⛔ DEPRECATED. This example demonstrates how to use the PDF Document API to read comments (sticky notes) from a PDF document. Retrieved comments' data is displayed in an AccordionControl next to the PDF document loaded into WinForms PDF Viewer.
Starting from v20.2, the DevExpress PDF Document API and PDF Viewer support sticky notes (comments) out of the box. The Comments Pane in the PDF Viewer allows you to add, edit, and remove sticky notes in the UI. Refer to the following blog for more information: PDF – Sticky Notes and Comments.
