I am trying to create a control to allow users to add themselves to our Constant Contact newsletter. I got code from them that contains a <form> so I decided to creaet a control to avoid that. Problem is that I am using SiteFinity...they do not support using PostBackUrl on a button in their content editors. Their response to fix the bug in their system, was to use Response.Redirect. Problem is that there are hidden fields in the control (shown below). I really dont want to have to dig into their API as this should work. How can I get it so that the control will submit to Constant Contact's site without using PostBackUrl on the button?? Here is what I have:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="NewsletterSignup.ascx.cs"
Inherits="NewsletterSignup" %>
