How to modify the session variable inside the asp.net webmethod

Question

I have following webmethod where i want to modify the value of the existing Session variable but here inside the webmethod whenever i assign the value to that session variable, the value is not assigning to it.

WEBMETHOD

 [WebMethod(EnableSession = true)]
    public static List<tblCustomerList> CustData(String id)
    {
        Int32 count=(Int32) HttpContext.Current.Session["pgnum"];
        HttpContext.Current.Session["pgnum"] = count++;
        DataGridEntities _dbContext = new DataGridEntities();
        var filteredResult = _dbContext.tblCustomerLists.ToList();
        return filteredResult;
    }

should not you use the ++count , what do you mean by not assigning — Devesh

In your code you should do like this, because count++ will assign the existing value and then increment its value

          HttpContext.Current.Session["pgnum"] = ++count;
