  • Creating Html Helper Method - MVC Framework

    - by nettguy
    I am learning MVC from Stephen Walther tutorials on MSDN website. He suggests that we can create Html Helper method. Say Example using System; namespace MvcApplication1.Helpers { public class LabelHelper { public static string Label(string target, string text) { return String.Format("<label for='{0}'>{1}</label>", target, text); } } } My Question under which folder do i need to create these class? View folder or controller folder? or can i place it in App_Code folder?

  • Customer provider Password Reset client.

    - by ProfK
    I'm looking for guidence on writing a custom password reset UI, but it must fit the Provider 'Pattern', or degrade silently to built-in defaults. E.g. my Reset Control must collect extra information, and perform differently to the standard Password Recovery Control. It must close as possible use the standard MembershipProvider interface for standard functions, and only use an extended interface for the non-standard stuff. I'd like some reading on issues such as, what must I ask the Membership Provider for, and what must I do myself. What must I tell the provider (service?) about what I do? Etc.

  • Passing page control from jscript to pagemethod in the codebehind?

    - by brandonprry
    Hi, I am looking write a javascript method as such called when a dropdownlist changes value function GetStuff(sender, destID){ var dest = document.getElementById(destID); this.PageMethods.GetStuffs(sender, dest, null, null); } GetStuffs() is in the Codebehind as follows: [WebMethod] public static void GetStuffs(object sender, object dest) { DropDownList s = sender as DropDownList; DropDownList d = dest as DropDownList; d.Items.Add(new ListItem(s.SelectedValue)); } I have a break point set at the method and alerts in the GetStuff() jscript method fire up until the PageMethod call, at which nothing happens. I have set OnSuccess and OnFailure methods up with alerts and they don't get fired. Any thoughts? Am I doing something inherently wrong?

  • MVC Pass textbox to controller if not in a form tag

    - by user1679820
    I am working on and Microsoft MVC3 project and cannot pass a parameter which has been edited to the controller. It will only pass back the original set parameter For example: @Ajax.ActionLink("share file", InviteController.Actions.Result, InviteController.Name, new { message = Model.Message }, new AjaxOptions { HttpMethod = "GET", UpdateTargetId = "popup", OnSuccess = "$('#popup').dialog('open')" }, new { id = "popup-button" }) <label>Personal Message <span class="optional-message">(optional)</span></label> @Html.TextAreaFor(x => x.Message) </div> This will pass the to the following controller but the 'message' parameter has the original message and not the updated message: public ActionResult Result(FormCollection coll, string message) { I'd love if someone could give me some advice. Many Thanks

  • updated validation example for web api

    - by MonkeyBonkey
    I tried the validation example code for web api on the latest mvc 4 download and I'm getting some errors. Does anyone have an updated example of the ValidationActionFilter class. Here's the original code public class ValidationActionFilter : ActionFilterAttribute { public override void OnActionExecuting(HttpActionContext context) { var modelState = context.ModelState; if (!modelState.IsValid) { dynamic errors = new JsonObject(); foreach (var key in modelState.Keys) { var state = modelState[key]; if (state.Errors.Any()) { errors[key] = state.Errors.First().ErrorMessage; } } context.Response = new HttpResponseMessage<JsonValue>(errors, HttpStatusCode.BadRequest); } } } I'm getting an error on HttpResponseMessage The non-generic type 'System.Net.Http.HttpResponseMessage' cannot be used with type arguments Also it looks like I need to add a Json reference, but should I be using JSON.net instead? An example of this using Json.net?

  • Event is causing an error, but I can't catch the exception

    - by proudgeekdad
    A developer has created a custom control in ASP.NET using VB.NET. The custom control uses a repeater. In certain scenarios, the rpt_ItemDataBound event is encountering a data error. My goal is rather than having the user see the yellow screen of death, give the user a friendlier error explaining exactly what the data error is. I figured I would be able to use a Try/Catch block as shown below throw the exception, however, it appears that the event has nowhere to be thrown to and stops executing at the "End Try" line. Protected Sub rpt_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rpt1.ItemDataBound, rpt2.ItemDataBound Try ProcessBadData... Catch ex As Exception Throw ex End Try End Sub In VB.NET, I can find where the repeater's DataSource is being set, however, I can not find a DataBind event. Any ideas how I can capture the exception in this ASCX control so I can report it to the user?

  • Action method expected parameter named Id and nothing otherwise

    - by codingbiz
    The Error The parameters dictionary contains a null entry for parameter 'UserId' of non-nullable type 'System.Int64' for method 'System.Web.Mvc.ActionResult Predict(Int64)' in 'sportingbiz.Controllers.PredictionController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter. Parameter name: parameters This does not work. Throws the error mentioned above http://mysite/User/Profile/15 This works http://mysite/User/Profile/?UserID=15 The Controller Action public ActionResult Profile(long UserID) { } When I changed the parameter name to Id it works. I think it's because Id was specified in the route collection (Global.asax). Is it possible to tell MVC that UserId should map to Id without changing it in the Global.asax

  • 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?

