Virtual list control can be used as a normal one except that no operations
which can take time proportional to the number of items in the control happen
-- this is required to allow having a practically infinite number of items.

implementation for report mode, and uses a generic implementation for other
modes. You can use the generic implementation for report mode as well by setting
