如何获取DataList内GridView某行的数据

DataList嵌套了GridView，DataList的每一个Ietm里，都有一个GridView，我在DataList的ItemDataBound事件里写代码，需要做条件判断 protected void dltA1_ItemDataBound(object sender, DataListItemEventArgs e)    {        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)        {            DataTable dt2 = new DataTable();            dt2 = adoDB.DS.Tables[0].Clone();            GridView gvList1 = (GridView)e.Item.FindControl("gdvA2");            foreach (DataRow row in adoDB.DS.Tables[0].Rows)            {                if ((Int32)row[5] == 3 )                {                    dt2.Rows.Add(row.ItemArray);                }            }            if (e.Item.ItemType == ListItemType.Item)            {                gvList1.DataSource = dt2.DefaultView;                gvList1.DataBind();            }        }    } 在判断row[5] == 3的同时，还需要判断row[6]是不是小于该Item内GridView第一列绑定的数据，请问我如何获取到这个数据并做判断呢？

最简单的就是使用模板列
参照：<asp:GridView ID="GridView1" Width="100%" runat="server" HorizontalAlign="Center" CellPadding="2" AutoGenerateColumns="False" DataKeyNames="InfoCode" PageSize="4" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing" OnRowDataBound="GridView1_RowDataBound">
<RowStyle CssClass="DataListBK1" />
<AlternatingRowStyle CssClass="DataListBK2" />
<HeaderStyle CssClass="DataListTitle" />
<Columns>
<asp:TemplateField HeaderText="选择" >
<ItemTemplate>
<asp:CheckBox ID="chkChecked" runat="server" />
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" Wrap="false"/>
<HeaderStyle Width="40px" Wrap="false" />
</asp:TemplateField>
