asp.net mvc nested view model form sumission

Question

Is it possible to only accept post back values from a nested view model? For example, I would like to post only the 'Address': ` ``` @Html.TextBoxFor(p => p.User.Account.Address.Street) @Html.ValidationMessageFor(p => p.User.Account.Address.Street) ``` ` To this controller action:` ``` [HttpPost] public ActionResult SaveAddress(Address address) { // save to db here } ``` ` Currently the values only post back if I pass the Address to it's own partial view so that the properties look like:` ``` @Html.TextBoxFor(p => p.Street) @Html.ValidationMessageFor(p => p.Street) ``` `

Accepted Answer

You could specify the binding prefix:

```
[HttpPost]
public ActionResult SaveAddress([Bind(Prefix = "User.Account")] Address model) 
{
    ...
}
```

Another possibility is to use a partial:

```
@Html.Partial("_Address", Model.User.Account.Address)
```

and inside `_Address.cshtml`:

```
@model Address
@Html.TextBoxFor(p => p.Street)
@Html.ValidationMessageFor(p => p.Street)
```
