Currently, if a PDFViewer is opened on a mobile device and we use two fingers to zoom its content, the file is zoomed but the more we zoom it, the blurrier its content becomes. The reason for this is the fact that when we use "pinch-zoom" to zoom the PDF file(in a PDFViewer) it is zoomed using the browser's zoom functionality and not the functionality provided by the PDFViewer component. 

It will be a very useful feature if the built-in PDFViewer zoom functionality is used when the user zooms content with two fingers, on a mobile device

The current implementation of the Kendo PDFViewer depends on pdf.js, so the following should be taken into account:

Bug report

The PDFViewer HTML helper incorrectly serializes the passed to its "File" configuration URL, when the URL has an ampersand(&) sign in it. In the output of the HTML helper, the ampersand is changed with its ASCII code - "\u0026"

  • The issue is reproducible both in the UI for ASP.NET Core and UI for ASP.NET MVC suites.

Reproduction of the problem

  1. Create an ASP.NET Core or MVC project
  2. Paste the below code in it and run it
    @(Html.Kendo().PDFViewer() .Name("pdfviewer-test") .PdfjsProcessing(pdf => pdf .File("https://myrandomcomain.com/api/MyFolder/GetPDF?reference=xxxxxxxx&param1=0&param2=100&contentType=application/pdf") ) .Height(400) )
  3. View the source of the opened page and see the generated Javascript code

Current behavior

The generated code is:

Expected/desired behavior

The expected result is


  • Kendo UI version: 2020.1.219
  • jQuery version: x.y
  • Browser: [all]

1. Allow the elastic behavior of the PDFViewer's mobile scroller to be disabled. Currently, when scrolling to the top or to the bottom, the document jumps and then immediately re-adjusts its position under the widget's header/bottom border.

2. Add the ability to manually scroll the document up/down with mousedown.

3. Add keyboard scrolling support.
