Grid multiple selection can be achieved with help of checkbox in each row. To render checkbox in each grid row, you need to define column type as checkbox using columns-type property. Selection can be persisted on all the operations using selectionSettings- persistSelection property. For persisting selection on the Grid, any one of the column should be defined as a primary key using columns-isPrimaryKey property. In this demo, Grid multiple selection has been enabled with selection persistance. You can also delete multiple records, by clicking the toolbar’s Delete button after selecting the checkboxes. More information on the checkbox selection configuration can be found in this documentation section.
