Hi mahesh213,

Using the below article i have created the example.

Custom Paging and Sorting using Entity Framework and jQuery in ASP.Net MVC

Check this example. Now please take its reference and correct your code.

Database

For this example I have used of Northwind database that you can download using the link given below.

Download Northwind Database

Model

public class CustomerModel
{
    public List<Customer> Customers { get; set; }
    public int PageIndex { get; set; }
    public int PageSize { get; set; }
    public int RecordCount { get; set; }
}

Controller

public class HomeController : Controller
{
    // GET: /Home/
    public ActionResult Index()
    {
        return View();
    }

    [HttpPost]
    public JsonResult AjaxMethod(string searchTerm, string sortColumn, string sortDirection, int pageIndex = 1)
    {
        NorthwindEntities entities = new NorthwindEntities();
        List<Customer> customers = new List<Customer>();
        if (!string.IsNullOrEmpty(searchTerm))
        {
            customers = entities.Customers.Where(x => x.ContactName.StartsWith(searchTerm)).ToList();
        }
        else
        {
            customers = entities.Customers.ToList();
        }
        switch (sortColumn)
        {
            case "":
            case "CustomerID":
                if (sortDirection == "ASC")
                {
                    customers = customers.OrderBy(x => x.CustomerID).ToList();
                }
                else
                {
                    customers = customers.OrderByDescending(x => x.CustomerID).ToList();
                }
                break;
            case "ContactName":
                if (sortDirection == "ASC")
                {
                    customers = customers.OrderBy(x => x.ContactName).ToList();
                }
                else
                {
                    customers = customers.OrderByDescending(x => x.ContactName).ToList();
                }
                break;
            case "City":
                if (sortDirection == "ASC")
                {
                    customers = customers.OrderBy(x => x.City).ToList();
                }
                else
                {
                    customers = customers.OrderByDescending(x => x.City).ToList();
                }
                break;
            case "Country":
                if (sortDirection == "ASC")
                {
                    customers = customers.OrderBy(x => x.Country).ToList();
                }
                else
                {
                    customers = customers.OrderByDescending(x => x.Country).ToList();
                }
                break;
        }

        CustomerModel model = new CustomerModel();
        model.PageIndex = pageIndex;
        model.PageSize = 10;
        model.RecordCount = customers.Count();
        model.Customers = customers.Skip((pageIndex - 1) * model.PageSize).Take(model.PageSize).ToList();

        return Json(model);
    }
}
