Question

I have two database classes as defined below:

 public class TopDate
    {
        [Key]
        public int DateId { get; set; }
        public DateTime Date { get; set; }
    }
 public class TopSong
    {
        [Key]
        public int SongId { get; set; }        
        public string Title { get; set; }
        public int DateId { get; set; }
    }

where DateId is foreign key to TopSong

I am creating a controller through which i can create, delete or edit these database values.

When i right click on controller class and add controller i can only select one of the two classes defined above. Is there a way to make 1 controller to handle database updates to both these tables on one page?

Your controller should not be dealing directly with domain objects (meaning those things that are directly associated with your database). Create a ViewModel that contains the properties that you need, use your service layer to populate the ViewModel and your controller will use that as the Model for its base. An example of your ViewModel could be something like the following given your description above:

public class MusicViewModel
{
    public int SongId {get;set;}
    public string Title {get;set;}
    public IEnumerable<DateTime> TopDates {get;set;}
}

This view model would contain a list of all dates that a specific song was a Top Song.
