model-binding

Is there any way of changing the binding prefix with a value which comes from the request parameters? I have many nested search popups, and all of them shares the same ViewModel. I can add a binding prefix to all the fields when requesting for the Search filters, but i don't know how can i make the [Bind(Prefix = "")] to work with values coming from the request parameters. // get the search filters with the bindingPrefix we need public ActionResult Search(string bindingPrefix) { ViewData.TemplateInfo.HtmlFieldPrefix = bindingPrefix; SearchViewModel model = new SearchViewModel { BindingPrefix =

In my controller I have: [AcceptVerbs("GET", "POST")] public List<BuzzMonitor.Web.Message> Search(string text, DateTime dateFrom, DateTime dateTo, List<int> themeIds, List<int> sourceIds) {...} and I want to do model binding. It's easy for primitive types, but what to do when I have a list of primitive types? I did it like this in Global.asax: GlobalConfiguration.Configuration.Routes.MapHttpRoute("SearchWithParameters", "api/{controller}/{action}/{text}/{dateFrom}/{dateTo}/?/?" But I dont know what to set for lists... I found on some site that I can add [ModelBinder] before list, but when I do

Related question: Web API ApiController PUT and POST methods receive null parameters intermittently Background While load testing an existing Web API project I noticed a lot of null reference exceptions as a result of a parameter being null when posting to an action. The cause seems to be a custom message handler registered to log requests while running in dev environments. Removing this handler resolves the issue. I understand that in Web API I can only read the request body once and that reading it would always cause my parameter to be null as model binding wouldn't be able to take place.

Is there any useful hook in ASP.NET MVC (MVC4) which can let you access the Action method parameter (View model) before the action method becomes invoked, and then also (e.g. depending on the value of something you checked in the action method parameter) let you prevent the action method from being invoked, i.e. instead either forward the view model object (action method parameter) to another action method or directly to some view (i.e. without any further processing in an action method) ? If you do not understand the question, please see the code example below which should illustrate the kind

This problem has been driving me crazy for several hours now... In my domain, I have 2 entities that are related to each other Sku and Item . Each sku can have many items. public class Sku { private readonly EntitySet<Item> items; public Sku() { items = new EntitySet<Item>(AttachItems, DetachItems); } public int SkuId { get; set; } public string LongDescription { get; set; } public EntitySet<Item> Items { get { return items; } set{ items.Assign(value);} } private void AttachItems(Item entity) { entity.Sku = this; } private static void DetachItems(Item entity) { entity.Sku = null; } } public

I'm using KendoUI Grid to show data. I have server paging working like a charm. The each page change in the kendo grid is a new ajax request to the server and the server returns the correct page of data. I am now trying to do server-side sorting, but I'm having trouble getting model binding to bind to the sort values. This is what the request from the Kendo Grid looks like: My action method looks like this: public JsonResult GetReports(int pageSize, int skip, List<KendoSort> sort) { // sort is not being populated with the right data. } KendoSort is a custom class: public class KendoSort {

There seems to be an issue with the ViewBag dynamic properties. Lets say I have: @{ ViewBag.Title = @Model.CourseName; } And then in a form on the page I have: @Html.TextBox("Title", null, new {style="width:400px;"}) Where Title is the name of a field in a database table. When the page first opens, text box with an id of "Title" takes the value of the ViewBag.Title dynamic property. I am a bit hazy on the exact details of Model Binding, but this does seem to be a bug, or if not, if it is something that occurs naturally as a result of the binding process, then it would be nice to be warned of

I currently have a ViewModel setup as such: public class OurViewModel { public OurViewModel() { } [Required] public int LeadID { get; set; } [Required] public int Rate { get; set; } [Required] public bool DepositRequired { get; set; } [RequiredIfOtherPropertyIsTrue("DepositRequired")] public BankInfo { get; set; } } ...in this case, "RequiredIfOtherPropertyIsTrue" is a validator that does pretty much what it says: checks to see if another property is true (in this case, our boolean indicating whether or not a deposit is required), and BankInfo is another model that looks something like this:
