Question

I have 2 class in Model

public class User
{
    public int UserID { get; set; }
    public string UserName { get; set; }
}

public class Product
{
    public int ProductID { get; set; }
    public string ProductName { get; set; }
}

I have a view that use both class and I need use html.TextBoxFor.
I can create BigModel:

public class BigModel
{
    public User user;
    public Product product;
}

so in View:

@model BigModel
@Html.TextBoxFor(m=> m.user.UserName)
@Html.TextBoxFor(m=> m.product.ProductName)    

Or i can use different partial view and reander them. But they are not my favorite solution.

Isn’t there another way? such as:

<p>    
    User Name:
    @Html.TextBoxFor<User>(u=> u.UserName)
</p>
<p>    
    Product Name:
    @Html.TextBoxFor<Product>(p=> p.ProductName)
</p>

Answer 1

Look at TextBoxFor method signature:

public static MvcHtmlString TextBoxFor<TModel, TProperty>(
this HtmlHelper<TModel> htmlHelper,
Expression<Func<TModel, TProperty>> expression
)

It’s impossible. to write:

@Html.TextBoxFor<Product>(p=> p.ProductName)

So you are “stuck” with this:

@Html.TextBoxFor(m=> m.product.ProductName)

(I don’t know why you prefer the first version, it’s even one char longer… =) )
