又有一个Repeater的例子

                                            <asp:repeater id="rptRoleMain" runat="server">
                                                <itemtemplate>
                                                    <b>
                                                        <asp:CheckBox ID="MainCbb" Checked='<%# GetCbbValue(DataBinder.Eval(Container.DataItem,"MenuID")) %>' Runat=server Text='<%# DataBinder.Eval(Container.DataItem,"MenuName")%>'>
                                                        </asp:CheckBox>
                                                    </b>
                                                    <br>
                                                    <!-- 子Repeater开始 -->
                                                    <asp:repeater id="childRepeater" runat="server" datasource='<%# ((DataRowView)Container.DataItem).Row.GetChildRows("myrelation") %>'>
                                                        <itemtemplate>
                                                        <asp:CheckBox ID="DetailCbb" Checked='<%# GetCbbValue(DataBinder.Eval(Container.DataItem,"MenuID")) %>' Runat=server Text='<%# DataBinder.Eval(Container.DataItem,"MenuName")%>'>
                                                            </asp:CheckBox>
                                                        </itemtemplate>
                                                    </asp:repeater>
                                                    <!-- 子Repeater结束 -->
                                                </itemtemplate>
                                            </asp:repeater>
                                            <!-- 父Repeater结束 -->

不成功，

但如下成功

 1                                        <!-- 父Repeater开始 -->
 2                                            <asp:repeater id="rptRoleMain" runat="server">
 3                                                <itemtemplate>
 4                                                    <b>
 5                                                        <asp:CheckBox ID="MainCbb" Checked='<%# GetCbbValue(DataBinder.Eval(Container.DataItem,"MenuID")) %>' Runat=server Text='<%# DataBinder.Eval(Container.DataItem,"MenuName")%>'>
 6                                                        </asp:CheckBox>
 7                                                    </b>
 8                                                    <br>
 9                                                    <!-- 子Repeater开始 -->
10                                                    <asp:repeater id="childRepeater" runat="server" datasource='<%# ((DataRowView)Container.DataItem).Row.GetChildRows("myrelation") %>'>
11                                                        <itemtemplate>
12                                                        <asp:CheckBox ID="DetailCbb" Checked='<%# GetCbbValue(((DataRow)Container.DataItem)["MenuID"]) %>' Runat=server Text='<%# ((DataRow)Container.DataItem)["MenuName"]%>'>
13                                                            </asp:CheckBox>                                                            
14                                                        </itemtemplate>
15                                                    </asp:repeater>
16                                                    <!-- 子Repeater结束 -->
17                                                </itemtemplate>
18                                            </asp:repeater>
19                                            <!-- 父Repeater结束 -->
