Grid / Transactional updates
Targeted add / update / remove of rows by their stable identifier (rowKey via getRowId) without recreating the whole data array. The grid patches the State Store directly and only invalidates the virtualizer cache for the affected rows.
Transactional updates
Click Add row, Update middle row, or Remove last row to apply a transaction. Each action calls
grid.applyTransaction and the grid updates only the affected rows instead of rebuilding the dataset.Rows: 0
Uses grid.applyTransaction({ add, update, remove }) to patch rows by their stable getRowId without recreating the whole data array.
