如何对GridView行自动编号？

时间：2010-11-03 来源：与时俱进

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        Label olabel;
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            olabel = (Label)e.Row.Cells[0].FindControl("lblNo");
            olabel.Text = Convert.ToString(e.Row.RowIndex + 1);
        }
    }
如果遇到有分页时，以上代码对每一页都是从1开始编号，所以对于有分页的情况需要修改成：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        Label olabel;
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            olabel = (Label)e.Row.Cells[0].FindControl("lblNo");
            olabel.Text = Convert.ToString(GridView1.PageIndex * GridView1.PageSize + e.Row.RowIndex + 1);
        }
    }
