    Step 2 - C#

    using EmployeeTrackingSystemAndMIS.Models;
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Data.SqlClient;
using System.Linq;
using System.Web.Mvc;

namespace EmployeeTrackingSystemAndMIS.Controllers

    public class ClientController : Controller
    {
        private EmployeeTrackingSystemAndMISEntities db = new EmployeeTrackingSystemAndMISEntities();

        public string SearchMis()
        {
            string limit, start, searchKey, orderColumn, orderDir, draw, jsonString;
            limit = Request.QueryString["length"] == null ? "" : Request.QueryString["length"].ToString();
            start = Request.QueryString["start"] == null ? "" : Request.QueryString["start"].ToString();
            searchKey = Request.QueryString["search[value]"] == null ? "" : Request.QueryString["search[value]"].ToString();
            orderColumn = Request.QueryString["order[0][column]"] == null ? "" : Request.QueryString["order[0][column]"].ToString();

            var parameter = new List();
            var param = new SqlParameter("@orderColumn", orderColumn);
            parameter.Add(param);
            param = new SqlParameter("@limit", limit);

            var CompanySearchList = db.Database.SqlQuery("EXEC SearchCompany @orderColumn,@limit,@orderDir,@start,@searchKey ", parameter.ToArray()).ToList();

            dynamic newtonresult = new

                data = CompanySearchList
            };
            jsonString = JsonConvert.SerializeObject(newtonresult);

            return jsonString;
        }

        private class CompanySearch
        {
            public int TotalCount { get; set; }

    }
}



    Step 3 - Stored Procedure
    


    USE [EmployeeTrackingSystemAndMIS]

alter  procedure [dbo].SearchCompany

@orderColumn  int ,
@limit  int,
@orderDir  varchar(20),
@start  int,
@searchKey varchar(20)
  as 
  BEGIN

     declare @to as int = @start+@limit  

    select TotalCount = COUNT(c.CompanyID) OVER(), null as abc,c.Address,c.ClientID ,c.EmployeeID  , name,
    c.CompanyID 


     from CompanyTbl c  where c.Name like '%'+@searchKey+'%'

        order by
                    CASE WHEN @orderColumn = 1 AND @orderdir = 'desc' THEN c.[name] END DESC,
                    CASE WHEN @orderColumn = 1 AND @orderdir = 'asc' THEN c.[name] END ASC,
                    CASE WHEN @orderColumn = 2 AND @orderdir = 'desc' THEN c.[name] END DESC,
                    CASE WHEN @orderColumn = 2 AND @orderdir = 'asc' THEN c.[name] END ASC


                    OFFSET @start ROWS
                              FETCH NEXT @to ROWS ONLY

  End
