Question

Now, I realize that this question has been answered before, but I just can’t warp my head around it and make it work in my example:

View
should contain 2 foreach loops fx
foreach(var item in Model.ListA)
foreach(var item in Model.ListB)

Model
should contain a class with a LinqDataContext object and two properties: (ListA and ListB)

Controller
should pass the Model through the View.

How would the Model and Controller look to achieve this?
Some simple code examples would be really helpful 🙂

You’ve got it a bit backward. Your data context should be in the controller (preferably in a layer even lower that the controller uses). You always want your controller responsible for getting/updating data, and populating the model. Then, the model is delivered to the view with everything needed for the presentation of that data.

public class MyModel
{
    public List<ListAEntity> ListA {get;set;}
    public List<ListBEntity> ListB {get;set;}
}


public class HomeController : Controller
{
    private readonly MyDataContext _context = new MyDataContext();

    public ActionResult Index()
    {
        var model = new MyModel()
        {
            ListA = _context.Get<ListAEntity>().ToList(),
            ListB = _context.Get<ListBEntity>().ToList()
        };

        return View(model);
    }
}
