  • ASP.NET MVC 2 RC2 Model Binding with NVARCHAR NOT NULL column

    - by Gary McGill
    I have a database column defined as NVARCHAR(1000) NOT NULL DEFAULT(N'') - in other words, a non-nullable text column with a default value of blank. I have a model class generated by the Linq-to-SQL Classes designer, which correctly identifies the property as not nullable. I have a TextAreaFor in my view for that property. I'm using UpdateModel in my controller to fetch the value from the form and populate the model object. If I view the web page and leave the text area blank, UpdateModel insists on setting the property to NULL instead of empty string. (Even if I set the value to blank in code prior to calling UpdateModel, it still overwrites that with NULL). Which, of course, causes the subsequent database update to fail. I could check all such properties for NULL after calling UpdateModel, but that seems ridiculous - surely there must be a better way? Please don't tell me I need a custom model binder for such a simple scenario...!

  • ASP.NET MVC 2 Post AJAX from from JavaScript

    - by ANDyW
    Hi, I got control with strongly typed View, with Ajax.BeginForm(). Now I would like to change submit method from <input type="submit" id="testClick" value="Submit" /> To some javascript method DoSubmit(). What I tried is : Invoke click on that submit button Invoke submit on form ('form1').submit(), document.forms['form1'].submit() jQuery forms with ('form1').AjaxSubmit(); Create jQuery AJAX $.ajax({ type: "POST", url: $("#form1").attr("action"), data: $("#form1").serialize(), success: function() { alert("epic win!!!1!1!") }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert("epic fail!") } }); All those method created normal request (not AJAX), or they didn't work. So anyone know how I can do AJAX submit "Form", from JavaScript and strongly typed mechanism (public AcrionResult MyFormAction(FormModel model); ) will work?

  • Sharing sessions across applications using the ASP.NET Session State Service

    - by Dan
    I am trying to share sessions between two web applications, both hosted on the same server. One is a .net 2.0 web forms application the other is as .net 3.5 MVC2 application. Both apps have their session set up like this: <sessionState mode="StateServer" stateConnectionString="tcpip=127.0.0.1:42424" /> In the webform application I am posting the the session key to the MVC app: protected void LinkButton1_Click(object sender, EventArgs e) { Session["myvariable"] = "dan"; string sessionKey = HttpContext.Current.Session.SessionID; //Followed by some code that posts sessionKey to the other application } I then recieve it in the MVC application and try use the same session like this: [HttpPost] public void Recieve(string sessionKey ) { var manager = new SessionIDManager(); bool redirected; bool IsAdded; manager.SaveSessionID(HttpContext.ApplicationInstance.Context, Id, out redirected, out IsAdded); var sessionKey = Session["myvariable"]; } The key is being posted but the session does not seem to get loaded in the MVC app, i.e. sessionKey is null. Can what I am trying to do be done?

  • [ASP.NET MVC] Ajax.BeginForm doesn't work asynchronously

    - by Tony
    Hi, I've read the article http://davidhayden.com/blog/dave/archive/2009/05/19/ASPNETMVCAjaxBeginForm.aspx and now I have small problem with that code: <%using (Ajax.BeginForm("ChangeData", new AjaxOptions { UpdateTargetId = "myLabel" })) { %> <input id="mbutton" type="submit" value="blabla" /> <%} %> <label id="myLabel"></label> then, in the MyBookController.cs is the code to be invoked asynchronous: public ActionResult ChangeData() { return Content("OK"); } but, it doesn't work asynchronously, the compiler doesn't go inside that method

  • asp.net mvc cookies not being sent back

    - by brian b
    My application at mysubdomain.mydomain.com needs to set a cookie that contains some user session information. They log in at a https page. We authenticate them and set some session info in a cookie. We do this in a helper library that takes in the controller context contextBase.Response.Cookies[CookiePayload.CookieName].Value = encryptedTicket; contextBase.Response.Cookies[CookiePayload.CookieName].Expires = cookieExpires; contextBase.Response.Cookies[CookiePayload.CookieName].Domain= ConfigHelper.CookieDomain; contextBase.Response.Cookies[CookiePayload.CookieName].HttpOnly=true; We do a quick redirect in the controller (to a non https page): this.ControllerContext.HttpContext.Response.Redirect(redirectTo, false); return null; The cookie appears in the response (according to firebug's net tab). But neither fireforx nor ie send the cookie on subsequent gets. We are setting the cookie domain to mydomain.com even though the site is mysubdomain.mydomain.com. Skipping the redirect command has no effect, nor does changing the cookie value. I'm baffled. Thanks for any suggestions.

