Asked by: udir

            SmtpClient client = new SmtpClient(ConfigurationManager.AppSettings["serverName"]);
            MailMessage mail = new MailMessage();
            mail.To.Add(address);
            mail.From = new MailAddress(ConfigurationManager.AppSettings["MailFrom"]);
            mail.IsBodyHtml = true;
            mail.Body = GetHTMLFromControl();
            client.Send(mail);
        }
        public static string GetHTMLFromControl()
        {
            SendMail addCtl = new SendMail();
            Control uc = addCtl.AddControl();
            StringWriter tw = new StringWriter();
            Html32TextWriter hw = new Html32TextWriter(tw);
            uc.RenderControl(hw);
            string html = Convert.ToString(tw);
            hw = null;
            tw = null;
            return html;
        }
        public Control AddControl()
        {
            string path = "Controls\\MyControl.ascx";
            Control uc = new Control();
            uc = LoadControl(path);
            return uc; 
        }

I think what you might want to do is overwrite the render method of the control and store the streamwriter information to a string variable/property and call that in your e-mail.

Hi strickdd,
thanks for the reply
How can i do it?
can u give an example from my code?
Thanks

Just make sure the control has rendered before using the Html property. This may not give the form values, let me know if it doesn't.

private string _html;
 
public string Html
{
   get { return _html; }
}
 
protected override void Render(HtmlTextWriter writer)
{
   _html = writer.write();
}
