Bug report
PDFViewer focuses zoom input when the user clicks on zoom-in icon in Safari on iPhone and iPad
Reproduction of the problem
Dojo: https://dojo.telerik.com/AvOZeriz
Click on zoom in icon
Expected/desired behavior
Focus shall remain on the zoom in icon
Environment
Kendo UI version: [all]
Browser: [Safari]
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.
Currently, when the PDFViewer is used with the latest pdf.js version 4.0.379 an error is thrown in the browser console. (Uncaught (in promise) Error: No "textContentSource" parameter specified.)
You can test the behavior in the Dojo linked here - https://dojo.telerik.com/@NeliKondova/eBUYEDAb. Run the example and wait for the pdf file to be loaded, then check the browser console.
The latest Kendo version is compatible with pdf.js version 3.11.174. However, I would like the Kendo UI for jQuery to be compatible with pdf.js 4.x to avoid such misbehaviors.
Hi Team,
I understand at the moment there is a limitation to exporting Hierarchical Grids to PDF. I would like to request in the future a way to somehow overcome this.
Thank you!
The Actual Width option in the PDFViewer does not work as expected. The width rendered in the component does not match the actual width of the file.
Test scenario: a file that has 11.69 inches width ( approx. 1122 pixels ) is displayed with ~840px width.
The page width rendered from the Actual Width feature does not match the actual file width
The page width from the Actual Width option should match the actual page size of the file.
Go to:
Demo of core features in jQuery PDFViewer widget | Kendo UI for jQuery (telerik.com). Note that pdf has 3 pages.
In the pdf viewer component demo select the printer icon and a print preview window opens. When the print preview window opens, note that the window indicates that there are 5 pages to print in the print preview. One page is added before the pdf pages and one after. This happens regardless of the printer selected.
Expected behavior: only 3 pages of the pdf should show in the print preview window.
Hi,

Unable to print PDFViewer's PDF on Safari
Regression since 2022.2.802 , most probably related to the following fix in that release - #6923
The Print Options window is loaded, but PDF pages are not shown in the Print preview. PDF pages content is not present in the saved PDF, if we save the printed content to file.
PDF pages are shown in the print preview window of Safari and can be saved to PDF
Working version 2022.2.621 - https://runner.telerik.io/fullscreen/abePoXEy
When the PDFViewer is created and a file is loaded using the fromFile method a new thread will be created. That thread remains in memory and doesn't get destroyed when the entire widget is destroyed.
$("#pdfViewer").data("kendoPDFViewer").destroy(); $("#pdfViewer").empty();
That created thread remains in memory and doesn't get destroyed.
The thread should get destroyed when the widget is destroyed.
###Workaround
A possible workaround:
kendoPDFViewer.processor.pdf.loadingTask.destroy();
The issue should be additionally researched as there are some leftovers in the JS Heap even when the workaround is used.
In PDFViewer, underlines increase size when zooming in/out.
The underlines increase their size.
The underlines should remain the same.
Dear Team,
As like in other frameworks (https://pspdfkit.com/) we should have the in built option to rotate the PDF pages using Kendo UI PDFViewer widget.

The PDF.js library supports sending xhr with credentials. Please expose this option so credentials can be specified.
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
