Handling input models

Question

I have a ViewModel which holds my InputModel as a property.

I use HTML helpers like so: @Html.TextBoxFor(m => m.InputModel.UserId) for example.

The problem is that this generates: <input name="InputModel.UserId" />

And the model-binder does not populate the properties in my HttpPost method:

public ActionResult Index(InputModel model)

I see there is a generic version of HTML helpers, I was thinking maybe I can leverage that somehow, but I havn`t yet figured out how. Or maybe there is a completley different way around this, that I'm not seeing since I am new to MVC.

Answer 1

You could either change your action to

public ActionResult Index(ViewModel model)

in which case the model.InputData would be populated or use Bind attribute

public ActionResult Index([Bind(Prefix="InputModel")] InputModel model)