  • ASP.NET MVC: ModelState vs. ModelStateDictionary

    - by Alex
    Hello, I have a service which has a method that's called when a certain controller method is triggered. My service returns a custom result object PlacementResult in which I want to communicate errors that may have happened (validation) back to the controller method. Should PlacementResult have a ModelState or a ModelStateDictionary to communicate errors back to the controller (and finally view)? How would I string this together? Finally, how do I get the ModelState/ModelStateDictionary (whichever you tell me I should choose) back into the view (highlighting the appropriate text box, show the error message etc.)? Thank you !

  • Providing or Filtering assemblies when registering areas for an ASP.NET MVC 2.0 application

    - by HackedByChinese
    I have a large application that currently exists as a hybrid of WebForms and MVC 2.0. Startup of my application is dreadful, and the culprit is primarily because of the AreaRegistration.RegisterAllAreas call. More specifically, that it is using the System.Web. Compilation.BuildManager.GetReferencedAssemblies to enumerate all types in assemblies directly referenced by the application and test them to see if they derive from AreaRegistration. Unfortunately, I have a number of third-party assemblies that happen to be quite extensive, so this initial load can be pretty bad. I'd have much better results if I could tell it which assemblies to look for AreaRegistrations, or even register areas manually for the time being. I can gather up all the internals of AreaRegistration to create and invoke the registration, but I'm just curious if others have had and worked around this issue.

  • ASP.Net MVC: "Random" URLs getting generated by URL.Action

    - by Daniel Magliola
    I have 2 very similar routes, just because i'm trying to generate two different URLs for the same resource (same Controller/Action), and both are very similar. These are the routes definitions: routes.MapRoute("Post2.Mp3", "sites/{siteSlug}/post/{brand}/aconstant-{slug}.mp3", new { controller = "Posts", action = "Mp3" }, new { siteSlug = @"[A-Za-z0-9-_]+", slug = @"[^(aconstant\-)][A-Za-z0-9-_]+", brand = @"[A-Za-z0-9-_]+" }); routes.MapRoute("Post.Mp3", "sites/{siteSlug}/post/{slug}.mp3", new { controller = "Posts", action = "Mp3" }, new { siteSlug = @"[A-Za-z0-9-_]+", slug = @"[A-Za-z0-9-_]+" }); "brand" is going to be my site name, which is the same as "aconstant" in those routes. Now, if I try this: Url.Action("ShowMp3", "Posts", new { siteSlug = post.Site.Slug, slug = post.Slug, origin = "origfeedwithaudio", brand = "aconstant" }) sometimes I get the URL I expect: /sites/site-Name/post/aconstant/aconstant-post-Name.mp3 but sometimes, I get this: /sites/site-Name/post/post-Name.mp3?brand=aconstant By sometimes, I mean that different sets of "slugs" give me one or the other. I haven't seen the same set of slugs give me different URLs. I haven't found any reasonable rule for when i'm getting one or the other, it seems random. What is going on here? How can I be getting different URLs based on esentially the same arguments? Thanks! Daniel

  • asp mvc unit test HttpContext.Current.Cache?

