Mouse cursor position while dragging

[MuxMux]

Hello,

so the problem is to adjust mouse cursor position while dragging an item from TreeListView control.
I looked through the forum topics but nothing helped. I am using OnDragInitialize event handler 
where I set the DragVisualOffset and DragVisual properties of DragInitializeEventArgs object:

private void OnDragInitialize(object sender, DragInitializeEventArgs e)
{
   recipesDragDropBehavior.DraggedItems = GetDraggedItems(e.Data);

   e.DragVisual = new DragVisual()
   {
      ContentTemplate = Resources["dragComponentTooltipTemplate"] as DataTemplate,
      Content = recipesDragDropBehavior
   };

   var p = new Point
   {
      X = e.RelativeStartPoint.X + 30,
      Y = e.RelativeStartPoint.Y + 30
   };
   e.DragVisualOffset = p;
}

Unfortunately, this does not work.
Any solutions are appreciated.

Thanks in advance.
Mikhail.
