</tr>
</tbody>
</table>
<br />
<table class="tblAll">

<asp:PlaceHolder ID="phItemPlaceHoler" runat="server"></asp:PlaceHolder>
</tbody>
</table>
</LayoutTemplate>
</asp:ListView>
</asp:Panel>
</ContentTemplate>
</asp:TabPanel>
</asp:TabContainer>
Where, I am getting Question from Table "Question", and its answers from another table "Answers". Each Question is linked with a PageNumber.
so, i have to create TabPanels according to PageNumber from Question, Then Bind Question Label with that Question, and fill 2nd ListView with Answers of that Question.
These answers are dynamic controls based on db entries e.g textbox, checkboxlists, radiobutton lists and may vary for every question.
Now what i am doing is copying tabPanel 1 to new TabPanel and adding question and answers according to db values, but when i am creating 2nd TabPanel, it give me error that
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.
What is the best approach to handle this scenerio.
something like SurverMonkey except i am using tabs for new page.
