Use whole pixels when auto-setting the datagrid height.
Review Request #7209 — Created April 15, 2015 and submitted
When calculating the desired datagrid height, based on the page height, the value wasn't always an integer. This led to styling problems. We now round up to the nearest full integer value when setting the height.
Saw the value went from being a number like 461.492818px to 462px.
