Event Data

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

Property	Description
Allowed	Gets or sets a value that indicates whether the current operation is allowed.
AnnObject	Gets the AnnObject that is being dragged.
CanDrop	Gets a value that indicates whether the object(s) being dragged can be dropped on the target container.
Operation	Gets the current drag and drop operation.
OperationContainer	Gets the current container for this drag and drop operation.
SourceContainer	Gets the source annotation container.
TargetContainer	Gets the source annotation container.

Remarks

This event occurs during editing of an object when multiple containers are used and an object is being dragged out of one container. The default behavior will move the object from the source to the target container (if any). Override this method to provide custom behavior if required.

This event will trigger only if the value of EnableDragDrop is true.

EnablePartialDrop controls the behavior when an object is dragged then dropped while its boundary is not completely enclosed in any container.
