Annotations are floating text bars or images to call attention to specific items or values or to add notes and special instructions directly to the reports. Annotations added via the viewer's toolbar are temporary and are destroyed when the report closes.
These annotations are accessible through the Annotation button present on the Viewer toolbar which is hidden by default. You can make the Annotations toolbar visible by setting the AnnotationToolbarVisible Property to True in the viewer's properties window.
