Partially Convert of a HTML Page to PDF

EVO PDF Client for .NET Documentation

Sometimes is necessary to convert only a part of a HTML document like a table or div. With EVO HTML to PDF converter this is perfectly possible. The HTML element to be rendered to PDF is given by the HtmlToPdfConverterRenderedHtmlElementSelector property.

The RenderedHtmlElementSelector property can be set with any CSS selector. Please be aware that the CSS selectors are case sensitive and if many HTML elements are selected then only the first one will be actually converted.

Copy

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

    // Create a HTML to PDF converter object
    HtmlToPdfConverter htmlToPdfConverter = null;
    if (radioButtonUseTcpService.Checked)
        htmlToPdfConverter = new HtmlToPdfConverter(serverIP, serverPort);
    else
        htmlToPdfConverter = new HtmlToPdfConverter(true, textBoxWebServiceUrl.Text);

    // Set optional service password
    if (textBoxServicePassword.Text.Length > 0)
        htmlToPdfConverter.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
    htmlToPdfConverter.LicenseKey = "4W9+bn19bn5ue2B+bn1/YH98YHd3d3c=";

    // Set an adddional delay in seconds to wait for JavaScript or AJAX calls after page load completed
    // Set this property to 0 if you don't need to wait for such asynchcronous operations to finish
    htmlToPdfConverter.ConversionDelay = 2;

    if (convertElementRadioButton.Checked)
    {
        // Select the HTML element to convert
        string htmlElementSelector = htmlElementSelectorTextBox.Text;
        htmlToPdfConverter.RenderedHtmlElementSelector = htmlElementSelector;
    }

    // Convert the HTML page to a PDF document in a memory buffer
    byte[] outPdfBuffer = htmlToPdfConverter.ConvertUrl(urlTextBox.Text);
