EVO HTML to PDF Converter

Select in API the HTML Elements to Hide

EVO HTML to PDF Converter for .NET Documentation

EVO HTML to PDF Converter API allows you select the HTML elements to exclude from rendering to PDF. The converter does not reflow the HTML content when you exclude an element from rendering and the place where the element would be normally rendered remains blank. If you want to reflow the HTML content when the HTML element is hidden, you have to set display:none style for HTML element, eventually creating two separate stylesheets for screen and for print.

The selectors of the HTML elements to hide in the generated PDF document can be set in the HtmlToPdfConverterHiddenHtmlElementsSelectors property.

Code Sample - Select in API the HTML Elements to Hide
Copy
protected void convertToPdfButton_Click(object sender, EventArgs e)
{
    // 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;

    // Select the HTML elements for which to retrieve location and other information from HTML document
    if (hideSelectedElementsCheckBox.Checked)
        htmlToPdfConverter.HiddenHtmlElementsSelectors = new string[] { htmlElementsSelectorTextBox.Text };

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

    // 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=Select_in_API_HTML_Elements_to_Hide.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();
