modelbinders

问题 I am using a custom ModelBinder in an MVC 4 application, but it is invoked on a different thread than the request event handlers in global.asax, and this makes setting up a performance profiling context in a ThreadLocal fail. The threadId is in brackets at the start of each line, and you can see that the thread changes when the model binding is invoked, and that is the thread in which the controller action (Index) is executed. [33] | ERROR | MyApp.MvcApplication | Application_BeginRequest [33

问题 I want to set ModelBinders.Binders.DefaultBinder=new SmartBinder() in asp.net mvc 4 using autofac, what is the right way to do that? 回答1: In your Global.asax.cs; protected void Application_Start() { System.Web.Mvc.ModelBinders.Binders.DefaultBinder = new SmartBinder(); } Autofac is not needed to do that. 来源： https://stackoverflow.com/questions/18286948/how-to-set-defaultbinder-modelbinders-binders-defaultbinder-in-asp-net-mvc-4-usi

问题 I have a complex form It allows the user to create an IncomeDeclaration which has many Activities. This works fine when the markup for the Activities is like this: <tr> <td>SomeActivity <input type="hidden" value="13123" name="EconomicActivityIncomeDeclarations[0].EconomicActivityId" id="EconomicActivityIncomeDeclarations_0__EconomicActivityId"> </td> <td> <input type="text" name="EconomicActivityIncomeDeclarations[0].GrossIncome" id="EconomicActivityIncomeDeclarations_0__GrossIncome" /> </td

问题 i've created my own custom model binder to handle a Section DropDownList defined in my view as: Html.DropDownListFor(m => m.Category.Section, new SelectList(Model.Sections, "SectionID", "SectionName"), "-- Please Select --") And here is my model binder: public class SectionModelBinder : DefaultModelBinder { public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName); if

问题 as far as I understand a ModelBinder can generate class instances out of routedata/formdata . What I'm looking for is a way to manipulate the data handed over to the view before it is consumed by the view. What are the possiblities? Do I miss something obvious? Thanks in advance! EDIT I don't want to send clear IDs to the client but encrypt them (at least in edit cases). As it happens very often I want this step as much as possible automated. I look for something like a ModelBinder or a

问题 I have two instances of an Address.ascx control in an ASP.NET MVC page. <h1>Shipping Address</h1> <% Html.RenderPartial("Controls/AddressControl"); %> <h1>Billing Address</h1> <% Html.RenderPartial("Controls/AddressControl"); %> Of course, with the code exactly like this I'll end up with the same IDs for each field in the address. I can easily append a string to the ID of the fields so I'd have 'Street1_billing' and 'Street1_shipping' , but I'm not clear how to map this to the model. Whats

问题 I'm creating a custom model binder in an Mvc application and I want to parse a string to an enumeration value and assign it to the model property. I have got it working overriding the BindProperty method, but I also noticed that there is a SetProperty method. protected override void BindProperty(ControllerContext controllerContext, ModelBindingContext bindingContext, System.ComponentModel.PropertyDescriptor propertyDescriptor) { switch (propertyDescriptor.Name) { case "EnumProperty":

问题 Per my previous question, I implemented a model binder that maps /api/v1/widgets/1,2,3 to // WidgetsController.cs: public ActionResult Show(IEnumerable<int> idArgs) { } This was working for a while, but now it is not any longer. My ModelBinder is not even being invoked at all. When my action is invoked, idArgs has a value of the empty list, even if I set its default value to null in the route, which suggests to me that the default model binder thinks it's getting a value from somewhere.
