When you search for a term, the document is not scrolled. Also when the user inserts a search term and clicks Enter the document is scrolled to the second match instead of the first one.

Does the blazor pdfviewer support password-protected PDF files? I want to read/render an encrypted PDF file. The control should be able to detect that it is password-protected and prompt the user for a password, and finally render the document as expected.

We are trying multiple viewers with the same files in a Blazor server application.
But the other viewers load larger file sizes faster because they load them in modules and when you scroll through the viewer, the others will be loaded.

I didn't see this in the Telerik pdf viewer. Am I correct that this is not standard? And is there a way to make it that way?

Currently we use Telerik WinForm and Blazor PDFViewer components in our products and it is working well. We have a requirement for the PDF redaction and your product does not support that. I would like to make a feature request to add a PDF reaction to the current PDF Viewer. In which the user will have an ability to draw a box around the sensitive content. Ideally would be better if the text content below the image layer is also removed but in the beginning being able to draw box and print would be greatly appropriated.

The ZoomChanged event doesn't fire when the user clicks on the zoom in/out buttons or selects a new zoom level from the ComboBox.

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.

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.

Release 2024 Q2 (May)
I am opening a standard PDF document and it is not properly displayed in the PDF Viewer. For example, you can see the logo and the table borders but the text of the PDF is missing. If you open the same document in a normal Adobe viewer it is fine.

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.

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");
    }
}

Nice job on Telerik, Kendo UI and Test Studio R3 2022!   I like the PDF Viewer UI Controls.  Question: Any plans to add annotations and comments to CLIENT-SIDE ONLY solution i.e. .NET Blazor MAUI libraries similar to this server-side only solution

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?

I would like to have access to the search option of the pdf viewer.
I have an old Asp.net framework site hosting the scanned pages (57.000) of the local newspaper from its start in May 1945 and want to rewrite it in Blazor.

One of the features is that you can search for words on all pages (using SQL Full-text indexing search on a table with all the plain texts to quickly locate the pages containing these words) and when a found page is clicked show the pdf of that page and prefill the searchbox of the pdf viewer to automatic highlight the found words).

This article gives a solution to achieve that in JS, but it would be nice if this could be done from de C# code https://www.telerik.com/forums/open-pdfviewer-with-highlighted-text

Kind regards,

Kees Alderliesten
