Event Data

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

Property	Description
Container	Gets the annotation container that contains the annotation object that is being created, clicked under the run time mode or edited.
Designer	Gets the newly created designer.
Object	Gets the object that is being created, clicked under the run time mode, or edited.
SubCellIndex	Gets the sub-cell index of the cell that contains the container of the object that is being created, clicked under the run time mode, or edited.
Type	Gets the type of the newly created designer.

This delegate occurs when the user:

starts creating a new annotation object using the Medical Viewer actions. For more information, refer to AddAction.
