问题 In our current ASP.Net Webforms application we have several composite/template server controls that only exist for a common look and feel. For example, we have a panel control that has a title, a place for buttons related to the contents of the panel, and of course the contents. How is this best accomplished in MVC? RenderPartial doesn't get done what I need here. Should I still be using the same controls, but just on a view page? These controls don't really do anything on postback, they are

问题 I have a Controller. "OrderController". Currently it's 1800 lines. I like to reduce the size. I'm using static helper methods which is fine but i'm using ninject to call my repositories so don't have access to the repositories in the static methods without passing the properties in.

问题 I have a large web application that I have set up as both ASP.Net Web Forms and MVC. Some of the newer pages are MVC (.mvc) and some are Web Forms (.aspx). Since this is a business app and functions are being constantly added, it's hard for me to have the time to stop and replace existing functionality to convert it over. So I would like to do it piece by piece, control by control. To do this, all I would need to be able to do is to replace certain controls with <% Html.RenderPartial() %> or

问题 So I know that EF entities track their own changes and persist them to the database when savechanges is called, but what about this scenario... I have a page that is designed to edit a blog post. It has two action methods. [HttpGet] public ViewResult EditBlogPost(int Id) { //This action method gets the blog post by the id and returns the edit blog post page. BlogPost blogPost = db.BlogPosts.Where(x => x.Id == Id).FirstOrDefault(); if (blogPost == null) { ViewData["message"] = "Blog post not

问题 I'm considering re-rewriting some of my MVC controllers to be async controllers. I have working unit tests for these controllers, but I'm trying to understand how to maintain them in an async controller environment. For example, currently I have an action like this: public ContentResult Transaction() { do stuff... return Content("result"); } and my unit test basically looks like: var result = controller.Transaction(); Assert.AreEqual("result", result.Content); Ok, that's easy enough. But when

问题 How do I store a variable or object application wide in ASP.net MVC? In regular ASP, you had the Application object and in ASP.net too apparently.

问题 I would like to have custom error pages unique to an MVC area. Unfortunately, it appears that the Web.config override system doesn't take the MVC folder structure into account. If I want to override an area called "mobile", I have to create a root project folder (in with Views and Controllers) named "mobile" and put the Web.config in there with the new customErrors element. Is there some better way to do this so that I don't have to create a root folder for any overrides? 回答1: I've been

问题 I am using automapper to map my models to viewmodel classes to pass to my view. My question really is where should the validation go? I was planning on using the MetaData decorations - a feature of mvc 2. But either in the model or viewmodel? Or in both places? 回答1: Validation should be done minimum at the View Model because this is what you receive as action argument and contains the user input. You could also have validation at the model. 回答2: My answer would be ViewModel because Model can
