WinForms Data Grid - How to use an unbound checkbox column to select data rows

The Grid View in the Data Grid control can display a built-in checkbox column. Users can use the checkbox column to select multiple rows.

Do the following to enable the checkbox column:

• Enable the View.OptionsSelection.MultiSelect option.
• Set the View.OptionsSelection.MultiSelectMode property to CheckBoxRowSelect.

In v18.1+, you can sync row selected states with a Boolean field in the bound data source. A checkbox column's bound mode ensures that row selection persists whenever you filter or group grid data.
