Question

i want to do sorting in the mvc contrib grid….so far i have i used this coding in

homecontroller.cs

public ActionResult Sort(GridSortOptions Sort)
    {
        using (ProductsDataContext db = new ProductsDataContext())
        {
            var categories = db.Products.ToList();
            if (Sort.Column != null)
                categories =categories.OrderBy(Sort.Column, Sort.Direction);
            ViewData["sort"] = Sort;
            return View(categories);

        }

    }

Here i am getting a error:

Cannot implicitly convert type
‘System.Collections.Generic.IEnumerable’
to
‘System.Collections.Generic.List’.
An explicit conversion exists (are you
missing a cast?)

Answer 1

Either change this line:

var categories = db.Products.ToList();

to this:

var categories = db.Products;

Or change this line

categories =categories.OrderBy(Sort.Column, Sort.Direction);

to this:

categories =categories.OrderBy(Sort.Column, Sort.Direction).ToList();
