PlaceHolder 容器占位,不输入当容器代码,并让其换行.

前台:

 

<asp:PlaceHolder ID="PHD_"  runat="server"></asp:PlaceHolder>

<asp:Repeater ID="rptTest" runat="server">
                                <HeaderTemplate>
                                    <table style="width: 100%">
                                </HeaderTemplate>
                                <ItemTemplate>
                                    <asp:PlaceHolder ID="PlaceHolder1" runat="server" Visible='<%# (Container.ItemIndex + 1) % 7 ==1 %>'><%--出现7列时换行--%>
                                        <tr>
                                    </asp:PlaceHolder>
                                    <td style="width: 14%; text-align: center">
                                        <asp:HyperLink ID="linkUsername" runat="server"><%#Container.DataItem %></asp:HyperLink>//输出值
                                    </td>
                                    <asp:PlaceHolder ID="PlaceHolder2" runat="server" Visible='<%# (Container.ItemIndex + 1) % 7==0 %>'>
                                        </tr> </asp:PlaceHolder>
                                </ItemTemplate>
                                <FooterTemplate>
                                    </table>
                                </FooterTemplate>
                            </asp:Repeater>
