Hi, I've been looking for quite some time for a complete solution to uploading files in ajax for my site. For those of you who don't know, browsers won't let you upload files without making a full page reload. I haven't been able to find a good, working and cross browser solution for this problem. So after much research and development I have finally managed to solve this problem. Lets take a look at the following controller. public class HomeController : Controller { public ActionResult Index() { return View(); } [HttpPost] public ActionResult UploadImage(HttpPostedFileBase image) { try { if (Request.ContentLength > 1024 * 1024 * 2) { return UploadCompanyLogoResult(new { success = false, error = "File size too big. Maximum file size is 2MB." }); } if (Request.Files.Count == 0) { return UploadCompanyLog...

Hey, Lately I've been building many infrastructures for my company's website and I wanted to expose those infrastructures in the most natural way that coders are used to. One of the problems I spent time on was exposing the infrastructures on *.cshtml files. I didn't want to use static classes - because it's not a natural way, and not very trivial. So I managed to extend the class that represents the view, and by that add more properties and functions to it. public abstract class ViewBase<TModel> : WebViewPage<TModel> where TModel : class { public LayoutConfiguration LayoutConfiguration { get; private set; } public ViewBase() { LayoutConfiguration = LayoutConfiguration.GetInstance(); } public void DoWork() { } } And now on your Web.config (in the Views folder) replace this line: <pages pageBaseType="System.Web.Mvc.WebViewPage"> With this one: <pages pageBaseType="namespace.ViewBase...

Hey all, Few days ago I was challenged by a good friend and colleague to write a generic model binder for a dynamic json. Why does he need such a thing ? I'll explain: Normally, when you write a classic website using any platform, the contract between the client and the server is obvious and well known. However, if you write a complex web system, and you have the need to build your client model dynamically without creating a massive model on the server that handles all kinds of properties and values, you might be interested in getting a generic dictionary that contains all your client values. To implement it I used a state machine to parse the json: public class DictionaryModelBinder : DefaultModelBinder { private const string _dateTimeFormat = "dd/MM/yyyy HH:mm:ss"; private enum StateMachine { NewSection, Key, Delimiter, Value, ValueArray } public override object BindModel(ControllerContext controllerC...

Hey, Have you ever wanted to test your controller actions with the logic you add with ActionFilterAttributes? Well, I did. So I wrote this helper class, which executes the ActionFilterAttribute methods. public class FilterAttributeTester { public ActionExecutingContext ExecuteOnActionExecuting<TAttribute>(Controller aController, Func<ActionResult> aAction) where TAttribute : ActionFilterAttribute { var actionExecutingContext = CreateActionExecutingContext(aController, aAction); var attribute = GetAttribute<TAttribute>(aAction); attribute.OnActionExecuting(actionExecutingContext); return actionExecutingContext; } public ActionExecutedContext ExecuteOnActionExecuted<TAttribute>(Controller aController, Func<ActionResult> aAction) where TAttribute : ActionFilterAttribute { var actionExecutedContext = CreateActionExecutedContext(aController, aAction); var attribute = GetAttri...

Hey, I wanted to be able to create partial views in asp .net mvc in a way that every partial will declare its own styles and scripts. So the naive solution is to define a section in the layout, and in the partial view just put everything inside. The problem is, it's working only for one level deep. What happens if your partial view uses another partial views ? What happens if your layout is dynamic, and uses partial views as well? So I created the following solution: public class DynamicHeaderHandler : ActionFilterAttribute { private static readonly byte[] _headClosingTagBuffer = Encoding.UTF8.GetBytes("</head>"); private static readonly byte[] _placeholderBuffer = Encoding.UTF8.GetBytes(DynamicHeader.SectionPlaceholder); public override void OnActionExecuted(ActionExecutedContext filterContext) { if (filterContext.Result is ViewResult) { filterContext.HttpContext.Response.Filter = new ResponseFilter(filterContext...
