title: ASP.NET DynamicData edit logic for depending fields
body: <p>I want to control some fields in a dynamic data edit page. </p>
  
  <p>So for example : 
  when a specific type is chosen in a combobox, other input fields should be disabled or should be set to a specific value. </p>
  
  <p>How should this logic be implemented, a custom edit page ? 
  Or can it be controlled from the model metadata ?</p>
