ASP.Net MVC 3 JQGrid

Question

After reading up on the JQGrid control, I decided it would be good to use it in one of my ASP.Net MVC 3 Web applications.

Firstly I followed Phil Haacks tutorial htt

EF doesn't support ToString method, you must retrieve the data without ToString and format

this should work

public ActionResult LinqGridData(string sidx, string sord, int page, int rows)
{
    AssetEntities context = new AssetEntities();

    var query = from e in context.Equipments
                select e;

    var count = query.Count();

    var result = new
    {
        total = 1,
        page = page,
        records = count,
        rows = query.Select(x => new { x.equipamentID, x.Category.categoryTitle,x.Department.title })
                    .ToList() // .AsEnumerable() whatever
                    .Select(x => new { 
                        id = x.equipamentID,
                        cell = new string[] {
                            x.equipamentID.ToString(),
                            x.categoryTitle,
                            x.title
                        }})
                    .ToArray(),
    };

    return Json(result, JsonRequestBehavior.AllowGet);

}
