What happens if you remove 'Response.ContentType = "application/pdf"' but keep 'Response.ContentType = "text/html"'?

Or try something like this:

protected override void Render(HtmlTextWriter writer)
{
   var strWr = new StringWriter();
   var htmlWr = new HtmlTextWriter(strWr);
   base.Render(htmlWr);
   htmlWr.Flush();
   var htmlToPdf = new HtmlToPdfConverter();
   htmlToPdf.GeneratePdf(strWr.ToString(), null, @"c:\AlertAttachments\example2.pdf");

   base.Render(writer);
   Response.ContentType = "text/html";
}
