问题 We recently updated our solution to MVC 2, and this has updated the way that the AntiForgeryToken works. Unfortunately this does not fit with our AJAX framework any more.

问题 For some reason, when certain bots visit the site, generating a url with the UrlHelper.Action method raises a null exception from System.Web.HttpServerVarsCollection.Get . I've done some debugging and the call stack originiates with an attempt to get the 'HTTP_X_ORIGINAL_URL' from the HttpContextBase.Request.ServerVariables collection. If I visit the same address directly from a browser - no problem. The page is server and no error is logged. It only seems to occur when visited by a bot. Not

问题 I'm trying to call an action method in an MVC application using jQuery. Basically what I want is to take the value of a couple of input fields and call the action method by clicking a button, passing the values of the input fields as parameters. But I only get the value of the "number" parameter, not the "year" parameter. function selectWeek() { $('#selectWeekButton').click(function (event) { var number = $("#selectWeekId").val(); var year = $("#selectYearId").val(); var actionUrl = '<%: Url

问题 I have the following <label for="Forename">Forename</label> <%= Html.TextBoxFor(m => m.Customer.Name.Forename) %> the problem with this is that this is rendered as <label for="Forename">Forename</label> <input type="text" value="" name="Customer.Name.Forename" id="Customer_Name_Forename"> not what I want ofc.

问题 I have an ASP.NET MVC 2 application. Web project contains a reference to SomeProject SomeProject contains references to ExternalAssembly1 and ExternalAssembly2. SomeProject explicitly calls into ExternalAssembly1, but NOT ExternalAssembly2. ExternalAssembly1 calls into ExternalAssembly2 When I perform a local build everything is cool. All DLLs are included in the bin\debug folder. The problem is that when I use the Publish Web command in Visual Studio 2010, it deploys everything except

问题 I have an action method that I need to execute when the back button is clicked. I've done this before by disabling the cache in my action method (Response.Cache.SetCacheability(HttpCacheability.NoCache). This isn't working for a different action method.
