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.

 

 

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.

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

Expected - the PDF must be downloaded.

Current - the file is not downloaded.

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.
