Multiple Row Selection
With the Bootstrap Grid View, you can activate a specific selection mode to allow end-users to select a single row or multiple rows. To switch this mode to another, use the ASPxGridViewBehaviorSettings.AllowSelectSingleRowOnly property. In single row selection mode, check to see that boxes displayed within the command column's cells are automatically replaced with radio buttons.
If the ASPxGridViewBehaviorSettings.AllowSelectByRowClick option is enabled, end-users can change selection by clicking rows in combination with the SHIFT or CTRL key. In multiple row selection mode, clicking a row while holding down the CTRL key toggles the row's selected state. Contiguous rows can be selected by clicking the first and last rows while holding down the SHIFT key. After this, you can further customize the selection by clicking individual rows while holding down the CTRL key.
