Notes

  • In the confirmation dialog there are two buttons. The confirm button is in the primary position and the cancel button is in the secondary position.
  • If Confirmation Header and Confirmation Message are both null, the interface refreshes and the Save Value To state change occurs once the user clicks the button. If either is not null, the confirmation dialog box displays. The interface only refreshes and the Save Value To state change only occurs if the user clicks the confirm button.
  • When Style is "DESTRUCTIVE" and a confirmation dialog box is enabled, the confirm button displays in "DESTRUCTIVE" and the cancel button displays in grey. All other Style options result in a "PRIMARY" confirm button and a "SECONDARY" cancel button.
