问题 For some reason my Visual Studio 2013 Preview cannot create MVC 5 Projects. Since the MVC project is now open source in CodePlex I was wondering if there's a simple way to develop MVC 5 projects in my Visual Studio 2012 Ultimate. 回答1: A new tutorial has been recently added to the ASP.NET website on how to upgrade an MVC4 project to MVC5.

问题 OK, I find it EXTREMELY ridiculous that I have to post a new question to find the answer but, alas here I am. Let's make this as simple as possible for the next wayward soul looking to resolve this. What are all the most current scripts I require to get the ajax form working? Thus far I have; <script src="//ajax.aspnetcdn.com/ajax/jQuery/jquery-1.11.0.js"></script> <script src="//ajax.aspnetcdn.com/ajax/jquery.ui/1.10.4/jquery-ui.min.js"></script> <script src="//ajax.aspnetcdn.com/ajax/jquery

问题 I've read this and while it explains how role changes will eventually propagate to the user cookie after some time interval, I still don't understand how I force an immediate change to user roles.

If I use AuthenticationManager.SignOut(); then I sign off myself (admin), not the user, whose roles I want to change. Currently I use await UserManager.UpdateSecurityStampAsync(user.Id); to generate a new

问题 How do I configure my mvc/webapi project so that a webapi method called from a razor view doesn't return the loginpage when its unauthorised? Its a MVC5 application which also has WebApi controllers for calls via javascript. The two methods below [Route("api/home/LatestProblems")] [HttpGet()] public List<vmLatestProblems> LatestProblems() { // Something here } [Route("api/home/myLatestProblems")] [HttpGet()] [Authorize(Roles = "Member")] public List<vmLatestProblems> mylatestproblems() { //

问题 This question already has answers here : How does MVC 4 List Model Binding work? (5 answers) Closed 4 years ago . I have a list of items that will be associated to a user.

I want to create checkboxes from these. I then want to send the selected ones back into the controller to be associated

问题 I'm using MVC 5, C# and I'm trying to build a search filter that will filter through upon each key stroke. It works as so, but the textbox erases after submitting. Now this is probably not the best approach to it either. Is there a way to make so when it posts it doesn't erase the textbox, or better yet, is there a better alternative? @using (Html.BeginForm("Index", "Directory", FormMethod.Post, new { id = "form" })) { <p> Search Employee: <input type="text" name="userName" onkeyup=
