Description

To enable the checkbox selection functionality you should define a select column as shown below:

.Columns(columns => { columns.Select(); })

This column allows you to select grid rows automatically after changing the status of the checkbox to checked. A checkbox is also displayed in the column header to toggle the checked/selected state of all rows in the current page.

Additionally in the demo you can see how to persist selected items across pages. This is achieved by using the PersistSelection(true) method.
