jQuery Grid Plugin - jqGrid

I am proviidng my controller code to populate the grid. I have not written any code to export in the controller. I am assuming that, JQGrid will do the export functionality. If not would you please provide me a link or if there is any code published already in this help forum in case if you know.

This is my controller code to populate the grid:

public virtual JsonResult GetJQGridJsonData(int page, int rows, string search, string sidx, string sord)
        {
            List<Product> jqData = new List<Product>();
            jqData = Repository.GetProducts();

            int pageSize = rows;
            int totalRecords = jqData.Count();

            int totalPages;
            if (totalRecords > 0)
                totalPages = (int)Math.Ceiling((float)totalRecords / (float)pageSize);
            else
                totalPages = 0;

            // if for some reasons the requested page is greater than the total set the requested page to total page
            if (page > totalPages) page = totalPages;

            //total – Total number of Pages.
            //page – Current page Index.
            //records – Total number of records in the rows group.
            //rows – An array with the data plus an identifier.
            //id – The unique row identifier, needs to be an int from what I have found.
            //cell – An array of the data for the grid.
            var jsonData = new JqGridJsonData
            {

                total = totalPages,
                page = page,
                records = totalRecords,

                rows = jqData.Select(vm =>
                             new JQGridRowJson
                             {
                                 id = vm.ProductId.ToString(),
                                 cell = new[]{

                                                   vm.ProductId.ToString(),
                                                   vm.ProductNumber,
                                                   vm.Size,
                                                   vm.ReleaseDate.ToShortDateString(),
                                                   vm.Amount.ToString(),
                                                   vm.Description,
                                                                                                 
                                }
                             }).ToArray()

            };
            //<a href="http://www.pageresource.com/linkus.htm" /> </a>
            return Json(jsonData, JsonRequestBehavior.AllowGet);
        }
