Given an HttpContext (or HttpContextBase), is there a way to get an instance of the Controller? The HttpContext will hold a reference to the MvcHandler , which will hold a reference to the RouteData , which will hold a reference to what controller is being invoked by a particular route. NB: This doesn't give you the actual controller, only the controller that the specific route is going to catch. GetController(HttpContextBase httpContext) { var routeData = ((MvcHandler)httpContext.Handler).RequestContext.RouteData; var routeValues = routeData.Values; var matchedRouteBase = routeData.Route; var

A common scenario I encounter is providing notifications / confirmations to users after they have performed an action to inform them of success. For example, suppose a user provides feedback on a feedback form and then clicks Submit Feedback . You may want to display a 'Thanks for your Feedback' message after you have performed some validation e.g. they have a valid email in the database. Some pseudocode: public ActionResult SubmitFeedback(string Feedback, int UserID) { MyDataContext db = new DataContext() if(db.usp_HasValidEmail(UserID)) //Check user has provided a valid email return View(

I am building a custom HTML.LabelFor helper that looks like this : public static MvcHtmlString LabelFor<TModel, TValue>(this HtmlHelper<TModel> self, Expression<Func<TModel, TValue>> expression, Boolean showToolTip) { var metadata = ModelMetadata.FromLambdaExpression(expression, self.ViewData); ... } To be able to get the proper name for the property I am using the following code : metadata.DisplayName And on the property of the ModelView class I got : [DisplayName("Titel")] The problem is that I also need a description. There is an Attribute called Display and that has Name and Description

I got a problem migrating from VS.Net 2008 / MVC 1 to VS.NET 2010 (+C# 4.0) / MVC 2 The web.config has been updated , the site runs well in Cassini, but my problem now is deploying on IIS 6. I updated the web site to run using ASP.Net 4 , but whatever URL I try, I always have a 404 error. It's as if the routing was not taken into account (yes, the wildcard mapping has been done). I do not understand this mess and could not google anything interesting... Thanks for your suggestions ! Ok I got y answer (thanks to a colleague) When migrating from ASP.Net 2.0 to ASP.Net4.0, if you meet the same

I have implemented an ajax-polling script that calls an action in the server Controller every 10 seconds. With the response, I replace the content of a div : function getFoo() { var link = '/Secure/GetFoo'; $.post(link, function (response) { $('#FooSection').replaceWith(response); }); setTimeout("getFoo();", 10000); } This is done through https . After some time of being "idle", IE displays the following message: This page is accessing information that is not under its control. This poses a security risk. Do you want to continue? If the user clicks Yes , the page is redirected to the div

Currently using the below code to create a string array (elements) that contains all string values from Request.Form.GetValues("ElementIdName"), the problem is that in order for this to work all my dropdown lists in my View have to have the same element ID name which I don't want them to for obvious reasons. So I am wondering if there's any way for me to get all the string values from Request.Form without explicitly specifying the element name. Ideally I would want to get all dropdown list values only, I am not too hot in C# but isn't there some way to get all element ID's starting with say
