Sending aspx page content in mail body using c# asp.net

In some cases we need to send the all data rendered on aspx page in mail body, so i have implemented this functionality in my code.



I have one user registration form for some event registration. This form is displayed on website for taking registration from users for the event. So here I am taking registration of a user, details of user are stored in my database as well as i want to send the registration confirmation to the user or as it is registration form after successful submission. So to perform this i need to write code as follows:

Add this line of code on aspx page directive .
EnableEventValidation="false"  

here is code behind of aspx on submit button

private void SendFormInMail()
    {
        try
        {
            string host = "smtp.gmail.com";
            string mailFrom = "MymailId@gmail.com";
            string password = "myPassword";
            int port = 587;

            System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient();
            client.Credentials = new System.Net.NetworkCredential(mailFrom, password);
            client.Port = port;
            client.Host = host;
            client.EnableSsl = true;

            System.Net.Mail.MailMessage email = new System.Net.Mail.MailMessage();
            email.To.Add(txtEmail.Text.Trim());
            email.CC.Add("anothermail Id@domain");
            email.From = new System.Net.Mail.MailAddress(mailFrom); 
            email.Body += "Dear " + txtFirstName.Text.Trim() + ",<br/><br/>";
                     
            email.Body += GetPageData();
            email.Body += "<img id='img1' runat='server' src='http://signatureImage.png'/>";
            email.Body += "<br/> Regards,<br/> Gajanan.";
            email.Subject = "abcd event Registration";
            email.IsBodyHtml = true;

            client.Send(email);
          
            Response.Redirect("~/RegistrationConfirmation.aspx");
        }
        catch (Exception ex)
        {          
                 ex.Message;
        }
    }

    public string GetPageData()
    {
        StringBuilder strBuilder = new StringBuilder();        
        StringWriter strWriter = new StringWriter(strBuilder);
        HtmlTextWriter htw = new HtmlTextWriter(strWriter);
        this.form1.RenderControl(htw);
        return strBuilder.ToString();

    }

By using above code, you can achieve this.
I hope this post will help you.

Thanks,
