Hi Robert,
Thank you for contacting Syncfusion support.
Regarding “For the selected text, display the context menu with actions, Change the color for the selected word and convert my pdf document into a word document?”:
At present we do not support highlighting, underlining and striking through the selected text by using the context menu. Also, we do not support changing the selected text color in the PDF document and convert the PDF document into Word document using PdfViewerControl. We have already logged these as a feature request in our database and we do not have any immediate plans to implement these features. We will consider to implement these features in any of our upcoming releases. We will update you when these features has been implemented.
Regards,
Priyanga.E
