Esempio

Nell'esempio di codice seguente viene illustrato l'uso di questo membro.

        e.ColumnIndex && e.RowIndex >= 0)

            e.CellBounds.Y + 1, e.CellBounds.Width - 4,
            e.CellBounds.Height - 4);

        using (

                // Erase the cell.
                e.Graphics.FillRectangle(backColorBrush, e.CellBounds);

                // DataGridView takes care of the others).
