If the PdfViewer is initialized with a default document, the display performance of this document will be a lot worse, compared to PDF documents that are loaded programmatically after the component is already on the web page.

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.

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");
    }
}

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.
