This event is raised when the GoToolManager or the GoToolDragging tool notices that a mouse move causes a change in the current document object that the mouse is over. The GoObjectEnterLeaveEventArgs indicates the object that the mouse had been over, and the object that it is now over. Either object may be null, indicating that it had been or now is over the background of this view.
Because drag-and-drop is a modal operation, an external drag-and-drop from a different Control will not normally raise any ObjectEnterLeave events. However, you may be able to get such events if you set ExternalDragDropsOnEnter to true and DragsRealtime to true, since then a drag enter may cause some GoObjects to be added to the document by OnDragEnter and DoExternalDrop and then to be dragged around by the GoToolDragging tool.
