Details

The _getMaxrow method returns the maximum number of rows for which a data table can be scrolled down. A negative value indicates that the number of rows is dynamic. The ratio of this value to the number of visible rows (see the _getVisrow method in this class) determines the size of the thumb in the vertical scroll bar.
