Preview Section

Preview sections are non-editable regions in data rows that allow large memo fields to be displayed across all View columns, thus the preview section’s width is equal to the total column width.




If the Row Auto-Height or Preview Sections feature is enabled, pixel-based vertical row scrolling is not in effect. See GridOptionsBehavior.AllowPixelScrolling to learn more.
