前台的代码
        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="true" 
            Font-Size="12px" Width="768px" onrowdatabound="GridView1_RowDataBound" onrowdeleting="GridView1_RowDeleting" 
            onrowcancelingedit="GridView1_RowCancelingEdit" onrowediting="GridView1_RowEditing" 
            onrowupdating="GridView1_RowUpdating" >
            <columns>
                <asp:TemplateField HeaderText="选择">
                <ItemTemplate>
                    <asp:CheckBox ID="CheckBox1" runat="server" />
                </ItemTemplate>
                </asp:TemplateField>
                <%--
                <asp:BoundField DataField="id" HeaderText="ＩＤ" />
                <asp:BoundField DataField="dtime" HeaderText="时间" />
                <asp:BoundField DataField="value1" HeaderText="参数一" />
                <asp:BoundField DataField="value2" HeaderText="参数二" />
                
                <asp:CommandField HeaderText="删除" ShowDeleteButton="True" ControlStyle-Width="50px"  />
                <asp:CommandField HeaderText="编辑" ShowEditButton="True"  ControlStyle-Width="50px"  />
                
                 --%>
            </columns>
            
            <PagerSettings Visible="False" />
        </asp:GridView>
我想在后台中生成，以下是我创建一列的方法
            BoundField BFPlaceID = new BoundField();
            BFPlaceID.DataField = "PlaceID";
            BFPlaceID.HeaderText = "站点";
            GridView1.Columns.Add(BFPlaceID);
我想在一列中设置选择列时就不知道怎么弄了，我看了下前台的写了如下代码，出错了，要如何设置呢？
        TemplateField TFCheck = new TemplateField();
        TFCheck.HeaderText = "选择";
        CheckBox CBTF = new CheckBox();
        CBTF.ID = "CheckBox1";
        TFCheck.ItemTemplate = CBTF;
        
        GridView1.Columns.Add(TFCheck);
