ASP.NET 在GridView中自动添加序号列

 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowIndex != -1)
        {
            int indexID = this.GridView1.PageIndex * this.GridView1.PageSize + e.Row.RowIndex + 1;
            e.Row.Cells[1].Text = indexID.ToString();
        }
    }
