At present we do not have support to “Digital Signature in PdfViewerControl”. We do not have any immediate plans to implement this feature. At the planning stage for every release cycle, we review all open features and identify features for implementation based on specific parameters including product vision, technological feasibility, and customer interest.
Based on our present commitments and the above parameters, this feature is expected to be implemented in any of our upcoming release. We will let you know when this feature is implemented.
