ASP.NET MVC DefaultModelBinder with nested lists

Question

I have a View with a table representing an employee\'s timesheet. Days across the top, projects down the side, with each day/project intersection containing two values for regul

Answer 1

I eventually figured out why DefaultModelBinder wasn't picking up on the properties of WorkUnit: Because they weren't properties, they were fields. DefaultModelBinder only works with properties. Changing the class definition of WorkUnit and Project to use fields made everything click:

public class Project {
    public IList WorkUnits { get; set; }
    public string Name { get; set; }
}

public class WorkUnit {
    public DateTime Date { get; set; }
    public decimal RegularHours { get; set; }
    public decimal OvertimeHours { get; set; }
}

(Note: The source code in the original question had Project.Name defined as a field, in my actual code it was a property. This is why the Projects list was getting populated but WorkUnits wasn't.)
