protected void createPdf()
{
    // Get the server IP and port
    String serverIP = textBoxServerIP.Text;
    uint serverPort = uint.Parse(textBoxServerPort.Text);

    // Create a PDF document
    Document pdfDocument = null;
    if (radioButtonUseTcpService.Checked)
        pdfDocument = new Document(serverIP, serverPort);
    else
        pdfDocument = new Document(true, textBoxWebServiceUrl.Text);

    // Set optional service password
    if (textBoxServicePassword.Text.Length > 0)
        pdfDocument.ServicePassword = textBoxServicePassword.Text;

    // Set license key received after purchase to use the converter in licensed mode
    // Leave it not set to use the converter in demo mode
    pdfDocument.LicenseKey = "4W9+bn19bn5ue2B+bn1/YH98YHd3d3c=";

    // Add a PDF page to PDF document
    PdfPage pdfPage = pdfDocument.AddPage();

    // Create the document footer template
    pdfDocument.AddFooterTemplate(50);

    // ----- Add HTML with Page Numbering to Footer -----

    // Create a variable HTML element with page numbering
    string htmlStringWithPageNumbers = htmlWithPageNumbersTextBox.Text;
    string baseUrl = baseUrlTextBox.Text;
    HtmlToPdfVariableElement footerHtmlWithPageNumbers = new HtmlToPdfVariableElement(htmlStringWithPageNumbers, baseUrl);

    // Set the HTML element to fit the container height
    footerHtmlWithPageNumbers.FitHeight = true;

    // Add variable HTML element with page numbering to footer
    pdfDocument.Footer.AddElement(footerHtmlWithPageNumbers);

    // Optionally draw a line at the top of the footer
    if (drawFooterLineCheckBox.Checked)
    {
        float footerWidth = pdfDocument.GetPage(0).PageSize.Width;

        // Create a line element for the top of the footer
        LineElement footerLine = new LineElement(0, 0, footerWidth, 0);

        // Set line color
        footerLine.ForeColor = RgbColor.Gray;

        // Add line element to the bottom of the footer
        pdfDocument.Footer.AddElement(footerLine);
    }

    // Create a HTML to PDF element to add to document
    HtmlToPdfElement htmlToPdfElement = new HtmlToPdfElement(0, 0, urlTextBox.Text);

    // Optionally set a delay before conversion to allow asynchonous scripts to finish
    htmlToPdfElement.ConversionDelay = 2;

    // Optionally add a space between footer and the page body
    // Leave this option not set for no spacing
    htmlToPdfElement.BottomSpacing = float.Parse(footerSpacingTextBox.Text);

    // Add the HTML to PDF element to document
    // This will raise the PrepareRenderPdfPageEvent event where the header and footer visibilit per page can be changed
    pdfPage.AddElement(htmlToPdfElement);

    // Save the PDF document in a memory buffer
    byte[] outPdfBuffer = pdfDocument.Save();

    // Write the memory buffer in a PDF file// Send the PDF as response to browser

    // Set response content type
    Response.AddHeader("Content-Type", "application/pdf");

    // Instruct the browser to open the PDF file as an attachment or inline
    Response.AddHeader("Content-Disposition", String.Format("attachment; filename=Page_Numbers_in_HTML.pdf; size={0}", outPdfBuffer.Length.ToString()));

    // Write the PDF document buffer to HTTP response
    Response.BinaryWrite(outPdfBuffer);

    // End the HTTP response and stop the current page processing
    Response.End();
