Hi Roman,
Greetings from syncfusion support.
At present, we do not have support for “Enable or disable the toolbar dynamically using SfPdfViewer”. 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 our 2020 Volume 2 main release. We will let you know when this feature is implemented.
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,
Regards,
Jhansi Priya Ramesh
