Open a PDF file in the PDF Viewer. Tap the magnifier icon to initiate the search. Start typing, the component freezes.

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.

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.

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.

Hallo,

i want to Render PDF Files with the PDF Viewer Component.

The Data of the PDF is already fetched from the API when the PDF-Viewer starts Rendering the Loading animation appears and freezes.

After a few Seconds the PDF will be Rendered.

The size of the PDF File is about 5MB.

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.

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 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.

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".

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.

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.

Adding the ability to fill in a PDF online in the PDF Viewer would open a lot of opportunity to the library.

The ability to fill-out, sign, and date would be great with a save callback, so it can be pushed to an API.

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.

An event that will fire when the PDF is fully loaded in the component. I want to use that event to call the PDFViewerReference.Print() method.

This request is for allowing to open other document types in PDF Viewer - for example, Word, Excel. The functionality will target viewing only and not editing.

The steps to handle the scenario will be the following:
  1. Handle the OnOpen event to get the file bytes
  2. Use the appropriate format provider of the RadSpreadProcessing library to import the Word/Excel file
  3. Export the file with the PdfFormatProvider
  4. Pass the converted file to the PDF Viewer to display it

Note: We've registered a bug with this solution. The PDF Viewer does not open other types of documents from the FileSelect in the Toolbar, they can be opened only on initialization of the component. Currently, the bug is in our backlog. Once fixed, the above-listed solution can be used to configure the PDF Viewer for viewing other document types. A knowledge base resource will be published on the matter.

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?

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:

<TelerikButton OnClick="@OnOpenToggle">Toggle Open Buttons</TelerikButton>

<TelerikPdfViewer Data="@PdfSource"
                  Class="@HideOpenClass"
                  Height="400px" />

<style>
    .hide-open .k-blank-page,
    .hide-open .k-button:has(.k-i-folder-open) {
        display: none;
    }
</style>

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

    private string HideOpenClass { get; set; } = string.Empty;

    private async Task OnOpenToggle()
    {
        string _hideOpenClass = "hide-open";

        HideOpenClass = HideOpenClass == _hideOpenClass ? string.Empty : _hideOpenClass;
    }
}
