Partially Convert of a HTML Page to PDF

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.

        [HttpPost]
        public ActionResult ConvertHtmlToPdf(IFormCollection collection)
        {
            // Create a HTML to PDF converter object with default settings
            HtmlToPdfConverter htmlToPdfConverter = new HtmlToPdfConverter();

            // 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 (collection["ConvertElement"] == "convertElementRadioButton")
            {

                string htmlElementSelector = collection["htmlElementSelectorTextBox"];
                htmlToPdfConverter.RenderedHtmlElementSelector = htmlElementSelector;
            }

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

            // Send the PDF file to browser
