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,

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?

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.

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.

Set the PdfViewer document (data) value to null. As a result, an endless loader will appear.

A possible workaround for the time being is to re-initialize the component after clearing the file: https://blazorrepl.telerik.com/cHYwQola24zzBOAd02.

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
