static DragAdorner WPFCustomControls::DragAdorner::AttachDragAdorner	(	FrameworkElement	element,
		double	opacity,
		bool	useDesiredSize
	)		[inline, static]

Used as the entry point to this adorner.

Call this method with an element that you want to see dragged across the surface of its owning window. Wrap the DragAdorner in a using clause that contains the DoDragDrop call, and the adorner shall be removed and disposed of as expected.

For this to work correctly, the window needs to be marked AllowDrop=true.

Parameters:

element	The element that should be dragged (doesn't need to be the triggering element.) Note that the element is used as the stencil for a VisualBrush, so nothing happens to the element itself.
opacity	Opacity of dragging element.
useDesiredSize	Whether to use the element's Desired size or Actual size.

Returns:

The adorner created for this drag.
