  public string GetUserID(string EmailAdd, string Password)
    {
        SqlConnection myConnection = new SqlConnection(@"user id=BankUser;password=Computer1;server=(local)\sql2008;database=BillionBank;");
        myConnection.Open();
        SqlCommand myCommand = new SqlCommand("SELECT * FROM [BillionBank].[dbo].[tblCustomerProfile] WHERE EmailAdd='" + EmailAdd + "' AND Password ='" + Password + "'", myConnection);
        SqlDataReader myreader;
        string result = "";

        myreader = myCommand.ExecuteReader();
        if (myreader.Read())
        {
            result = Convert.ToString(myreader["UserID"]);
        }

        return result;

    }

protected void btnLogin_Click(object sender, EventArgs e)
{
    Session["UserID"] = GetUserID(YOUR_EMAILID, YOUR_PASSWORD);
}
