Hello everyone,

I m facing error while performing manual paging. I m getting this error.

Controller: (Datasourceurl)

// Class for storing result and totalcount.

class Res
{
public IEnumerable<Student> Records { get; set; }
public int TotalRecordsCount { get; set; }
}

public JsonResult Data()
{

var absolutepath1 = Request.QueryString.Value;
NameValueCollection parse1 = HttpUtility.ParseQueryString(absolutepath1);
int skip = Convert.ToInt32(parse1["$skip"]);//number of rows to skip
int top = Convert.ToInt32(parse1["$top"]);// entries to be displayed

IEnumerable<Student> s12

if (skip != null && top != null)
{

s12= data.GetStudents();
s12 = s12.Skip(skip).Take(top).ToList();

Res r1 = new Res();
r1.Records = s12;
r1.TotalRecordsCount = s12.Count();

return Json(r1);

}

return Json(s12);

}

$("#grid").igGrid({
