Why doesn't itext convert my page to pdf?

I am using this to convert the html to pdf but it does nothing. No error or exception. I debugged and it has the html content and even shows on page but not downloading. I am loading HTML content into hidden field from database and assigning to literal control from backend and i checked it shows the value.

Code:

private MemoryStream Export(string html="")
    {
        ltr.Text = hdnDescription.Value;
        html = ltr.Text;

        MemoryStream msOutput = new MemoryStream();
        TextReader reader = new StringReader(html);

        // step 1: creation of a document-object
        Document document = new Document(PageSize.A4, 30, 30, 30, 30);

        // step 2:
        // we create a writer that listens to the document
        // and directs a XML-stream to a file
        PdfWriter writer = PdfWriter.GetInstance(document, msOutput);

        // step 3: we create a worker parse the document
        HTMLWorker worker = new HTMLWorker(document);

        // step 4: we open document and start the worker on the document
        document.Open();
        worker.StartDocument();

        // step 5: parse the html into the document
        worker.Parse(reader);

        // step 6: close the document and the worker
        worker.EndDocument();
        worker.Close();
        document.Close();

        return msOutput;
    }

First, HTMLWorker was superseded by XMLWorker, which has just been superseded by pdfHTML. Being behind this many versions will not help your document - workflow.

Second, iText only converts static HTML. ASP pages are not considered static content.
