Ok, Google (Gmail) is hosting our emails through "domain sharing". Basically, any emails being sent to raylinder@glacsy.com goes to Gmail and Gmail hosts it. My concern was SMTP from our website in ASP.NET 2.0. Yes, sound overwhelmingly exciting doesn't it? Well, there's is a way, the LONG and easier way or the short and painful way. LONG and easier way is, you build a SMTP class/control and namespace it to something like Glacsy.Net.WebMail then create a the SMTP assembly to accept parameters like From, To, BCC, Subject, Body. Then every page you want to send email, just map it to the class. Long time to build it, easy to use. I'm not getting into the short and painful way, you can just use your imagination. Below is some code on your page (yes, finally I'm including code):

Glacsy.Net.WebMail.SMTP("welcome@glacsy.com", someone@their-email.com, "bcc@some-one-else.com", "My Subject", "My body or message...");

using System.Net;
using System.Net.Mail;
using System.Text;

namespace Glacsy.Net
{
    public class WebMail
    {
        public static void SMTP(string from, string to, string bcc, string subject, string body)
        {
            MailMessage mailMsg = new MailMessage();
            mailMsg.From = new MailAddress(from);
            mailMsg.To.Add(to);
            mailMsg.Subject = subject;
            mailMsg.IsBodyHtml = true;
            mailMsg.BodyEncoding = Encoding.UTF8;
            mailMsg.Body = body;
            mailMsg.Priority = MailPriority.Normal;
            // Smtp configuration
            SmtpClient client = new SmtpClient();
            client.Credentials = new NetworkCredential("youremail@gmail.com", "yourpassword");
            client.Port = 587; //or use 465            
            client.Host = "smtp.gmail.com";
            client.EnableSsl = true;
            object userState = mailMsg;
            try
            {
                //you can also call client.Send(msg)
                client.SendAsync(mailMsg, userState);
            }
            catch (SmtpException)
            {
                //Catch errors...
            }
        }
    }
}

When reading data from a database using the Page_Load event and then updating the database, the data doesn't get updated as described here.

By including

if (!Page.IsPostback)

in before the reader allows data to be updated in other areas on the page/form. Below are examples:

Update doesn't work:
==================================================================

protected void Page_Load(object sender, EventArgs e)
{
      DataList1.DataBind(); 
}

protected void DataList1_UpdateCommand(object source, DataListCommandEventArgs e)
{
      SqlConnection sqlConn = new SqlConnection("connection");
      SqlCommand sqlComm = new SqlCommand("UPDATE blog_Postings SET title = @title, body = @body WHERE (id = @id)", sqlConn);

      sqlComm.Parameters.Add(new SqlParameter("@id", SqlDbType.Int));
      sqlComm.Parameters["@id"].Value = intID;
      sqlComm.Parameters.Add(new SqlParameter("@title", SqlDbType.NVarChar));
      sqlComm.Parameters["@title"].Value = strTitle;
      sqlComm.Parameters.Add(new SqlParameter("@body", SqlDbType.NVarChar));
      sqlComm.Parameters["@body"].Value = strBody;

      sqlComm.CommandType = CommandType.StoredProcedure; 

      sqlConn.Open();
      sqlComm.ExecuteNonQuery();
      sqlConn.Close();
      sqlComm.Dispose();

      DataList1.EditItemIndex = -1;
      DataList1.DataBind();
}

When the DataList is updating, the function protected void Page_Load(object sender, EventArgs e) runs again/refreshes which retrieves the old values in the database.


Update works:
==================================================================

protected void Page_Load(object sender, EventArgs e)
{
      if (!Page.IsPostBack)
      {
            DataList1.DataBind();
      } 
}

protected void DataList1_UpdateCommand(object source, DataListCommandEventArgs e)
{
      SqlConnection sqlConn = new SqlConnection("connection");
      SqlCommand sqlComm = new SqlCommand("UPDATE blog_Postings SET title = @title, body = @body WHERE (id = @id)", sqlConn);

      sqlComm.Parameters.Add(new SqlParameter("@id", SqlDbType.Int));
      sqlComm.Parameters["@id"].Value = intID;
      sqlComm.Parameters.Add(new SqlParameter("@title", SqlDbType.NVarChar));
      sqlComm.Parameters["@title"].Value = strTitle;
      sqlComm.Parameters.Add(new SqlParameter("@body", SqlDbType.NVarChar));
      sqlComm.Parameters["@body"].Value = strBody;

      sqlConn.Open();
      sqlComm.ExecuteNonQuery();
      sqlConn.Close();
      sqlComm.Dispose(); 

      DataList1.EditItemIndex = -1;
      DataList1.DataBind();
}

So, as you can see by not validating the postback will causes data not to update which will lead into hours of frustration. Enjoy...
