How to add custom button in PDF Viewer default toolbar

Platform: ASP.NET MVC |
Control: PdfViewer

PDF Viewer

The ASP.NET MVC PDF Viewer control supports viewing, reviewing, and printing PDF files in ASP.NET MVC applications. The hyperlink and table of contents support provides easy navigation within and outside the PDF files. The form-filling support provides a platform to fill, flatten, save, and print PDF files with AcroForm. PDF files can be reviewed with text markup annotation tools.

Adding custom buttons in PDF Viewer toolbar

PDF Viewer for ASP.NET MVC provides support to add the custom buttons in its default toolbar.

Refer to the following code snippet to add the custom buttons by appending it in the PDF Viewer default toolbar.


$(function () {
            var pdfviewerObj = $("#pdfviewer").data("ejPdfViewer");
            //Hides the download icon from the default toolbar
            pdfviewerObj .showDownloadTool(false);
            var pdfviewerElement = pdfviewerObj .element[0];
            //Gets the default toolbar
            var toolbar = pdfviewerElement.firstElementChild.firstElementChild;
            var role = $(toolbar).attr("role");
            if (role == "toolbar") {
                //Appends the custom button to default toolbar
                $(toolbar).append($('<input type="button" value="Save" style="width:90px;height:30px;margin-top:6px;float:right" onclick=download(); title="Downloads the PDF document"/>'));



Here, HTML button is appended in the default toolbar. You can add your own custom button in place of the added HTML button.
