The initialPageSize property defines the initial page size of a list element.

Some list containers, such as a resizable ScrollGrid container, displays by default a single row, if no other elements in the form layout forces the container size implicitly. For these containers, the initialPageSize property can be used to specify a default initial number of rows to be displayed.

For a ScrollGrid, this property only displays when the wantFixedPageSize property is not selected.

For more information, see the INITIALPAGESIZE attribute topic in the Genero Business Development Language User Guide.
