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.

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.

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.

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;
    }
}

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.

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.

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.

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

The loading animation is visible only when a user opens a file from the Toolbar of the component. When programmatically opening a file, the loader is not shown.

I want to set the Data of a PDFViewer from the OnRowClick event handler. If I use the ReadAllBytesAsync() method, the PDF viewer does not render the PDF document. I need to use the synchronous version (ReadAllBytes) to make this work.

Please implement UI virtualization for the PDF Viewer, so that it can render large PDF files quickly. We are talking about documents with hundreds of pages and even more.

Open the PDF Viewer component online demo and click the download button:

Expected - the PDF must be downloaded.

Current - the file is not downloaded.

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
