I can not use Session In Page_Load and I got error bellow
- by LostLord
hi my dear friends ....
why i got this error :
Object reference not set to an
instance of an object.
when i put this code in my page_load.:
protected void Page_Load(object sender, EventArgs e)
{
BackEndUtils.OverallLoader();
string Teststr = Session["Co_ID"].ToString();
}
==========================================================================
this session is made when user logins to my web site and this session works in other areas...
thanks for your attention
==========================================================================
thanks for your answers
i removed BackEndUtils.OverallLoader(); but error still exists
i tried Teststr = Convert.ToString(Session["Co_ID"]); and error disappeared - but i don't know why that session is null
in other areas that session works perfectly = such as a button in that form
what is the matter?
my web page markup is like this :
<%@ Page Title="" Language="C#" MasterPageFile="~/Admin/AdminBackend.Master" AutoEventWireup="true" CodeBehind="Personel.aspx.cs" Inherits="Darman.Admin.Personel" Theme="DefaultTheme" %>
=================================================================================
i put this code in a button like this :
string Teststr = Convert.ToString(Session["Co_ID"]);
when i press that button THIS code in page Load(POSTBACK) + IN Button_Click works perfectly and shows me 23 (my Co_ID)
But when i run my page in browser (first time) this code in page load shows me null.
why?
thanks a lot
