hi all. am trying to implement paging bar( < 1 2 3 >) bottom of result page.. my code
am getting
Object reference not set to an instance of an object.

someone help me to solve this :(

Controller

[HttpPost]
public ActionResult Index(string txtValue, string txtLocation, string Filter_Value, int? Page_No)
{
var s = txtValue.ToString();
Session["searched"] = s;
var l = txtLocation.ToString();
Session["location"] = l;


ViewBag.plist = txtValue;
if (txtValue != null)
{
Page_No = 1;
}
else
{
txtValue = Filter_Value;
}

ViewBag.FilterValue = txtValue;



if (txtValue.Length > 0)
{
string[] keywords = txtValue.Trim().Split(new string[] { " " }, StringSplitOptions.RemoveEmptyEntries);
string[] keyword = txtLocation.Trim().Split(new string[] { " " }, StringSplitOptions.RemoveEmptyEntries);
var parameter = new SqlParameter[2];
parameter[0] = new SqlParameter { ParameterName = "@SEARCH", Value = txtValue };
parameter[1] = new SqlParameter { ParameterName = "@loc", Value = txtLocation };
List<search> cm = new List<search>();
using (SYTEntities context = new SYTEntities())
{
cm = context.Database.SqlQuery<search>("exec search_filter_sp @SEARCH,@loc", parameter).ToList();

}
//int Size_Of_Page = 3;
//int No_Of_Page = (Page_No ?? 1);
return View(cm.ToList().ToPagedList(Page_No?? 1, 3));
}

{
ViewBag.Message = true;
return View();
