I assume you're going for a ToggleButton sort of thing? If so that can be done by using a bool value at class scope.

Hi,

If U have problem using session variable then probably u can use any of App_Code class with a static string in it. assign its value once user is authenticated.

Hi,
change your above code to following.

C#

protected void Page_Load(object sender, EventArgs e)
{
    if(!IsPostBack)
    {
          string user = Convert.ToString(Session["user"]);
          if (user != null)
          {
              signin_btn.Text = "sign out";
              lbl_email.Text = Convert.ToString(Session["user"]);
          }
          else if(user==null)
          {
              signin_btn.Text = "Sign in";
              Response.Redirect("login.aspx");
          }
    }
}

protected void signin_btn_Click(object sender, EventArgs e)
{
    string user = Convert.ToString(Session["user"]);
    if (user != null && signin_btn.Text == "sign out")
    {
        Session.Clear();
        Session.Abandon();
        signin_btn.Text = "sign in";
        Response.Redirect("login.aspx");
    }
}

Hope it helps.
