Model Binding to a Custom Class MVC

Question

I'm trying to do model binding to a list of a custom class. However when ever I check the values in the controller they all appear as their default values.

I have this class

public class ItemsViewModel
{
     public int ID;
     public decimal RoyaltyPercent = 0;
     public decimal ListPrice = 0;
     public int Parts = 0;
     public decimal RemitPercent = 0;
     public DateTime? DiscontinuedDate;
}

and this form:



            @**@

        

        @foreach (var it in Model.Items)
        {


            

            ItCount++;
        }
    
    
        
            Format Code
            Parts
            List Price
            ISBN
            Discontinue Date
            Hide from eComm
            Date Created
            Royalty %
            Remit % Save

                
                
                    
                
                
                    
                
                
                    
                
                @tDisDate
                     
                
                
                    
                
                @it.InsTimeStamp.ToString("MM/dd/yyyy")

this is the Method stub for the in the Update action in the controller:

 public ActionResult UpdateItems(int TitleID, ItemsViewModel[] IVM, List HideFromEcomm) {}

The View Model isn't binding, is it possible that I'm not naming them correctly, This model is not being passed into the view so I cannot use Textboxfor. Any suggestions on how to fix this, also a bonus if you have resources on where I can read more about the model binder in MVC

Binder only works with properties, not fields. Change you class ItemsViewModel to user properties instead of fields:

public class ItemsViewModel
{
     public int ID { get; set; }
     public decimal RoyaltyPercent { get; set; }
     public decimal ListPrice { get; set; }
     public int Parts { get; set; }
     public decimal RemitPercent { get; set; }
     public DateTime? DiscontinuedDate { get; set; }
}
