• Node: target node into which data is being dropped
• DataObject: data object containing the data being dropped
• Effect: parameter telling what kind of drop is being performed
• Handled: parameter telling whether the container has handled the event

The Drop event is fired if the control’s client area is the drop target of a drag-and-drop operation.

Use DataObject’s IsFormatAvailable and GetData methods to retrieve the data stored in DataObject. This data was originally filled in the DragSourceFill event and may be stored in any format. (The source control may be either a Table Tree or a Table View control.)

In most cases, you should then set Handled to TRUE. Otherwise the control’s default drag-and-drop processing is executed.

The Effect parameter indicates whether the DataObject should be copied, moved or whether a link should be established.

The Effect parameter is initially set in the DropEnter event-handler, then passed in to Drop event-handler, and subsequently on to the DropComplete event-handler fired by the drop source control.
