Just as an aside to anyone who's listening, here's how you do this if you want to capture the output and then still display the ASP.Net page which requires writer.Write() with the generated string.
In my scenario I need to display the result page and use a portion of it for my Email confirmation, so I simply capture the content strip out some stuff then send it:
protected override void Render (HtmlTextWriter writer)
{
StringBuilder sb = new StringBuilder();
HtmlTextWriter hWriter = new HtmlTextWriter(new StringWriter(sb));
base.Render(hWriter);
string PageResult = sb.ToString();
writer.Write(PageResult);
string Confirmation = wwUtils.StrExtract(PageResult,"<!-- Start Confirmation Display --->",
"<!-- End Confirmation Display --->");
if (wwUtils.Empty(Confirmation))
return;
Confirmation = Confirmation.Replace("Your Order Confirmation","West Wind Technologies Order Confirmation");
sb = new StringBuilder();
sb.Append("<html><body>");
sb.Append(Confirmation);
sb.Append(" </body></html>");
this.SendConfirmationEmail(sb.ToString());
}This is definitely cool though - because I have a number of pages where part of the page gets generated needs to be reused for multiple purposes. Doing this any other way would be way more complicated since .Net doesn't easily support some sort of mail merge (well it does by using the ASP.Net runtime which would incur a fair amount of overhead).
Thanks. Certainly saved me some time (those damn Writers <g>)...
