{
if (FormsAuthentication.Authenticate(username_Txt.Text, password_Txt.Text))
{
string username = username_Txt.Text;
FormsAuthentication.Initialize();
String strRole = username_Txt.Text;
FormsAuthenticationTicket fat = new FormsAuthenticationTicket(1,
username_Txt.Text, DateTime.Now,
DateTime.Now.AddMinutes(30), false, strRole,
FormsAuthentication.FormsCookiePath);
Response.Cookies.Add(new HttpCookie(FormsAuthentication.FormsCookieName,
FormsAuthentication.Encrypt(fat)));
Session["UserAuthentication"] = username;
Response.Redirect(FormsAuthentication.GetRedirectUrl(username_Txt.Text, false));
}

{
Label1.Text = "Invalid Email ID and Password";
