问题 I have a ViewBag data from the controller that I get in the View . However, my view is made of multiple components and a component (Which is a html template and relevant JavaScript ), has a placeholder for this data where I need to display this data.

Please help me with a sample snippet 回答1: If I understood correctly you

问题 I have been assigned a task where I (the iDP) need to connect to a service provider. So far I have the code: public ActionResult SSO(string SAMLRequest) { var model = new ApiSsoModel(); try { if (SAMLRequest == null) throw new ArgumentNullException("The parameter \"SAMLRequest\" is null."); byte[] decoded2 = Convert.FromBase64String(SAMLRequest); string decoded3 = string.Empty; using (MemoryStream stream2 = new MemoryStream(decoded2)) { using (MemoryStream stream3 = new MemoryStream()) {

问题 I think I get the idea of the ViewModel in MVC but, when doing updates and deletes, it seems like there should be a distinct model for posting to the controller. I noticed the default razor controllers use ViewBag to hold Selectlists. I guess that makes the ViewModel (domain entities really) reusable on the return trip because it is stripped of unnecessary data. But it seems like resorting to ViewBag doesn't make sense when using view models because the view model can contain the Selectlist s

问题 Is it correct to use one view file with say 2 functions inside it. For example I have project table in my database and I have 2 functions inside the view file for this specific MySQL query.

The idea of MVC is to separate the Model, e.g. everything not related to presentation from the

问题 I'm new to Rails, and working my way through a couple of books, coding small test projects as I go. My latest dev app is a question and answer program. The idea is to have a database table full of questions. A user will bring up the web app and be presented with the first question. User enters answer into a form, and if it is correct, he gets the next question. Pretty simple. So, I've used generate scaffold to create a questions table and a users table. This works well - I can navigate to the

问题 I have serious problem I can not pass my data to controller when the form submitted how I can solve this ? //int controller class [HttpPost] public ActionResult Index(EnterpriseFramework.Entity.Synchronization.BindableEntity model) { //do something } and my view : @model EnterpriseFramework.Entity.Synchronization.BindableEntity <p> @using (Html.BeginForm()) { <fieldset> <legend>title</legend> <div> @Html.HiddenFor(m => (m.Underlay.Entity as AutomationTest.Models.DTO.Letter).oau_Letter_Id) <

问题 I'm developing a basic web app using the MVC architecture. I'm building my own to try and fully understand how the MVC arch works so this doubles as a learning exercise. I am using the Aura Router classes to map my URLs to controllers and action so that something like mysite.com/login will be mapped to LoginController and if I submit a form to mysite.com/login/login it will map it to LoginController->doAction('login'). Example of a controller looks like this: class LoginController implements

问题 I'm not able to understand why my simple configuration of DispatcherServlet to implement Spring MVC does not work.
