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 a user invokes a Search tool, their intention is to directly write a text to search, therefore the edit for the search text should be focused immediately. In the current implementation, users have to manually focus the edit all the time, which is really inconvenient.

I need access to the file the user has open. Also, if the file is changed, like with annotations, I want to access those changes too.

I'm wondering if there is any plan to implement a URL as an option for loading in a PDF.  I want to be able to display PDFs that are hosted in a Sharepoint drive by URL without having to download a PDF into memory every time.  I know there are viewers that can do this, but I'm just wondering if I'm missing something with Telerik, or if I need to go with a different solution.

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.

Please expose a parameter to show or hide the "Select files..." button inside the empty PDF Viewer.

Currently, a possible workaround is to use CSS. Additionally, you may configure the Toolbar to not include the "Open" tool.

<style>
    .no-open .k-blank-page {
        display: none;
    }

    /* Use these selectors if you want to separately target the upload or the dropzone */
    /* .no-open .k-external-dropzone,
    .no-open .k-upload{
        display: none;
    } */
</style>

<TelerikPdfViewer Data="@PdfSource"
                  OnOpen="@OnPdfOpen"
                  Height="600px"
                  Class="no-open">
    <PdfViewerToolBar>
        <PdfViewerToolBarDownloadTool />
        <PdfViewerToolBarPrintTool />

        <PdfViewerToolBarSpacer />

        <PdfViewerToolBarPagerTool />

        <PdfViewerToolBarSpacer />

        <PdfViewerToolBarZoomTool />
        <PdfViewerToolBarSelectionTool />
        <PdfViewerToolBarSearchTool />
        <PdfViewerToolBarAnnotationsTool />
    </PdfViewerToolBar>
</TelerikPdfViewer>

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

    private bool LoaderVisible { get; set; }

    private async Task OnPdfOpen(PdfViewerOpenEventArgs args)
    {
        // Cancel the event for additional precaution in case someone bypasses the CSS and forces the page to show the button and the dropzone.
        args.IsCancelled = true;
    }
}

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.

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 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

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 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

Pdf viewer should display form fields like Text fields, check boxes, etc and allow users to type in fields.  Also support form field calculations.

Once populated, allow client side save to a file blob so that the data could be posted to a server or really whatever the dev wanted to do with it.
