model-binding

问题 Say I have a Dictionary<string, string> and I want to update an object with the values from the dictionary, just like model binding in MVC... how would you do that without MVC? 回答1: You could use the DefaultModelBinder to achieve this but you will need to reference the System.Web.Mvc assembly to your project. Here's an example: using System; using System.Collections.Generic; using System.ComponentModel.DataAnnotations; using System.Globalization; using System.Linq; using System.Web.Mvc;

问题 I was under the impression that when binding to a complex model, all public properties were processed and a match binding attempted for each. I'm trying to resolve a variable naming problem so that a model class Model { public string Foo {get;set;} public string FooBar {get;set;} } works nicely with a query string like ?foo=foo&foo_bar=foo_bar Is there a better way than with a custom model binder? In any case, mine doesn't work. FooBar is simply skipped. public class StringModelBinder :

问题 Preamble My use-case includes a front-end WYSIWYG editor. Taking user input in HTML5/CSS format from the CSHTML Front-End View. Receiving the input in the Backend Controller's action via POST request. And finally doing fancy Database stuff with it. Sounds pretty easy. Using this beast of an editor, it's very straightforward and customizable. View WYSIWYG editor textarea nested within a form to send editor's raw HTML data using POST <form class="form" asp-controller="CreationController" asp

问题 I could not bind the model to Controller. Please give me any advice. Model,controller and view classes are below. When model is submmited, dictionary property equals to null. public class GroupRights //model { public List<DtoGrup> groups { get; set; } public Dictionary<short, Dictionary<EnFunction, bool>> groupRights { get; set; } // group function HasPermission } public enum EnFunction { LPDU_login, LPDU_changePassword, LPDU_transitList, LPDU_PosEventList, .... } Controller public

问题 I'm using the new WebApi which is part of MVC4 beta. I have the following class: public class Voucher { public string Id { get; set; } public string TableId { get; set; } public Product[] Products { get; set; } } My controller looks like this: public class VouchersController : ApiController { public Voucher PostVoucher(Voucher voucher) { //.... } } On the client side I serialize the data using an XmlSerializer . The output looks like expected and the Products array is serialized. If I post

问题 I've found a lot of information on implementing a custom model binder for validation purposes but I haven't seen much about what I'm attempting to do. I want to be able to manipulate the values that the model binder is going to set based on attributes on the property in the view model. For instance: public class FooViewModel : ViewModel { [AddBar] public string Name { get; set; } } AddBar is just public class AddBarAttribute : System.Attribute { } I've not been able to find a clean way to

问题 I'm fairly new to ASP.NET MVC and am trying to work out the best way to do this. It's probably simple but I just want to do things correctly so I thought I'd ask. Lets say I have a model that is this: Task - Id, Description, AssignedStaffMember StaffMember - Id, FirstName, LastName and in my view I want to create a new task. I make a strongly typed Razor view, and can use EditorFor to create textboxes for Description but what about AssignedStaffMember? I want a drop down list of all current

问题 I have an object containing searching, sorting and paging parameters as well as an id of a record to be edited. I'd like to pass this object into Html.ActionLink() as a route value object, so that the resulting query string will be correctly mapped by the default model binder into the Edit action's parameter, which is an EditViewModel. The idea is that after the Edit action completes, it can redirect back to the Index and maintain the same paging/sorting position, in the same data set, and
