我有TabControl（AjaxToolKit）有2个嵌套ListViews。
代码：
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:TabContainer ID="tcQuestions" runat="server" ActiveTabIndex="0" OnDemand="true" AutoPostBack="false" TabStripPlacement="Top" ScrollBars="None" UseVerticalStripPlacement="false">
<asp:TabPanel ID="tpFirst" runat="server" HeaderText="Page 1" Enabled="true" ScrollBars="Auto"
OnDemandMode="Once">
<ContentTemplate>
<asp:Panel ID="pnlNoData" runat="server">
<asp:LinkButton ID="lbQuestionsAdd" Text="Add Question" runat="server" />
</asp:Panel>
<asp:Panel ID="pnlListView" runat="server">
<asp:ListView ID="lsvQuestions" runat="server" ItemPlaceholderID="phItemPlaceHoler">
<EmptyDataTemplate>
<em>NO RECORD WAS FOUND</em>
</EmptyDataTemplate>
<ItemTemplate>
<tr>
<td>
<asp:Label ID="lblQuestionID" Text='<%#Eval("intQuesId") %>' Visible="false" runat="server" />
<asp:Label ID="lblQuestionTitle" Text='<%#Eval("strQuesTitle") %>' runat="server" />
<%--1.Are you doing job?--%>
</td>
</tr>
<%--Inner Listview--%>
<asp:ListView ID="lsvAnswers" runat="server" ItemPlaceholderID="phItemPlaceHolerAnswers">
<LayoutTemplate>
<table runat="server" id="table1">
<tr runat="server" id="phItemPlaceHolerAnswers">
</tr>
</table>
</LayoutTemplate>
<ItemTemplate>
<tr>
<td>
<asp:PlaceHolder ID="plControl" runat="server" />
</td>
</tr>
</ItemTemplate>
<EmptyDataTemplate>
<em>NO RECORD WAS FOUND</em>
</EmptyDataTemplate>
</asp:ListView>
</ItemTemplate>
<LayoutTemplate>
<table class="tblAll">
<tbody>
<tr>
<td style="width: 125px">
<asp:LinkButton ID="lbtnAddQuestions" runat="server">Add Questions</asp:LinkButton>

<td style="width: 316px">

<td style="width: 64px;">
<asp:Label ID="Label1" runat="server" CssClass="lnkbuttonText" Text="Move Page" />
</td>
<td style="width: 20px;">
<img class="imgicons" src="../Layout/images/right.png" />
</td>
<td>
 
</td>
</tr>
</tbody>
</table>
<br />
<table class="tblAll">
<tbody>
<asp:PlaceHolder ID="phItemPlaceHoler" runat="server"></asp:PlaceHolder>

</LayoutTemplate>
</asp:ListView>
</asp:Panel>
</ContentTemplate>
</asp:TabPanel>
</asp:TabContainer>
在哪里，我从表“问题”得到问题，并从另一个表“答案”得到答案。每个问题都与PageNumber相关联。
所以，我必须根据问题中的TabPanels创建PageNumber，然后使用该问题绑定问题标签，并在第2个ListView填写该问题的答案。
这些答案是基于数据库条目的动态控制，例如textbox，checkboxlists，radiobutton lists，并且每个问题可能会有所不同。
现在我正在做的是将tabPanel 1复制到新TabPanel并根据db值添加问题和答案，但是当我创建第二个TabPanel时，它会给我错误
Cannot unregister UpdatePanel with ID 'ContentPlaceHolder1_tcQuestions_tpFirst_updatePanel' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported.
处理此场景的最佳方法是什么？
类似SurverMonkey之类的东西，除了我使用新页面的标签。
