Event Data

The event handler receives an argument of type MedicalViewerAnnotationCreatedEventArgs containing data related to this event. The following MedicalViewerAnnotationCreatedEventArgs properties provide information specific to this event.

Property	Description
AnnotationType	Gets an enumerated value that indicates which type of annotation was created.
CellIndex	Gets the value that indicates the index of the cell that has the annotation that was created. This value is only valid if the cell is add to the MedicalViewer.
Object	Gets the created annotation object.
SubCellIndex	Gets the value that indicates the index of the sub-cell that has the annotation that was created.
