Enables a Microsoft UI Automation element to describe itself as an element that can be dragged as part of a drag-and-drop operation. Implement this interface in order to support the capabilities that an automation client requests with a AutomationPeer.GetPattern call and PatternInterface.Drag.

Remarks
The Drag control pattern is used to support draggable controls, or controls with draggable items. For more info on what this pattern is for, see Drag Control Pattern.
IDragProvider is implemented by the existing Windows Runtime automation peers for a ListView item (ListViewItemAutomationPeer) or GridView item (GridViewItemAutomationPeer). This supports the Windows Runtime scenario of dragging list items so that they can be reordered. The peer for the host view of the items (ListViewAutomationPeer or GridViewAutomationPeer) support the IDropTargetProvider pattern.
Use DragPatternIdentifiers if you want to reference the IDragProvider pattern properties from control code when you fire automation events or call AutomationPeer.RaisePropertyChangedEvent.
