Use @Html.EditorForModel() without polluting my domain entities with mvc assembly

Question

Is it possible to use the @Html.EditorForModel() method but not pollute my Domain entities like Product with HiddenInput,DataType(MultiLine) etc.. Attributes which needs the System.Web.Mvc assembly ?

Answer 1

Yes it's possible, but it will use the default for rendering things.
For example: strings will be one line textboxes.

There is no way to put this metadata somewhere else. (Unless you write new HTML helper by your own.)

What we usually do is, use a ViewModel for each Domain entity, and there we put the metadata.

Answer 2

I usually have two models - one is the domain entity, the other is specifically contains the attributes I want. Then I map/copy between the two of them. I have a simple class that automatically copies properties from one object to another, but you can manually do this or use something like Automapper. Then you use @Html.EditorFor against this new model.
