Session["timeout"] = DateTime.Now.AddHours(Convert.ToDouble(1)).AddMinutes(Convert.ToDouble(0)).AddSeconds(Convert.ToDouble(0)).ToString();
}
}

{
if (0 > DateTime.Compare(DateTime.Now, DateTime.Parse(Session["timeout"].ToString())))
{
lblTimer.Text = string.Format("Time Left: 00:{0}:{1}", ((Int32)DateTime.Parse(Session["timeout"].ToString()).Subtract(DateTime.Now).TotalMinutes).ToString(), ((Int32)DateTime.Parse(Session["timeout"].ToString()).Subtract(DateTime.Now).Seconds).ToString());
}
else
{
timer1.Enabled = true;
Response.Redirect("Logout.aspx");
}
}
}
When Timer is ticking - I CAN'T Select Favourite Actor. Look's like the Drop Down List also refresh.
What I need to do to make sure only UpdatePanel1 is refresh when Timer is Ticking???
