Hello,
I have an 8mb PDF files that I need to be able to search, however when I click on the search tool the entire page starts responding.
This issue happens in your hosted demo. It seems to come as a result of images in the PDF.
What do I need to do to have it work properly?
Thanks,
Greg
Hi,
Is a thumbnail/page viewer in discussion? It would be a real advantage to be able to see thumbs of pages alongside the page viewer.
An example using a different sdk is shown below.

Both Chrome and Firefox now have native PDF viewer support including the ability to display and navigate bookmarks within the document. Kendo’s control doesn’t have this functionality, but it’s possible to implement since PDF.js does and the Kendo control supports PDF.js rendering.
We’d really like to have a common UI for viewing documents within our web application, but we’re currently forced to render PDFs natively for Chrome and Firefox and with limited bookmark functionality for Internet Explorer by way of partial bookmark functionality we’ve implemented on top of the Kendo control.
Allow bookmarks to be set in the PDFViewer’s configuration during initialization, and then add a method to allow them to be scrolled-to by id. The bookmarks would simply be y-coordinate/page number pairs. It’d also be nice if the viewer could read the bookmarks directly, but not entirely necessary with PDF.js rendering since they can be read from PDF.js
Ideally, you could also expose the raw PDF.js document object used by the PDFViewer so that it could be used instead.
The print functionality does not work when using chrome on android and safari on iphone.
I tested at the url https://demos.telerik.com/kendo-ui/pdfviewer/index
Please advise.
Bug report
Currently the result of PDFViewer printing is affected by PDFViewer scale option. When scale is less than 200%, the letters in the printed PDF appear blurred.
Reproduction of the problem
- Go to https://demos.telerik.com/kendo-ui/pdfviewer/index
- Set scale option to 100%
- Print to PDF using "Microsoft Print to PDF" printer. (The final result is the same compared to actual printing to a physical printer)
- For consistency set the following print options, e.g. in Chrome:
- Paper size: A4
- Pages per sheet: 1
- Margins: None
- Scale: Default
Current behavior
Text in printed PDF file is blurred
Expected/desired behavior
Text in printed PDF file is clear.
NOTE: Clear text may be achieved if PDFViewer scale option is set to 400% on the demo before printing.
Environment
- Kendo UI version: 2019.3.1023
- Browser: all

I have experience with OpenText Brava Enterprise. I've had the chance to integrate their Viewer in our in-house document management system. This viewer opens up to 100 file formats and allows to add/remove/edit annotations on files and saves these annotations as a separate layer on top of the file. So next time you open the same file to view, you can load the annotations (via API) calls and place the layer of annotations on top.
I was hoping I would see the same thing with Telerik PDF Viewer (and I am aware this works only for PDF). To allow the user to add a Text comment, Shapes, Stamps, Image, PDF Bookmark, etc.
