By default, multiple selection is performed using the ctrl or shift key. You can also perform multiple selection by using Checkboxes that are bound to the Grid rows or using the checkbox bound to the header.
The Checkbox can be bound to the Grid rows using the template property of the Grid and to the Grid header using the headerTemplateID property of the Grid. The template property is used to bind unbound column to the Grid. The headerTemplateID is used to add template within the header element.
The following example explains in detail on how to perform multiple selection of records using Checkboxes.
The following screenshot displays the result.
