在线等！！！求一段关于获取DataGrid某行某列值的代码

Question

如题，求一段Page Language="VB"的示例代码
大致情况如下：关于DataGrid的批量修改，根据一组查询条件从数据库中读取一批记录与DataGrid绑定，修改后，再重新写回数据库，目前数据的读取和修改已实现，先求如何将一修改后的数据写回数据库。
我想写回数据库首先就要把DataGrid中的数据逐行逐列读取出来，再用update写回去，不知道是不是这样，还是大家有更好的办法？
前台代码：
<div runat="server" id="main" visible="false" style="width:781px;height:303px; overflow:auto">
                                            <ASP:DataGrid id="DataGrid1" runat="server" Width="100%" BackColor="white" BorderColor="black" CellPadding="3" CellSpacing="0" Font-Size="9pt" AutoGenerateColumns="False" HeaderStyle-BackColor="darkred" HeaderStyle-ForeColor="white">
