<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">

    <style type="text/css">
        .modalBackground
        {

    </asp:Panel>

using System.Configuration;
using System.Data;
using System.Data.SqlClient;

public partial class Mailjavascript : System.Web.UI.Page
{
    string conStr = ConfigurationManager.ConnectionStrings["NORTHWNDConnectionString"].ConnectionString.ToString();
    protected void Page_Load(object sender, EventArgs e)
    {
        SqlConnection s1 = new SqlConnection(conStr);
        s1.Open();

        string queryString = "SELECT * FROM employee";
        SqlDataAdapter adapter = new SqlDataAdapter(queryString, s1);

        DataSet employee = new DataSet();
        adapter.Fill(employee, "employee");

        s1.Close();