    - by Paul Creasey
    Here is the first part of my controller code: public class ControlMController : Controller { IControlMService _controlMservice; public IList<User> Users { get { if (System.Web.HttpContext.Current.Cache["users"] == null) { System.Web.HttpContext.Current.Cache["users"] = _controlMservice.GetUsers(); } return (IList<User>)System.Web.HttpContext.Current.Cache["users"]; } } public ControlMController(IControlMService controlMservice) { this._controlMservice = controlMservice; var users = Users; ViewData["Users"] = users; ViewData["jqSelectUsers"] = string.Join(";", users.Select(x => x.UserID + ":" + x.Name).ToArray()); } I'm trying to test it, and because i'm caching using the HttpContext, i'm struggling with null reference exceptions. I've tried using MvcContrib.TestHelper; here is my sample test... [TestMethod] public void EventDetails_Returns_view_with_correct_event() { var builder = new TestControllerBuilder(); var controller = builder.CreateController<ControlMController>( new ControlMService( new MockControlMRepository() )); var view = (controller.EventDetails(1) as ViewResult); Assert.AreEqual(1, (view.ViewData.Model as Event).EventId); } (I haven't quite got round to using DI for my tests! I'm still getting the same null reference exception when the code hits the httpcontext: Error 1 TestCase 'SupportTool.Tests.Services.ControlM.ControlMControllerTests.EventDetails_Returns_view_with_correct_event' failed: System.NullReferenceException: Object reference not set to an instance of an object. at SupportTool.web.Controllers.ControlMController.get_Users() Any ideas?

  • ASP .NET MVC; return HTML along with JavaScript

    - by effkay
    I have a partial view which renders a table. On page load, I am using JQuery to perform Zebra Stripping on it. Whenever ajax refreshes the table, DOM elements are updated, but since JQuery code to do the Zebra Stripping is not executed; table looks ugly. I have tried adding Javascript in my partial view if( Request.IsAjaxRequest() ) return PartialView( "AdministrationGrid", Users ); but javascript is not executed. I guess the only way to execute the Javascript as reply is to do: return JavaScript( "alert( '' )" ); Anyone with an idea how can I achieve this? I thought about JQuery Live, but it is used to bind itself to events.

  • ASP.NET MVC 2: Mechanics behind an Order / Order Line in a edit form

    - by Dr. Zim
    In this question I am looking for links/code to handle an IList<OrderLine> in an MVC 2 edit form. Specifically I am interested in sending a complete order to the client, then posting the edited order back to an object (to persist) using: Html.EditorFor(m = m.orderlines[i]) (where orderlines is an enumerable object) Editing an Order that has multiple order lines (two tables, Order and OrderLine, one to many) is apparently difficult. Is there any links/examples/patterns out there to advise how to create this form that edits an entity and related entities in a single form (in C# MVC 2)? The IList is really throwing me for a loop. Should I have it there (while still having one form to edit one order)? How could you use the server side factory to create a blank OrderLine in the form while not posting the entire form back to the server? I am hoping we don't treat the individual order lines with individual save buttons, deletes, etc. (for example, they may open an order, delete all the lines, then click cancel, which shouldn't have altered the order itself in either the repository nor the database. Example classes: public class ViewModel { public Order order {get;set;} // Only one order } public class Order { public int ID {get;set;} // Order Identity public string name {get;set;} public IList<OrderLine> orderlines {get;set;} // Order has multiple lines } public class OrderLine { public int orderID {get;set;} // references Order ID above public int orderLineID {get;set;} // Order Line identity (need?) public Product refProduct {get;set;} // Product value object public int quantity {get;set;} // How many we want public double price {get;set;} // Current sale price }

  • ASP.net MVC 2 and MonoDevelop 2.2

    - by rifferte
    Is it possible to utilize MVC 2 from MonoDevelop 2.2 (using Mono 2.4)? If so - is it as simple as grabbing a reference to the new System.Web.Mvc or is there something else to consider? I realize that any templating support in MonoDevelop may not be 100% there since it was built to utilize MVC v1 (at least as of MonoDevelop 2.2). If anyone can add any other tips or tricks that would help as well.

  • ASP.NET MVC2 - Resolve Parameter Attribute in Model Binder

    - by Nathan Taylor
    Given an action like: public ActionResult DoStuff([CustomAttribute("foo")]string value) { // ... } Is there any way to resolve the instance of value's CustomAttribute within a ModelBinder? I was looking at the MVC sources and chances are I'm just doing it wrong, but when I tried to replicate their code which retrieves the BindAttribute for a complex model, calling GetAttributes() did not return the attribute I am looking for. DefaultModelBinder GetTypeDescriptor(controllerContext, bindingContext).GetAttributes();

  • ASP.NET MVC Data passing

    - by user295541
    Hi, I need a good example or guideline which could give me a pattern for data passing between view and partial view. For example I have a view which contains several partial views. I refresh these partial view by ajax. So I need to pass data among view and its partial views. The best way would be if I could pass data without using Temp data dictionary. Anybody know a good article about this? l.