  • result set using two different views (from an if statement)

    - by mailman1979
    Hi All, I have a bit of code that works with a result set called "result" (original I know) but depending on the incoming variable I'd like to fire the specific query depending. I have the below in an if statement but that just makes the "result" recordset gets those nasty red lines and it doesn't work. I'm sure this is easy to work out. if (area == "dashboard") { IQueryable<ViewGetNavigationMainItem> result = (from m in _entities.ViewGetNavigationMainItems where m.area.Trim() == area.Trim() where m.state == "Online" where m.parentID == parentID orderby m.sequence ascending select m); } else { //Get the Content Items IQueryable<ViewGetNavigationContentItem> result = (from m in _entities.ViewGetNavigationContentItems where m.navID == navID where m.parentID == parentID orderby m.contentOrder ascending select m); } maxRecords = result.Count(); foreach (var item in result) { etc etc etc

  • MVC4 not binding a list of basic types

    - by admanb
    I cannot, for the life of me, get this data to bind. Here's my JavaScript: var params = { 'InvItemIDs': ["188475", "188490"]}; $.post("api/Orders/OrderFromInventory?" + $.param(params)) and the Controller action: public HttpResponseMessage OrderFromInventory(IList<int> InvItemIDs) { return new HttpResponseMessage(); } I've built the query string so that it's sending: ?InvItemIDs=188475&InvItemIDs=188490 as well as ?InvItemIDs[]=188475&InvItemIDs[]=188490 and even ?InvItemIDs[0]=188475&InvItemIDs[1]=188490 and none of them are binding. InvItemIDs is always null. What am I doing wrong? EDIT: So it turns out all this is a bug (or something) in the new Web API controller code in MVC4. As soon as I moved the exact same code over to a standard controller it started working. I'm still interested if anyone has any insight as to why the Web API would break this binding.

  • Lucene.Net - How to treat a space-seperated phrase as a single token?

    - by Gareth D
    I've implemented a search facility using Lucene.Net. The index includes UK academic qualifications, including "A Level". I'd like the users to be able to search using the phrase "A Level", but using the Standrad Analyser the "A" is stripped out as a stop-word and therefore only "Level" is indexed/searched. What's my best option to work around this? I'm guessing I need to somehow tokenise "A Level" to "A-Level" or similar by creating a custom analyser. Is this the best approach? Note that I want don't want the whole search to be a phrase query. i.e. in my search box I want the user to be able to enter <"A Level" AND English Maths Physics and this would return any with "A Level" and either of English MAths or Physics. Question updated to reflect this.

  • What is the easiest way to deploy a MVC2 application from Visual Studio 2010 to IIS 7.5?

    - by Richard
    I´ve tried a couple of different ways to deploy a application to a IIS 7.5 running on my machine for testing purposes and i´ve sort of hit a wall. Nothing works out of the box. Everything assumes I have knowledge I don't have and would prefer not to have to aqquire. Google isn't really helping either with answers ranging from "copy files by hand" to "install teamcity and set it up for CI". I have set up TeamCity for java projects before and it's really over kill for my needs at the moment. So anyone know of a fast, simple and easy way to deploy a application during testing/building?

  • Custom librairies with Razor with the release version of MVC 3

    - by Maxim
    So I'm developing an in-house library for MVC 3 and I want to add it to my project. I added it to my web.config. I added the assembly and added it to the pages - namespaces section and... no. Doesn't work. I tried recompiling, etc... but Razor doesn't like it at all. It's not an intellisense problem... the site can't run if I use my defined namespace. The only way that I made it work was by using the following statements: @using Sample.Helpers I don't want to use it in the pages. I want to be able to deploy it to many projects and adding it to the web.config is definitely the way to go. Anyone ran into this problem?

  • How to override [Authorize] attribute in the MVC Web API?

    - by NullReference
    I have a MVC Web Api Controller that uses the [Authorize] attribute at the class level. This makes all of the api methods require authorization but I'd like to create an attribute called [ApiPublic] that overrides the [Authorize] attribute. There is a similar technique described here for normal MVC controllers. I tried creating an AuthorizeAttribute based of the System.Web.Http.AuthorizeAttribute but none of the overridden events are called if I put it on a api method that has the [Authorize] at the class level. Anyone have an idea how to override the authorize for the web api? [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)] public class ApiPublicAttribute : AuthorizeAttribute { protected override void HandleUnauthorizedRequest(System.Web.Http.Controllers.HttpActionContext actionContext) { base.HandleUnauthorizedRequest(actionContext); } public override void OnAuthorization(System.Web.Http.Controllers.HttpActionContext actionContext) { base.OnAuthorization(actionContext); } protected override bool IsAuthorized(System.Web.Http.Controllers.HttpActionContext actionContext) { return true; } }

  • Modern way to validate POST-data in MVC 2

    - by zerkms
    There are a lot of articles devoted to working with data in MVC, and nothing about MVC 2. So my question is: what is the proper way to handle POST-query and validate it. Assume we have 2 actions. Both of them operates over the same entity, but each action has it's own separated set of object properties that should be bound in automatic manner. For example: Action "A" should bind only "Name" property of object, taken from POST-request Action "B" should bind only "Date" property of object, taken from POST-request As far as I understand - we cannot use Bind attribute in this case. So - what are the best practices in MVC2 to handle POST-data and probably validate it.

  • Why does GetExportedValues<T>() no longer work after using the .net 4 final version of MEF?

    - by BigJason
    I have been developing a managed extensibility framework application for the last several months using the community preview. I have been using the GetExportedValues() method and the PartCreationPolicy(CreationPolicy.NonShared) to fake a class factory (since only the silverlight version supports a factory). This was working great until I upgraded the project to use .net 4.0. There is no error, it just doesn't work. So why did this code stop working? The code follows: The factory method: public static IEnumerable<DataActionBase> GetActionsFromDirectory(string PluginsFolder) { IEnumerable<DataActionBase> result = null; var catalog = new DirectoryCatalog(PluginsFolder); var container = new CompositionContainer(catalog: catalog); result = container.GetExportedValues<DataActionBase>(); return result; } Example Export Class: [Export(typeof(DataActionBase))] [PartCreationPolicy(CreationPolicy.NonShared)] public class AnAction : DataActionBase { .... }
