This is the quick and easy approach.  Note you have to provide the database IP address, database name, username and password into this line:

command.Connection = new SqlConnection("Server=;Database=DatabaseName;User ID=sa;Password=xxxx;");

Html Markup:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm2.aspx.cs" Inherits="WebApplication4.WebForm2" %>

<!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">
    <form id="form1" runat="server">
        <asp:Button ID="btnExportData" runat="server" Text="Export Data" OnClick="ExportData_Click" />

Open in new window

Code Behind:
using System;
using System.Collections.Generic;
using System.Data;
using System.Data.SqlClient;
using System.IO;
using System.Text;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace WebApplication4
    public partial class WebForm2 : System.Web.UI.Page
        protected void Page_Load(object sender, EventArgs e)


        protected void ExportData_Click(object sender, EventArgs e)
            DataTable table = new DataTable();

            using (SqlCommand command = new SqlCommand())
                    command.Connection = new SqlConnection("Server=;Database=DatabaseName;User ID=sa;Password=xxxx;");
                    command.CommandText = "SELECT * FROM [Table] ORDER BY [Column]";

                    SqlDataAdapter adapter = new SqlDataAdapter(command);
                catch(Exception ex)
                    //error happened while getting data:
                    string error = ex.ToString();

            GridView grid = new GridView();
            grid.DataSource = table;

            StringWriter stringWriter = new StringWriter();
            HtmlTextWriter htmlWriter = new HtmlTextWriter(stringWriter);

            Response.AddHeader("content-disposition", "attachment; filename=ExcelFileName.xls");
            Response.Charset = "";
            Response.ContentType = "application/excel";

Wow! Thanks for the detailed response. I should have given more guidance as I wasn't initially looking for code example.  At this point, I was just looking for a sense of general direction so I can do more investigating of my own.  However, you read my mind and was able to push me in the right direction.  Much appreciated for the help.
