Hi Rajesh,
Thank you for contacting Syncfusion support.
Currently, we do not have support to rotate the PDF pages using PDF Viewer. We have added it to our feature request list. But, we don’t have any immediate plans to implement this feature. At the planning stage for every release cycle, we review all open features. We will implement this feature in any of our upcoming releases.
Now, you can track the status through the below link.
Regards,
Akshaya
