model-binding

I am using Knockout js. I have a view model that contains an array of objects and I want to allow the user to edit one of the objects using a wizard style interface. The issue I have is the wizard will show different steps depending on what choices are made . For instance: If the user selects 'Yes' on step 1 then I display step 2a If the user selects 'No' on step 1 then I display step 2b (ie. a different dialog form) This goes on so that the paths through the wizard are not linear. My question is do I bind all the possible wizard UI steps to the view model at start up even though some steps

I want to create a custom model binder in ASP.Net Web API. There are plenty of resources on how to do this from scratch, but I want to leverage existing functionality. I have looked around in the source on codeplex and can see plenty of modelbinders in there but most are sealed... and even then I can't work out which one would be used in which situations. Here is my api method header: public async Task<HttpResponseMessage> Post(long appId, [FromBody]Field field) What I want to do is basically intercept the modelbinder after it has populated all the basic properties, and then set some extra

What I want to do seems so simple. In my index.cshtml I want to display the WizardStepAttribute Value So, a user will see at the top of each page, Step 1: Enter User Information I have a ViewModel called WizardViewModel . This ViewModel has a property that is IList<IStepViewModel> Steps each "step" implements the Interface IStepViewModel, which is an empty interface. I have a view called Index.cshtml. This view displays EditorFor() the current step. I have a custom ModelBinder, that binds the View to an new instance of the concrete class implementing IStepViewModel based on the WizardViewModel

We are having an issue with Nancy's default model binder. Given the below... public class Foo { public Foo() { } public string Name { get; set; } public Bar Bar { get; set; } } public class Bar { public string Name { get; set; } } with elements like... <input type="text" value="Name" /> <input type="text" value="Bar.Name" /> With the default model binder used like so.. var foo = this.Bind<Foo>(); This correctly binds Foo.Name but fails to bind Foo.Bar.Name Is there a way to enable this kind of binding with the default binder or do we need to roll our own? If so are there any good examples? Why

My application has many models, many of which contain percentage data. These are represented as decimal or decimal? structs in the model. However, not all properties with decimal structs are percentages. Some should be treated like regular decimals. The percentages need special attention: For display, they should use {0:P2} format. (I have this part working.) For editing, they should allow the same format as the display, i.e. "95" or "95%" or "95.00 %" all bind to a value of 0.95. I started down the road of creating a PercentModelBinder that implements IModelBinder , but then realized that you

here is my ViewModel public class FaultTypeViewModel { [HiddenInput(DisplayValue = false)] public int TypeID { get; set; } [Required(ErrorMessageResourceType = typeof(AdministrationStrings), ErrorMessageResourceName = "FaultTypeNameRequired")] [Display(ResourceType = typeof(AdministrationStrings), Name = "FaultTypeName")] public string TypeName { get; set; } [Display(ResourceType = typeof(AdministrationStrings), Name = "FaultTypeDescription")] [DataType(DataType.MultilineText)] public string TypeDescription { get; set; } [Display(ResourceType = typeof(AdministrationStrings), Name =
