Question

I want to fill jqGrid from a stored procedure, there was 1 good example is given at following link, but my problem is that I am not using model to retrieve data, any SOLUTION ?

I am using jqGrid + SQL Server 2008 + ASP.net MVC3 (c#)

Example of jqGrid filling by stored procedure with Model

Here by am giving the code that i am using currently

VIEW CODE

$(document).ready(function () {
        $('#History').jqGrid({
            //url from wich data should be requested
            url: '@Url.Action("UploadData")?entity=' + getEntity(),

            //type of data
            datatype: 'json',
            //url access method type
            mtype: 'GET',
            //columns names
            colNames: ['ID', 'File','Uploaded', 'By'],
            //columns model
            colModel: [
                            { name: 'ID', index: 'ID', align: 'left', editable: false },
                            { name: 'File', index: 'File', align: 'left', editable: false, formatter: "text", width: '105px' },
                            { name: 'Uploaded', index: 'Uploaded', align: 'left', editable: false, formatter: "text", width: '102px' },
                            { name: 'By', index: 'By', align: 'left', editable: false, formatter: "text", width: '78px' },
                          ],
            //pager for grid
            pager: $('#Historypager'),
            //number of rows per page
            rowNum: 15,
            //initial sorting column
            sortname: 'File',
            //initial sorting direction
            sortorder: 'asc',
            //we want to display total records count
            viewrecords: true,
            //Sets the caption for grid
            caption: 'Upload History',
            //grid height
            height: '100%'

        });

        $('#History').jqGrid('navGrid', '#Historypager', { add: false, del: false, edit: false, search: false });

        $('#History').jqGrid('hideCol', "ID");
        var dialogPosition = $(this).offset();
    });

CONTROLLER METHOD

public JsonResult UploadData(string sidx, string sord, int page, int rows, string entity)
        {
            int pageIndex = Convert.ToInt32(page) - 1;
            int pageSize = rows;
            var entitytype = Request.QueryString["entity"].ToString().Trim();
            var uploadlist = objEntities.Uploads.Where(u => u.TableName == entitytype).ToList().AsQueryable(); // fetches the data from upload table

            int totalRecords = uploadlist.ToList().Count(); // total records in the current table
            int totalPages = (int)Math.Ceiling((float)totalRecords / (float)pageSize); // counts the total no. of pages

            if (sord.Trim().ToLower() == "asc") // fetches data according the sorting order
                uploadlist = uploadlist.OrderBy(x => TypeHelper.GetPropertyValue(x, sidx)).Skip(pageIndex * pageSize).Take(pageSize);
            else
                uploadlist = uploadlist.OrderByDescending(x => TypeHelper.GetPropertyValue(x, sidx)).Skip(pageIndex * pageSize).Take(pageSize);

            // fetches data and sets it in JSON format
            var jsonData = new
            {
                total = totalPages,
                page = page,
                records = totalRecords,
                rows = (from b1 in uploadlist
                        select new
                        {
                            id = b1.ID,
                            cell = new string[] {
                                Convert.ToString(b1.ID),
                                b1.File,
                                Convert.ToString(b1.Uploaded),
                                Convert.ToString(b1.By)
                            }
                        }).ToArray()
            };

            return Json(jsonData, JsonRequestBehavior.AllowGet); // returns the data back to the jqgrid
        }

In this Example i’ve used LINQ demo, but now in new task i’ve to use Stored Procedure to fetch the data…

CONTROLLER CODE

var uploadlist = SPforData(sidx, sord, page, rows /* , +other parameters */).ToList();
                int totalRecords = 0;
                foreach (var pr in uploadlist)
                {
                    totalRecords = Convert.ToInt32(pr.Total);
                    break;
                } // here I am fetching total number of records that have been returned from SP

        int totalPages = (int)Math.Ceiling((float)totalRecords / (float)pageSize); // counts the total no. of pages

        var jsonData = new
        {
            total = totalPages,
            page = page,
            records = totalRecords,
            rows = (from pr in uploadlist
                    select new
                    {
                        id = pr.ID,
                        cell = new string[] {
                            Convert.ToString(pr.ID),
                            Convert.ToString(pr.Name),
                            Convert.ToString(pr.Age),
                            Convert.ToString(pr.Qualification),
                        }
                    }).ToArray()
        };

        return Json(jsonData, JsonRequestBehavior.AllowGet); // returns the data back to the jqgrid
