  • Will the URL /nosuchpage get routed via my ASP.NET MVC application?

    - by Gary McGill
    [I'm trying to figure out the reason why I'm having another problem, and this question is part of the puzzle.] I have an MVC 2 website that has routing set up so that URLs such as /Customer/23/Order/47 get handled by various controllers. I do not have a rule that would match, for example, /nosuchpage and in my Cassini environment a request for that URL will trigger my Application_Error code, which lets me log the error and show a friendly response. However, when I deployed this website on IIS7 using integrated mode, my Application_Error is not triggered, and IIS shows its own 404 message. No matter what I've tried, I can't get Application_Error to fire. Now I'm thinking: is the reason it doesn't fire because the request is not getting routed via my application? Either because I didn't explicitly set up a catch-all route, or because the file-extension fools it into thinking it should use the "static file handler" (whatever that is)? Should I expect my Application_Error to be invoked?

  • Update image in ASP.NET page from memory without refreshing the page.

    - by ZeeMan
    I have a command line C# server and an ASP.NET client, they both communicate via .NET Remoting. The server is sending the client still images grabbed from a webcam at say 2 frames a second. I can pass the images down to the client via a remote method call and the image ends up in this client method: public void Update(System.Drawing.Image currentFrame) { // I need to display the currentFrame on my page. } How do i display the image on the a page without saving the image to the hard disc? If it was a winForms app i could pass currentFrame to a picturebox ie. picturebox.Image = currentFrame. The above Update method gets fired at least 2 times a second. If the client was a winForms app i could simply put picturebox.Image = currentFrame and the current frame on the screen would automatically get updated. How do i achieve the same effect with ASP.NET? Will the whole page need to be reloaded etc?

  • where should I put the EF entity and data annotations in asp.net mvc + entity framework project

    - by giddy
    So I have a DataEntity class generated by EntityFramework4 for my sqlexpress08 database. This data context is exposed via a WCF Data Service/Odata to silverlight and win forms clients. Should the data entities + edmx file (generated by EF4) go in a separate class library? The problem here then is I would specify data annotations for a few entities and then some of them would require specific MVC attributes (like CompareAttribute) so the class library would also reference mvc dlls. There also happen to be entity users which will be encapsulated or wrapped into an IIdentity in the website. So its pretty tied to the mvc website. Or Should it maybe go in a Base folder in the mvc project itself? Mostly the website is data driven around the database, like approve users, change global settings etc. The real business happens in the silverlight and win forms apps. Im using mvc3 rc2 with Razor. Thanks

  • How to create a RESTful web service in asp.net?

    - by jonhobbs
    Hi Guys, I simply want to create a fairly basic REST service, so that I can expose some of the data in my asp.net/SQL server application to the outside works, like this..... http://domain.com/api/offices - would return an xml set of office locations. http://domain.com/api/offices/15 - would return all the details of office 15. It's all fairly standard stuff (including basic authentication) but there seem to be several ways to achieve this using Microsoft technologies and I don't really know where to start. These seem to be the options... 1) WCF 2) ASP.NET MVC 3) ADO.NET Data Services 4) Rest Starter Kit project templates? Which of these is the easiest and most "up-to-date" solution to creating a web service?

    - by m0s
    If I want to create a button control like that, is it supposed to be a User Control or a Custom Control? I am not sure maybe something else? Ideally I want to be able style/animate the main button and the inner button separately; also obviously Ill need to process their events separately. These buttons will be created at run-time and Ill need to set the icons dynamically.

  • ASP.NET mvc 2 Validation always shows errors on initial page load.

    - by gt124
    I've searched around a lot, and honed this problem down to this case: I'm using the PRG pattern, pragmatically I'm using the same DTO for my post/get actions. It looks like when I have the dto with the data annotation attributes in the get action parameter list, the validation is always displaying errors, every time on initial page load. In some cases this could be desired behavior if you put asterisks in the error message, but how do I get rid of it? Thanks in advance.

  • ASP.NET MVC - Form Post always redirect when I just want to bind json result to a div

