allowSelectAll

Specifies whether a user can select all rows at once.

Type:

Boolean

Default Value: true

If this option is set to true, it allows a user to select all rows at once by pressing Ctrl + A or clicking the check box in the selection column's header. The "Select All" check box also allows a user to deselect all rows. The select all functionality allows selecting/deselecting only those rows that meet filtering conditions if a filter is applied.

If this option is set to false, it disables the select all functionality. In this case, the check box clears selection and is hidden if no rows are selected.
