Is _itemBiz.DeleteItemsByOrderKey a method on a business object? Why not use the same methodology for deleting the actual order as well. Also, you should verify the line items were deleted before attempting to delete the actual order. What is _dtOrderSearch? If this is a grid, then that explains why you are seeing the order disappear in the grid but not deleted in the data.