    - by Saxman
    Hi all, I'm having a little problem with json result. I'm submitting a contact form, and after the submission, I just want to return some json data (indicating either a success or failed and displays a message) back to the view, without causing a redirect, but it kept redirecting me to the action, here are the codes: HTML <div id="contactForm2" class="grid_6"> <div id="contactFormContainer"> @using (Html.BeginForm(MVC.Home.ActionNames.ContactForm, MVC.Home.Name, FormMethod.Post, new { id = "contactForm" })) { <p> <input type="text" tabindex="1" size="22" value="" id="contactName" class="text_input required" name="contactName" /> <label for="contactName"> <strong class="leftSpace">Your Name (required)</strong></label></p> <p> <input type="text" tabindex="2" size="22" value="" id="contactEmail" class="text_input required" name="contactEmail" /> <label for="contactEmail"> <strong class="leftSpace">Email (required)</strong></label></p> <p> <input type="text" tabindex="2" size="22" value="" id="contactPhone" class="text_input" name="contactPhone" /> <label for="contactPhone"> <strong class="leftSpace">Phone</strong></label></p> <p> <label> <strong class="leftSpace n">Message (required)</strong></label> <textarea tabindex="4" rows="4" cols="56" id="contactMessage" class="text_area required" name="contactMessage"></textarea></p> <p> <input type="submit" value="Send" tabindex="5" id="contactSubmit" class="button submit" name="contactSubmit" /></p> } </div> <div id="contactFormStatus"> </div> </div> Controller [HttpPost] public virtual JsonResult ContactForm(FormCollection formCollection) { var name = formCollection["contactName"]; var email = formCollection["contactEmail"]; var phone = formCollection["contactPhone"]; var message = formCollection["contactMessage"]; if (string.IsNullOrEmpty(name) || string.IsNullOrEmpty(email) || string.IsNullOrEmpty(message)) { return Json(new { success = false, message = "Please complete all the required fields so that I can get back to you. Thanks." }); } // Insert contact form data here... return Json(new { success = true, message = "Your inquery has been sent. Thank you." }); } javascript $(document).ready(function () { $('#contactSubmit').live('click', function () { var form = $('#contactForm'); var formData = form.serialize(); $.post('/Home/ContactForm', formData, function (result) { var status = $('#contactFormStatus'); if (result.success) { $('#contactForm')[0].reset; } status.append(result.message); }, 'json' ); return false; }); }); I've also tried this javascript, but also got a redirect $(document).ready(function () { $('#contactSubmit').live('click', function () { var form = $('#contactForm'); var formData = form.serialize(); $.ajax({ type: 'POST', url: '/Home/ContactForm', data: formData, success: function (result) { SubmitContactResult(result); }, cache: false }); }); function SubmitContactResult(result) { var status = $('#contactFormStatus'); if (result.success) { $('#contactForm')[0].reset; } status.append(result.message); } }); Any idea what's going on with my code? Thank you very much.

  • Ajax Auto Complete in ASP.Net MVC project - How to display a an object's name but actually save it's

    - by Ben
    I have implemented the Ajax Autocomplete feature in my application using a web service file that querys my database and it works great. One problem I am having is allowing the user to see the item's name, as that's what they are typing in the textbox, but when they select it, it saves the item's ID number instead of the actual name. I want it to behave much like a dropdown list, where I can specify what is seen and entered vs. what is actually saved in the database (in this case, the product ID instead of it's name.) I have this text box in my view, along with the script: <script type="text/javascript"> Sys.Application.add_init(function() { $create( AjaxControlToolkit.AutoCompleteBehavior, { serviceMethod: 'ProductSearch', servicePath: '/ProductService.asmx', minimumPrefixLength: 1, completionSetCount: 10 }, null, null, $get('ProductID')) }); </script> <p> <label for="ProductID">Product:</label> <%= Html.TextBox("ProductID", Model.Products)%> <%= Html.ValidationMessage("ProductID", "*")%> </p> Here's what is in my asmx file: public class ProductService : System.Web.Services.WebService { [WebMethod] public string[] ProductSearch(string prefixText, int count) { MyDataContext db = new MyDataContext(); string[] products = (from product in db.Products where product.ProductName.StartsWith(prefixText) select product.ProductName).Take(count).ToArray(); return products; } } Can anyone help me figure this out? I'm using this so they can just start typing instead of having a dropdown list that's a mile long...

  • Create and Call an ASP.NET Asynchronous Web Service and call it from JavaScript

    - by nickyt
    Environment: ASP.NET web applicaition jQuery, ASP.NET AJAX Currently using ASP.NET Web Services The title says it all. One, how do i create an ASP.NET web service that is asynchronous? I've seen many articles, that show example with IAsyncResult and BeginMyWebServiceMethod and EndMyWebServiceMethod, some using ThreadPool etc. I would just like to know what is the simplest way to make an asynchronous web service method call (ideally without having to implement other classes, if possible). To me it should be as simple as adding an attribute to the method (but I think that is wishful thinking), e.g. public SomeWebService : WebService { [Asynchronous] public static bool SomeCheck() { // code } } I'm open to using WCF if that makes it easier (we converted to ASP.NET 3.5 around Christmas time). Once I have the asynchronous web service created, what is the best way to call it from client-side script? Via jQuery's $ajax or ASP.NET's auto generated class for a web service that is script method?

  • How to pass content in response from Exception filter in Asp.net WebAPI?

