问题 I have a controller that stores various info (Ie. FormID, QuestionAnswerList, etc). Currently I am storing them in the Controller.Session and it works fine. I wanted to break out some logic into a separate class (Ie. RulesController), where I could perform certain checks, etc, but when I try and reference the Session there, it is null. It's clear that the Session remains valid only within the context of the specific controller, but what is everyone doing regarding this? I would imagine this

问题 I know I've had a ton of questions today, but still trying to get everything under control learning MVC 2 tie right way.

问题 We have a lot of domains running on one IIS WebSite/AppPool. Right now we are in the process of implementing SSO with Windows Identity Foundation. in web.config the realm has to be set with <wsFederation passiveRedirectEnabled="true" issuer="http://issuer.com" realm="http://realm.com" requireHttps="false" /> My problem is that the realm is dependent on which domain the user accessed the website on so what I did is that I set it in an global action filter like this var module = context

问题 Is it possible to create Ajax.ActionLink which has instead of text, the whole DIV? I'd like to map div on Ajax.ActionLink 回答1: I don't think that this will work using the standard MVC Ajax scripts. I believe that the MVC javascript is created to use an <a> element by default.

As an example: <div onclick="SomeAjaxFunction()">some div

问题 What is the most straight forward way to use AuthorizeAttribute and JsonResult together so that when the user is not authorized the application returns a Json error rather than a log in page? The two things I am currently considering are extending AuthorizeAttribute or just making a new attribute that implements IAuthorizationFilter . 回答1: Remove the AuthorizeAttribute from your Action. Then in the first lines of your action, insert this: if (!User.Identity.IsAuthenticated) return Json("Need

问题 I'm using asp.net mvc 2 with C# and DataAnnotations. The situation is this: I have a custom control that is strongly typed against a model class. This control is displayed on the view several times but with differing property values, such as headings (Ex: Question 1, Question 2, Question 3, etc.. are all headings). I can write a custom validation class that validates this object as a whole, but the problem is, I can't get specific Html.ValidationMessage(...) tags to display. The validation
