public: event EventHandler<MedicalViewerAnnotationCreatedEventArgs^>^ AnnotationCreated
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. |