    - by jaffa
    Consider following code: My problem is: 1) I can't seem to cast the errors to HttpContent 2) I can't use the CreateContent extension method as this doesn't exist on the context.Response.Content.CreateContent public class ServiceLayerExceptionFilter : ExceptionFilterAttribute { public override void OnException(HttpActionExecutedContext context) { if (context.Response == null) { var exception = context.Exception as ModelValidationException; if ( exception != null ) { var modelState = new ModelStateDictionary(); modelState.AddModelError(exception.Key, exception.Description); var errors = modelState.SelectMany(x => x.Value.Errors).Select(x => x.ErrorMessage); // Cannot cast errors to HttpContent?? // var resp = new HttpResponseMessage(HttpStatusCode.BadRequest) {Content = errors}; // throw new HttpResponseException(resp); // Cannot create response from extension method?? //context.Response.Content.CreateContent } else { context.Response = new HttpResponseMessage(context.Exception.ConvertToHttpStatus()); } } base.OnException(context); } }

  • How to convert model into url properly in asp.net MVC?

    - by 4eburek
    From the SEO standpoint it is nice to see urls in format which explains what is located on a page Let's have a look on such situation (it is just example) We need to display page about some user and decided to have such url template for that page: /user/{UserId}/{UserCountry}/{UserLogin}. And create for this purpose such model public class UserUrlInfo{ public int UserId{get;set;} public string UserCountry{get;set;} public string UserLogin{get;set;} } I want to create controller method where I pass UserUrlInfo object but not all required fields. Classic controller method for url template shown above is following public ActionResult Index(int UserId, string UserCountry, string UserLogin){ return View(); } and we need to call it like that Html.ActionLink<UserController>(x=>Index(user.UserId, user.UserCountry, user.UserLogin), "See user page") I want to create such controller method public ActionResult Index(UserUrlInfo userInfo){ return View(); } and call it like that: Html.ActionLink<UserController>(x=>Index(user), "See user page") Actually I works when we add one more route and point it to the same controller method, so routing will be: /user/{userInfo} /user/{UserId}/{UserCountry}/{UserLogin} In this situation routing engine gets string method of our model (need to override it) and it works ALMOST always. But sometimes it fails and show url like /page/?userInfo=/US/John So my workaround does not always work properly. Does anybody know how to work with urls in such way?

  • msbuild for .NET 3.5 issue with csla and System.Linq

    - by Sash
    This is a weird problem. I am trying to build a .NET 3.5 solution with msbuild. I generally write custom build scripts for this, and when I tried this time to build a simple .NET assembly which internally uses CSLA, it started giving me Linq errors. However, if I build the proj file via msbuild (command line), it seems to build just fine. No issues at all. Anyone else encounter this issue...and if yes, how do i fix this? Thanks, Sashidhar Kokku

  • Multi-threaded library calls in ASP.NET page request.

    - by ProfK
    I have an ASP.NET app, very basic, but right now too much code to post if we're lucky and I don't have to. We have a class called ReportGenerator. On a button click, method GenerateReports is called. It makes an async call to InternalGenerateReports using ThreadPool.QueueUserWorkItem and returns, ending the ASP.NET response. It doesn't provide any completion callback or anything. InternalGenerateReports creates and maintains five threads in the threadpool, one report per thread, also using QueueUserWorkItem, by 'creating' five threads, also with and waiting until calls on all of them complete, in a loop. Each thread uses an ASP.NET ReportViewer control to render a report to HTML. That is, for 200 reports, InternalGenerateReports should create 5 threads 40 times. As threads complete, report data is queued, and when all five have completed, report data is flushed to disk. My biggest problems are that after running for just one report, the aspnet process is 'hung', and also that at around 200 reports, the app just hangs. I just simplified this code to run in a single thread, and this works fine. Before we get into details like my code, is there anything obvious in the above scendario that might be wrong?

  • Is it possible to use Dependency Injection/IoC on an ASP.NET MVC FilterAttribute ?

    - by Pure.Krome
    Hi folks, I've got a simple custom FilterAttribute which I use decorate various ActionMethods. eg. [AcceptVerbs(HttpVerbs.Get)] [MyCustomFilter] public ActionResult Bar(...) { ... } Now, I wish to add some logging to this CustomFilter Action .. so being a good boy, I'm using DI/IoC ... and as such wish to use this pattern for my custom FilterAttribute. So if i have the following... ILoggingService and wish to add this my custom FilterAttribute .. i'm not sure how. Like, it's easy for me to do the following... public class MyCustomFilterAttribute : FilterAttribute { public MyCustomFilterAttribute(ILoggingService loggingService) { ... } } But the compiler errors saying the attribute which decorates my ActionMethod (listed above...) requires 1 arg .. so i'm just not sure what to do :(
