如果是Oracle，可以Select rownum，...
否则，你可以用一个For循环，为DataSet中的每一行计算出一个递增的数字。

private void dataGrid1_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
{

int row =1;
int y = 0;
if(this.currentDataSet != null)
{
int count =this.currentDataSet.Tables[0].Rows.Count;

while( row <= count)
{
//get & draw the header text...

string text = string.Format(" {0}", row);

y = this.dataGrid1.GetCellBounds(row - 1, 0).Y + 2;

e.Graphics.DrawString(text,this.dataGrid1.Font, new SolidBrush(Color.Black),2,y);

row ++;
}
}

}
