Esempio

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

private void dataGridView1_CellPainting(object sender,
System.Windows.Forms.DataGridViewCellPaintingEventArgs e)

    if (this.dataGridView1.Columns["ContactName"].Index ==
        e.ColumnIndex && e.RowIndex >= 0)

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

        using (
            Brush gridBrush = new SolidBrush(this.dataGridView1.GridColor),
            backColorBrush = new SolidBrush(e.CellStyle.BackColor))
        {
            using (Pen gridLinePen = new Pen(gridBrush))
            {
                // Erase the cell.
                e.Graphics.FillRectangle(backColorBrush, e.CellBounds);

                // Draw the grid lines (only the right and bottom lines;
                // DataGridView takes care of the others).

                // Draw the inset highlight box.
                e.Graphics.DrawRectangle(Pens.Blue, newRect);
