ReadOnly Attribute in MVC 4

I assume you use this property in a view with something like EditorFor? Then use:

[Editable(false)]
public string MyProperty {get;set;}

or

@Html.TextBoxFor(x => x.MyProperty, new { readonly = "readonly" })

If you want a readonly public property of a class use:

public string MyProperty {get; private set;}

@Html.EditorFor(
  model => model.id_to_fetch,
  new {
    htmlAttributes = new {
      @class = "form-control" , @readonly = "readonly"
    }
  }
)
