OrderDetails { get; set; } } My "Details" view is strongly typed inheriting from IOrderForm. I then have a strongly type partial for rendering each section: <div id="CustomerDetails"> <% Html.RenderPartial("CustomerDetails", Model.CustomerDetails); %> </div> <div id="DeliveryDetails"> <% Html.RenderPartial("DeliveryDetails", Model.DeliveryDetails); %> </div> ... etc This works ok up to this point, but I'm trying to add some nice ajax bits for updating some parts of the order form, and I've realised that each of my partial views also needs access to the IOrderForm.OrderId. Whats the easiest way to give my partials access to this value?

  • How do i provide a custom session ID getter/setter in asp.net

    - by Monsters
    I want to pass the sessionID as a json parameter, I can see how to override SessionIDManager and such, but this just covers custom creation/validation of sessionID's as opposed to where it actually gets the sessionID from. There is of course 'cookieless' which puts it in the url, but that doesn't work for me either. So i'd like to override the session handling so I can specify where it should look for the sessionID.

Why is that and how can I cache the images for the next year.

  • Hiding Url for asp.net page

    - by user204588
    Hello, I'm creating an html page that is posted to another page for processing. I don't want users to see the weird URL they are redirected to and I was using FRAMES but I can't figure out how to add my HTML page dynamically because I need the variables and either add frames or try another way to accomplish this. So, based on how I'm creating the page below, how can I hide the URL and add something that I want. Here is how I'm creating the page. StringBuilder sb = new StringBuilder(); sb.Append("<html><head></head>"); sb.Append("<body onload=\"document.frmLaunch.submit();\">"); sb.Append("<form name=\"frmLaunch\" action=\"" + variableTargetURL + "\" method=\"post\">"); sb.Append("<input type=hidden name=\"testVariable\" value=\"" + variableTest + "\">"); sb.Append("</form>"); sb.Append("</body></html>"); HttpResponse response = HttpContext.Current.Response; response.Clear(); response.Write(sb.ToString()); response.End();
