在DataGridView控件中的 RowPostPaint事件中：（VB.net源码）

Private Sub dgvRealDataCar_RowPostPaint(ByVal sender As System.Object,ByVal e As System.Windows.Forms.DataGridViewRowPostPaintEventArgs) Handles dgvRealDataCar.RowPostPaint

Dim brush As System.Drawing.Brush = New SolidBrush(dgvRealDataCar.RowHeadersDefaultCellStyle.ForeColor)

e.Graphics.DrawString((e.RowIndex + 1).ToString(),dgvRealDataCar.DefaultCellStyle.Font,Brush,e.RowBounds.Location.X + 12,e.RowBounds.Y + 5)

End Sub
