Performance
Virtualization and infinite scroll for large datasets.
Performance features keep large grids fast by rendering only what's visible. Row
virtualization (enableVirtualization) is the big lever; enableColumnVirtualization adds
horizontal windowing for very wide grids. Both default off — turn them on for thousands of rows or
hundreds of columns. Virtualization yields to master-detail, grouping, spanning and row pinning,
which need the full DOM.
| Feature | Flag | Default |
|---|---|---|
| Column virtualization | enableColumnVirtualization | false |
| Row virtualization | enableVirtualization | false |
