Display row number in WinForms DataGridView

In WinForms Applications, to display the row number in the row header, we could use the RowPostPaint event of DataGridView control.


USAGE:
Suppose grid is named as dgvUserDetails

DELEGATE:

this.dgvUserDetails.RowPostPaint += new System.Windows.Forms.DataGridViewRowPostPaintEventHandler(this.dgvUserDetails_RowPostPaint);

CODE:
private void dgvUserDetails_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
{
        using (SolidBrush b = new SolidBrush(dgvUserDetails.RowHeadersDefaultCellStyle.ForeColor))
        {
              e.Graphics.DrawString((e.RowIndex + 1).ToString(), e.InheritedRowStyle.Font, b, e.RowBounds.Location.X + 10, e.RowBounds.Location.Y + 4);
        }
}


Don’t try to manipulate the Code part much because the X and Y are calculated co-ordinates in the row header area or you can customizse test it yourself to see the various results.
