• Re: Business Logic Layer in the Presentation Layer

  Thanks for the help Nai, I end up recreating the fields as properties on the BLL, this way I can scalate that same BLL to another Presentation Layer in any form. Your sugestion was using DataTables I guess but I never was a big fan of them. So thanks anyway

  I just begun to develop my web app with LINQ to SQL but I want to get it right from the beginning. I created 2 class libraries: BLL and DAL. In the DAL I created the mapping for my LINQ to SQL to the Northwind DB. In the BLL I created a method like this: public Product GetProductById( int id) { NorthWindDataContext dc = new NorthWindDataContext(); Product result = dc.Products.SingleOrDefault(c => c.ProductID == id); return result; } Which return a single row of Product type that belong to the
