问题 I have a scenario where I have a login form next to a registration form, as the login form is a permanent fixture (until much further development), and sometimes registration as the main content coincides with this login form. Now we enter the twilight zone: Both forms have different actions on different controllers, but they share two things in common, being they both have a ValidationSummary , and they both have a field called UserName . If I cause a server side validation error, e.g. when

问题 I'm trying to use jQuery Datatables 1.10 with server side processing and ASP.NET MVC 5. Unfortunately, Datatables 1.10 writes to the server by serializing a complex hierarchy of objects into a param string ( Content-Type: application/x-www-form-urlencoded ), which breaks the MVC ModelBinder. Is there any way, in MVC, to bind a complex hierarchy of objects passes as a serialized parameter list? Perhaps a custom ModelBinder that someone has written? Note: Setting traditional = true in the ajax

问题 I am setting up an end-point using ASP.NET MVC to which requests can be made to manipulate and retrieve data (basically, an API). I am using a 2-legged OAuth model to validate that requests be signed using a secret key and signing method as well as a nonce table to prevent hi-jacking. Since Model Binding is so handy in ASP.NET MVC I am going to take advantage of it to consume requests, but I wonder if I can bake the signature verification and nonce/timestamp handling right into the model

问题 I have an Asp.net MVC app that currently works well using the default model binder and urls with complex parameters like this: example.com/Controller/Action?a=hello&b=world&c=1&d=2&e=3 (notice the question mark) The different urls automatically map to Action Method parameters using the built in model binder. I would like to continue using the standard model binder but I need to get rid of the query string. We want to put these urls behind a CDN that does not support resources that vary by

问题 I have a strongly typed view with my viewmodel which contains an object Person and an List of Skills. Person is quite straightforward. I use Html Helpers like this @Html.TextBoxFor(m => m.Person.FirstName) . I submit my form and get what I want. The problem is my List of skills. With an AJAX call i get a JSON result which is an array of Skills. How should I send the combination of both the skills and the person to my HTTPPOST method? I see two possibilities. The one I favour, but have no idea

问题 Quick question regarding updating a list of items in asp.net mvc. Basically I have an edit action method that returns a collection of objects (incidentally, the table structure of which looks as follows 'testID, assetID, Result' - a link table). I basically want this items to be displayed one after another in a form and to be able to edit them. The form should post back and the modelbinder do its magic. But, its not that easy.
