title: Asp.net MVC populate related fields from primary field
body: <p>Using asp.net MVC, is there a best-practice approach to populating related fields asyncronously once a user as entered a primary key field.  eg, Once the user has entered EmployeeID on the form, the employeeName should populate if the entered EmployeeID is valid. </p>
  
  <p>(I am already using the RemoteAttribute to validate that the entered EmployeeID is valid or not, and was hoping that this would be able to return related fields somehow, since it is already making the call to the repository.)</p>
