Question

My URL length is capped at 2084 characters and I have forms that need to have essay’s emailed. I am not using MVC, not sure if that matters. Forms are set to POST data, runat=server. I just want the code behind the main page to load and send an email, I don’t need all the variables passed in the URL. Is this possible or does ASP.net just fill up the URL with VIEWSTATE data? If so, how can I send an email with this data without it going in the url?

Oh I also edited the web.config to allow a larger maxQueryStringLength but from what I am reading older browsers don’t really support that anyway.

<form id="infoForm" runat="server" name="contactForm" method="POST" action="#">
  <!--Other form stuff here-->
         <asp:Button class="button" id="submitButton" Text="Submit" runat="server"
         onclick="submitButton_Click" />
</form>

If you are sending an email you don’t need to send the data via the URL. You just send an e-mail using System.Net.Mail and your form data goes into the e-mail.

Code sample below:

protected void Btn_SendMail_Click(object sender, EventArgs e)
{
    MailMessage mailObj = new MailMessage(
        txtFrom.Text, txtTo.Text, txtSubject.Text, txtBody.Text);

    SmtpClient SMTPServer = new SmtpClient("localhost");

    try
    {
       SMTPServer.Send(mailObj);
    }
    catch (Exception ex)
    { 
        Label1.Text = ex.ToString();
    }
}
