GridView通過RowDataBound事件獲取字段值、數據源列值

如果數據源有某一列，而在綁定到GridView時不顯示該列，編程時要用到該列的值可以用以下方法：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            DataRowView dr = (DataRowView)e.Row.DataItem;
            if (dr["btype"].ToString() == "1")
                e.Row.ForeColor = System.Drawing.Color.Red;
        }
    }
