Unit:  SDL_replist  Class:  TRLData  Declaration:  property NrOfRows:
longint; 
The property NrOfRows specifies the number of rows of the TRLData structure. Increasing the number of rows preserves all information in the list view, while decreasing its number of rows destroys the information contained in the removed (bottom) rows.
Hint 1: 
Increasing the number of rows requires considerably more computing time than decreasing it. In order to overcome this problem, the property AllocRowsBy of the property Strings should be increased. 
Hint 2: 
Reducing the number of rows of a sorted report list will corrupt the data unless the method Strings.CommitSorting is called before changing the number of rows. 
Hint 3: 
In the Light Edition the max. number of cells of the data table is restricted to 2000 (i.e. the product of NrOfRows times NrOfColumns must not exceed 2000).
