Hi Sheldon, 


Thank you for contacting Syncfusion support. 

Currently, in PdfViewer we do not have support to “Track the events of Form field interaction” and we do not have any immediate plans to implement these features. 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 our 2020 Volume 2 main release.  
  
Disclaimer: The date for the feature implementation is tentative and not a commitment on our parts.       
  
You can now track the status of this feature request here,

 Please let us know if any further assistance required.
