MVC 3: Hide ID property using EditorForModel

I have this line in my View:

@Html.EditorForModel()

And this is my ViewModel:

public class CommentForm
{
    public int Id { get; set; }

    [DisplayName("Kommentar"), DataType(DataType.MultilineText)]
    public string Comment { get; set; }
}

The problem is that Id renders as a textfield in the form. Actually, I only want to use Id in the form action. Is there an attribute that tells the editor not to render the property Id?

Setting ShowForDisplay and ShowForEdit to false is already done by the standard

 [System.ComponentModel.DataAnnotations.ScaffoldColumn(false)]

attribute. Your custom attribute therefore seems like overkill.

Thanks for your contributions, but I didn't really like them.

I made my own PreventRenderingAttribute.

PreventRenderingAttribute.cs

[AttributeUsage(AttributeTargets.Property)]
public class PreventRenderingAttribute : Attribute, IMetadataAware
{
    public void OnMetadataCreated(ModelMetadata metadata)
    {
        metadata.ShowForDisplay = false;
        metadata.ShowForEdit = false;
    }
}

And in CommentForm

[PreventRendering]
public int Id { get; set; }

One possibility is to render it as a hidden field:

[HiddenInput(DisplayValue = false)]
public int Id { get; set; }

Another possibility is to write a custom editor template for your CommentForm view model and inside this template include whatever you want (~/Views/Shared/EditorTemplates/CommentForm.cshtml):

@model CommentForm
<div>
    @Html.EditorFor(x => x.Comment)
</div>
