Acro field values don't show in the PDF VIewer, although they display in the print preview dialog.

This is a regression in version 7.0.0. Version 6.2.0 displays the acro field values as expected.

I would like to be able to control the default zoom level in the PDF viewer. For example, I would like to be able to set it as "Fit to Page".

I want to be able to pinch the document in the PDFViewer and zoom it. Similar to how PDF is fluently zoomed in and out on pinch if opened in a web browser.

When displaying a PDF using the PDFViewer component, I have noticed that, if the PDF being displayed has any website links/hyperlinks in it, the links cannot be clicked. If I download the PDF from the component and open the file, I am able to click the links. Can you add this functionality?

Hello, I like the Telerik PDF Viewer for Blazor, but it's not supporting Table of Contents (TOC) links.  I would like to request this feature so that there are links in the TOC automatically.  I'm using Blazor WebAssembly.

Thank you for considering my request.

I want to have an option for digital signatures with browser-based certificate selection.

For the time being, you can use the following custom approach: Signing PDFs with PdfPRocessing in PdfViewer.

Hello,

we are using the PDFViewer Component. 

The zoom function usually works perfectly, both on mobile and desktop.

But there is one exception.

There is one scenario, where our PO got an crash, when he try to use ANY zoom functionality of the component. 

He is using:

  • a Samsung Galaxy S21 FE 5G
  • Android 14
  • Chrome Browser

Release 7.0.0

When the user scrolls the PDF Viewer down and then opens another PDF file, the new document should display on the first page. Currently, the new file displays scrolled to the page from the previous file and the user must scroll to the top manually.

===

A possible workaround is to scroll the PDF file with JavaScript in the PDF Viewer OnOpen event:

 

@inject IJSRuntime js

<TelerikPdfViewer Data="@PdfSource"
                  Height="600px"
                  OnOpen="@OnPdfViewerOpen"
                  Class="@PdfViewerClass">
</TelerikPdfViewer>

<script suppress-error="BL9992">
    function scrollPdfToTop(selector) {
        var pdfCanvas = document.querySelector(selector);
        if (pdfCanvas) {
            pdfCanvas.scrollTop = 0;
        }
    }
</script>

@code {
    private byte[]? PdfSource { get; set; }

    private string PdfViewerClass { get; set; } = "scrollable-pdf-viewer";

    private async Task OnPdfViewerOpen()
    {
        await js.InvokeVoidAsync("scrollPdfToTop", $".{PdfViewerClass} .k-pdf-viewer-canvas");
    }
}

We're currently working on requiring a Google CASA Security Assessment, as part of this they scanned our site. 

However, the scan found an eval() function in the telerik-blazor.js file:

if(_util.isNodeJS){const worker=eval("require")(this.workerSrc);return worker.WorkerMessageHandler}

 

Is it possible to remove eval() from telerik-blazor.js?

Hello,

we have a bookmark structure with page numbers associated with a PDF and user can navigate throught this structure and jump to particular pages - therefore we need to set the current page of PDF Viewer programmatically.  

Moreover we need to know the count of pages of the viewed PDF file. This can be gotten by using PDF processing API, but it is a bit inconvenient to open the PDF file twice just for this purpose especially in case of big PDF files.

Very thanks,

Miroslav

If you compare the print quality against the Kendo UI jQuery PDF viewer, the quality difference is night and day. We did not investigate what is happening under the hood in both components. However, the same printing dialog appears when printing via both components and both of them are web components, which indicates to us, that this issue is not related to the browser.

We still have some problems with printed pdf quality after the updates in 6.0.0. When pdf is printed using Telerik PDF viewer it seems it gets processed/rasterized and loses quality.

Our use case doesn't seem that too "out of the ordinary", but we have standardized forms that are dynamically rendered using Telerik inputs and a PDF Viewer component and when the user focuses on one of the inputs, the PDF needs to pan/zoom in the general region/area where the value of that input field is located on the PDF.  It's basically to give the user the ability to verify a value that has been OCR'd from the PDF and displayed in the input field.  We have another feature request to add the ability to quickly add a square annotation to the PDF via the API as well because we have to highlight the actual area on the PDF as we pan/zoom.
