L’exemple de code suivant illustre l’utilisation de ce type. Cet exemple fait partie d’un exemple plus large disponible dans How to : Customize the Appearance of Rows in the Windows Forms DataGridView Control.

    // with the custom selection background.
    if ((e.State & DataGridViewElementStates.Selected) ==
                DataGridViewElementStates.Selected)
