Hello colinmhart,
Thanks for your sharing.
You purchased the license of our Spire.PDFViewer for Forms, it can not be used for Asp program, you need to use the license of Spire.PDFViewer for Asp. These are two products. Do you just need the license of Spire.PDFViewer for Asp? If you buy wrong, we can change the corresponding product license for you. Look forward to your feedback.
Besides, for your previous and next buttons, I found that your code used "PdfDocumentViewer1. NextPage ()", please use the "pdfDocumentViewer1. NextPage ()" with lowercase. If you have any further questions, please feel free to contact us.
Sincerely
Simple
