GridView专栏

鉴于GridView的强大，鄙人突然心血来潮，想把GridView单独拿出来整理一下。

（一）gridview如何加自增长列

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[0].Text = indexID.ToString();
        }
    }
