Answer 1

repeater是否绑定数据，检查页面源码

Answer 2

这个不关panel的事，页面跳转时数据忘了绑了吧

Answer 3

我已经把repeater visible=false掉了，怎么那个<FooterTemplate>
                                                </table>
                                                <hr size="3px" width="90%" />
                                                <asp:Label ID="Label_Empty" runat="server" Text="没有任何搜索结果:-)" Visible='<%# bool.Parse((Repeater_EachType.Items.Count==0).ToString()) %>'
                                                    CssClass="searchempty"></asp:Label>
                                            </FooterTemplate>
这里怎么还会显示没有任何搜索结果:-)" ？？？？

Answer 4

后台代码贴出来。/。。
是不是ispostback问题

Answer 6

我知道哪里出问题了，<FooterTemplate>
                                                </table>
                                                <hr size="3px" width="90%" />
                                                <asp:Label ID="Label_Empty2" runat="server" Text="没有任何搜索结果:-)" Visible='<%# bool.Parse((Repeater_SearchCom.Items.Count==0).ToString()) %>'
                                                    CssClass="searchempty"></asp:Label>
                                            </FooterTemplate>
和
Repeater ID="Repeater_SearchCom" 
没有对上号，因为我有两个repeater因为差不多就直接复制，有些东西没改好，就这样了
