The StartDrag event is fired when the a drag and drop process commences It is the first event in the drag and drop process - StartDrag, DragOver, DragDrop and EndDrag StartDrag is used to populate the generic payload object with whatever information is being transferred and to configure the drag cursor via the DragList parameter StartDrag will only fire if the the control being dragged has a DragStyle property of Automatic or Aggregated. The Payload parameter provides a generic space where you can store information about the nature of the data being dragged. The Payload instance will be available on every one of the four drag and drop events.
In this example, the customerlist is being dragged from. A Customer data object is stored as the RelatedReference of list item, and this is used as the payload.