  • Realtime progress of AJAX call (asp.net)

    - by Dynde
    Hi... I'm trying to make a progress bar that updates the user on the progress of the AJAX call. My immediate thinking was that I need an AJAX call to start a thread on the server, allowing the starting AJAX call to finish, and allowing the thread to send updates back to the user. For the purpose of simplicity, disregard the actual progress bar functionality (I was thinking of implementing one of those JS bars, with fancy colors and effects ;), but if I can get an update from the thread, then updating a simple JS progress bar becomes trivial ;) ) I just need a few pointers on how to accomplish this, if anyone could oblige me? ;)

  • How to get all active parameters in ASP.NET MVC (2)

    - by SztupY
    Hi! I was wondering whether there is a way to create an ActionLink or similar, that changes only a few parameters of the actual query, and keeps all the other parameters intact. For example if I'm on an URL like http://example.com/Posts/Index?Page=5&OrderBy=Name&OrderDesc=True I want to change only the Page, or OrderBy parameter and keep all other parameters the same, even those I don't yet know of (like when I want to add a Search parameter or something similar too). The header of my current action looks like this: public ActionResult Index(int? Page, string OrderBy, bool? Desc) and I'm only interested in the values that this controller "eats". I want however that when I extend this action (for example with a string Search parameter) the links should work the same way as before. Here is what I did already: Create a new RouteValueDictionary and fill it with everything from RouteData.Values Problem: This only fills the parameters that are used in the Routing, so all other optional parameters (like Page) to the controller are lost Add everything from HttpContext.Request.QueryString to the previous dictionary This is what I am currently using Problem: It might have some junk stuff, that the Controller didn`t ask for, and it doesn't work if the page was loaded using POST. You also don't have any ModelBindings (but this isn't much of a problem, because we are re-sending everything anyway) Use HttpContext.Request.Params Problem: this has too much junk data which imho one shouldn't add to a RouteValueDictionary that is passed to an ActionLink So the questions: Is there an RVD that has all the data that was passed to the Controller and was used by it? Is this solution good, or are there any caveats I didn't think about (mainly in the context of changing a few query parameters while keeping the others intact)? Is there a way to filter out the "junk" data from the Params object?

  • How to test views in ASP.NET MVC2 (ala RSpec)

    - by Dmitriy Nagirnyak
    Hi, I am really missing heavily the ability to test Views independently of controllers. The way RSpec allows to do it. What I want to do is to perform assertions on the rendered view (where no controller is involved!). In order to do so I should provide required Model, ViewData and maybe some details from HttpContextBase (when will we get rid of HttpContext!). So far I have not found anything that allows doing it. Also it might heavily depend on the ViewEngine being used. List of things that views might contain are: Partial views (may be nested deeply). Master pages (or similar in other view engines). Html helpers generating links and other elements. Generally almost anything in a range of common sense :) . Also please note that I am not talking about client-side testing and thus Selenium is just not related to it at all. It is just plain .NET testing. So are there any options to actually do the testing of views? Thanks, Dmitriy.

  • Asp.Net MVC - Blank model not returning blank data

    - by Pino
    I have a form which a user can fill in x times with the data they want too. The form is posted to the following Action. [HttpPost] public ActionResult Manage(ProductOptionModel DataToAdd) { if (!ModelState.IsValid) { return View(DataToAdd); } var ProdServ = new ProductService(); if (DataToAdd.ID != 0) { //Edit Mode. DataToAdd = ProdServ.EditProductOption(DataToAdd); ViewData["Message"] = "Option Changes Made"; }else { //Add DataToAdd = ProdServ.AddProductOption(DataToAdd); ViewData["Message"] = "New Option Added"; } var RetModel = new ProductOptionModel() {ProductID = DataToAdd.ProductID}; return View(RetModel); } So at the bottom I blank the model (Leaving just the required field) and then return to the view. However the view holds the data from the previously submitted form. Any ideas why? I have debugged the code and checked that the RetModel variable is empty.
