继续问问，用CheckBox批量修改数据，小弟刚学，大哥大姐指导一下！分少别嫌弃

选择    |    编号   |   名称
---------------------------------
选择框      A-1        AAAA
选择框      B-3        BBBB
根据每一行中的checkbox是否被选择,来修改编号和名称里的textbox项!C#2005 + Access格式如上，请问大家怎么弄！

</html>注意：对于SQL Server 数据库，参数名字不加@。另外注意：不同数据库类型和不同的数据源，UpdateCommand="Update [Student] Set Title = @Title,Gender = @Gender,ClassName=@ClassName Where id=@id"写法和SqlDataSource1.UpdateParameters.Add(new Parameter("@Title", TypeCode.String, ((TextBox)gvr.FindControl("txtTitle")).Text)); 的写法会有所区别。循还一次就行嘛！
每一行设置一个 i ，编号     名称，设置成 Textbox 默认
for(i=0;i<;i++)
{
if(CheckBoxi.Checked)
{
TextBox编号i.Enabled = true;
TextBox名称i.Enabled = true;
}
}
TextBox默认Enabled = false；
