Hi Andreas,
At present, we do not support viewing the PDF document pages in a single page mode. Also, we do not have any immediate plan for implementing this feature and it will be included in any of our upcoming release. However, we could not reproduce the issue “Out of memory exception while loading the large PDF document”, we have implemented memory optimization in our control to handle large document, and we do on demand rendering to maintain memory usage. Can you please provide us the input document, so that it will be easy for us to investigate further on this? If the document is not confidential, you can share it here, or else create a Direct Trac incident with your Syncfusion account and share the PDF document there. It will be more helpful for us to work on the reported problem.
With Regards,
Gayathri R
