Thank you for contacting Telerik Support.
Unfortunately Test Studio cannot read and/or verify against the contents of a PDF file loaded in the browser (using PDF Viewer or otherwise), as it does not have a DOM structure like a traditional web page. The only workaround I can suggest (other than a manual step) is that you store that information in a file type such as XLS, XML, CSV, or a SQL database, then you can use the Data Driving
Please let me know whether you have any further questions.
