Thank you for sending us the PDF document.
Opening the document with notepad I can see that there is invalid cross-reference table in it. On row number 3194 the start index of the table is 1 (instead of its correct zero value). Although Adobe Reader handles this kind of invalid documents, Telerik's PDF viewer does not display them. Changing the value of the start index from 1 to 0 fixes the issue and the modified document is opened successfully in PdfViewer.
I am attaching the modified version of the document with the described correction. I am also attaching a screenshot showing the difference between the two documents.
If you have further questions or concerns do not hesitate to contact us again.
