TIWCGJQGridOptions.RowList Property
An array to construct a select box element in the pager in which we can change the number of the visible rows. When changed during the execution, this parameter replaces the rowNum parameter that is passed to the url. If the array is empty the element does not appear in the pager. Typical you can set this like [10,20,30]. If the rowNum parameter is set to 30 then the selected value in the select box is 30.
