I am using the latest version of asp.net ajax controls 2021.3.914.45.

The pdf loads fine (200 pg. document) but when I try to search or print it takes forever.

Is there any way to make it quicker?

It works Ok on smaller pdf files.

Hello John,

The search issue is a known problem in the underlying Kendo UI PdfViewer widget and you can vote for and follow it here:

A possible workaround you can consider until the issue is fixed is to implement the pure PDF.js viewer as a replacement as demonstrated in the blog post below:
