When the user begins to drag an item from the ListView or TreeView controls, they raise an ItemDrag event. This class encapsulates the Item that is being dragged and the Button that initiated the drag.

public class ItemDragEventArgs : EventArgs {
// Public Constructors
   public ItemDragEventArgs(MouseButtons button);
   public ItemDragEventArgs(MouseButtons button, object item);
// Public Instance Properties
   public MouseButtons Button{get; }
   public object Item{get; }
}
