Lately I’ve been playing around with Asp.Net Mvc. I’m trying to adapt the NerdDinner sample for a project I’m working on. The sample includes a class called PaginatedList<T>.  PaginatedList<T> looks something like this:

   public class PaginatedList<T> : List<T>
   {
        public int PageIndex  { get; private set; }
        public int PageSize   { get; private set; }
        public int TotalCount { get; private set; }
        public int TotalPages { get; private set; }
   }

My controller method looks something like this:

   public ActionResult FindBusinessesByName(string businessName, int limit, int page)
   {
      BusinessRepository repository = new BusinessRepository();
      PaginatedList<Business> paginatedBusinesses = new PaginatedList<Business>(repository.FindBusinessesByName(businessName), page, limit);
      return Json(paginatedBusinesses);
   }

I’m using jQuery to get a PaginatedList of businesses from my controller. I use the list of businesses to create an unordered list to display the business information. I haven’t played with jQuery or json serialization much so I was surprised to see that only the business data was returned. The extra properties on the PaginatedList were not.
