Page break in birt 4.3.1

Migrateduser

<p>I have a workorder report that has too much information on it, some come from the database like task workorders etc. Some are just data-grids with labels. Is there a way that i can force this report to have a page break after a certain number of rows e.g 20 rows. I don't want to have a page break after a certain datagrid. I want to count the number of rows that fit in a page and then have a page break there. Please help. Thanks.</p>
