Results grid

After running many widgets (Select Events, QC), a results grid opens containing event results. By default, the results grid opens at the bottom of the page; however, this is configurable. You can directly edit event records in the results grid. The results grid contains four tools that can help you edit event data: Zoom To (selected events), Select All, Save Changes, and Calculate Field.

Pipelines results grid

Similar to widgets, you can expand and contract the results grid to a different size that persists across all sessions.

To minimize the results grid, click the down-facing arrow (similar to widgets).
