title: ASP.NET MVC add HiddenInput attribute to Model in DLL
body: <p>I'm working on an asp.net MVC 3 application which is using Data Models from a compiled library.  However I would like to be able to add the following declaration to some data model properties in the compiled dll:</p>
  
  <pre><code>[HiddenInput(DisplayValue = false)]
  </code></pre>
  
  <p>The problem is that I don't have the source for the DLL and the author doesn't want to introduce a dependency on System.Web.Mvc.  Is there a way, using partial classes or something like that, that would allow me add this attribute?</p>
  
  <p>Mark</p>
