public void ImageViewerDragInteractiveModeExample() 
{ 
   _imageViewer.ItemDragDrop += (sender, e) => 
   { 
      _imageViewer.InteractiveModes.BeginUpdate(); 
      e.Effect = DragDropEffects.Copy | DragDropEffects.Move | DragDropEffects.Link; 
      Debug.WriteLine("Format: {0}, Location: {1}, NativeEvent: {2}, Operation: {3}, SourceImageViewer: {4}, SourceItem: {5}, TargetImageViewer: {6}, TargetItem: {7}",  
         e.Format, e.Location, e.NativeEvent, e.Operation, e.SourceImageViewer, e.SourceItem, e.TargetImageViewer, e.TargetItem); 
      _imageViewer.InteractiveModes.EndUpdate(); 
      e.Abort = true; 
   }; 
   _imageViewer.InteractiveModes.BeginUpdate(); 
   ImageViewerDragInteractiveMode dragMode = new ImageViewerDragInteractiveMode(); 
   dragMode.Format = RasterImage.RasterImageDataFormat; 
   dragMode.TargetImageViewerMode = ImageViewerDragTargetMode.All; 
   dragMode.AllowedEffects = DragDropEffects.Copy | DragDropEffects.Move | DragDropEffects.Link; 
   _imageViewer.InteractiveModes.Add(dragMode); 
   _imageViewer.InteractiveModes.EndUpdate();
