问题 I have the following model: public class Person { public string Name { get; set; } public string Gender { get; set; } } I want the default gender to be female, so I set that up in the action: public ActionResult Create() { var model = new Person { Gender = "F" }; // default is female return View(model); } Finally, the view renders everything like this: @model Person @using (Html.BeginForm()) { @Html.EditorForModel() <p><input type="submit" value="Create" /></p> } This all works as expected.

问题 I know you can do this: #if !DEBUG [RequireHttps] //apply to this action only #endif What if you are using Web Farm Framework where "the Controller" server receives an outside SSL 443 request, decrypts it, then forwards it to the Primary / Secondary servers using http 80 (without ssl?) In this environment, I tried the [RequireHttps] attribute but it responded with "The page isn't redirecting properly" in Firefox. Firefox has detected that the server is redirecting the request for this address

问题 Question: I'm asking myself whether I should use .resx files or a database to localize my ASP.NET MVC 3 application. I use a database anyway, so there's no additional effort required for a data-access layer. I know I can do both, but I'm a bit worried about performance...

Also, it seems to me that the .resx-file way

问题 Using MVC3 I have found that setting a SelectList's selected value correctly renders the view on an HttpGet, but fails to render correctly on HttpPost. I have inspected the Model before they are forwarded to the View on HttpPost and they are correctly being updated, it just seems the View is not rendering the selected tag correctly. On HttpPost, the <select> is rendered exactly as it existed after any edits but before submission of the form. The m.SelectedWidgetId = 2; in the HttpPost method

Seem to me that for some reason that session is destroyed. Any

问题 I think I have a very noob question but there it is: I have a link to another controller and I want to pass a list of strings. Controller: [HttpPost] public ActionResult Index(DateTime? dateFilter, int? Provider, int? middleOffice) { ...

问题 I am implementing a fix for the problem caused by 02 compression issues over 3G. Web site exhibits JavaScript error on iPad / iPhone under 3G but not under WiFi The best solution seems to be http://stuartroebuck.blogspot.com/2010/08/official-way-to-bypassing-data.html which is basically to add the header Cache-Control: no-transform in IIS, however I would like to apply this only to specific file types.
