DataGrid取值问题~

Question

前台代码如下：<asp:DataGrid ID="ShowTg" runat="server" Width="750px" AutoGenerateColumns="False"
                                            BorderColor="#E0E0E0" AllowPaging="True" PageSize="15" OnPageIndexChanged="ShowTg_PageIndexChanged">
                                            <Columns>
                                                <asp:BoundColumn HeaderText="id" DataField="id" Visible="False"></asp:BoundColumn>
                                                <asp:BoundColumn HeaderText="投稿时间" DataField="create_time">
                                                    <HeaderStyle HorizontalAlign="Center" />
                                                    <ItemStyle HorizontalAlign="Center" Width="80px" />
                                                </asp:BoundColumn>
                                                <asp:BoundColumn DataField="login_name" HeaderText="用户名">
                                                    <HeaderStyle HorizontalAlign="Center" />
                                                    <ItemStyle HorizontalAlign="Center" Width="120px" />
                                                </asp:BoundColumn>
                                                <asp:BoundColumn HeaderText="投稿内容" DataField="content"></asp:BoundColumn>
                                                <asp:TemplateColumn>
                                                    <HeaderTemplate>
                                                        <asp:CheckBox id="chkHeader" runat="server" AutoPostBack="False" onclick="javascript:SelectAll(this);"></asp:CheckBox>
                                                    </HeaderTemplate>
                                                    <ItemTemplate>
                                                        <asp:CheckBox id="chkItem" runat="server"></asp:CheckBox>
                                                    </ItemTemplate>
                                                    <HeaderStyle HorizontalAlign="Center" />
                                                    <ItemStyle HorizontalAlign="Center" Width="30px" />
                                                </asp:TemplateColumn>
                                            </Columns>
                                            <PagerStyle HorizontalAlign="Center" Mode="NumericPages" />
                                            <AlternatingItemStyle BackColor="ControlLight" />
                                            <ItemStyle Font-Underline="True" Height="25px" />
                                        </asp:DataGrid>
                                          <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
通过页头的CHECKBOX来控制全选后取消步骤
后台：
    protected void Button1_Click(object sender, EventArgs e)
    {
        for (int i = 0; i < this.ShowTg.Items.Count; i++)
        {
            bool blnIfSelect = ((CheckBox)this.ShowTg.Items[i].FindControl("chkItem")).Checked;
        }
    }
这里可以得到DataGrid中checkbox选中和不选中状态~
问题就是 如何得到DataGrid中<asp:BoundColumn HeaderText="id" DataField="id" Visible="False"></asp:BoundColumn>
这一行的值 我要做删除功能~~
