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

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.

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");
    }
}

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

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.

===

TELERIK edit: This public item originally concerned to all Acro fields. We fixed the problem for editable Acro fields, while the fix for readonly ones can be tracked at PDF Viewer does not display readonly Acro fields

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

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?

When printing a PDF file with the PDF Viewer, there is an "about:blank" title at the top and bottom of the paper sheet. I would like to set a contextual value of my own, or remove this "about:blank" altogether.
