When we print any large (10-500 pages) document  using WPF PdfViewer the UI becomes unresponsive. For the document with 100 pages it might take minutes. Are there any solutions for PdfViewer that improve User Experience printing large documents? To be more specific, is there a way to:

Show the progress bar with number of pages completed and left or % done with "Cancel" printing job button

OR

any other solution that would help to implement asynchronous printing?

Hello Mike,

Thank you for contacting us.

I am attaching a sample project showing how to extend the default PrintDialog in order to allow async printing operation. The project prints a sample PDF file with RadPdfViewer and you may test with UpdateUI button to see that the UI is responsive during the printing process.

I hope this is helpful.

Regards,
