Thats what I did and it is creating the pdf as required

protected void btnExport_Click(object sender, EventArgs e)
    {
        var document = new Document(PageSize.A4, 50, 50, 25, 25);
        var output = new FileStream(@"C:\Temp\PersonDetail.pdf", FileMode.Create);
        var writer = PdfWriter.GetInstance(document, output);
        document.Open();


        StringBuilder sb = new StringBuilder();
        StringWriter tw = new StringWriter(sb);
        HtmlTextWriter hw = new HtmlTextWriter(tw);
        pnlPerson.RenderControl(hw);
        var html = sb.ToString();
        var parsedHtmlElements = HTMLWorker.ParseToList(new StringReader(html), null);

        // Enumerate the elements, adding each one to the Document...
        foreach (var htmlElement in parsedHtmlElements)
            document.Add(htmlElement as IElement);

        document.Close();

    }

Please read this nice article by Scott Mitchell at https://web.archive.org/web/20211020001758/https://www.4guysfromrolla.com/articles/030911-1.aspx and decide what is best for you. As suggested by the author in this article, parsing the HTML and adding it into the PDF has limited support and may not work for complex HTML structures.

Let me know if it helps.
