查找DataGrid中的模板控件

html代码:

 <asp:DataGrid id="DataGrid1" runat="server" AutoGenerateColumns="False" onitemcreated="DataGrid1_ItemCreated" onitemdatabound="DataGrid1_ItemDataBound">
                <Columns>
                    <asp:TemplateColumn>
                        <ItemTemplate>
                            <asp:CheckBox Runat="server" Text='<%#DataBinder.Eval(Container.DataItem,"item")%>' ID="itemCB" AutoPostBack="True">
                            </asp:CheckBox>
                        </ItemTemplate>
                    </asp:TemplateColumn>
                    <asp:TemplateColumn>
                        <ItemTemplate>
                            <asp:CheckBoxList Runat="server" ID="dqdmCBL" RepeatDirection="Horizontal" RepeatColumns="7" AutoPostBack="true"></asp:CheckBoxList>
                        </ItemTemplate>
                    </asp:TemplateColumn>
                </Columns>
            </asp:DataGrid>

要找到以上的两个控件代码:

for (int t = 0; t < DataGrid1.Items.Count; t++)            

{

CheckBoxList cbl = (CheckBoxList)DataGrid1.Items[i].FindControl("dqdmCBL");

CheckBox chk = (CheckBox)DataGrid1.Items[i].FindControl("itemCB");
