Need help with DataList control

[costintrifan]

Hello, everybody!

I have a DataList control which displays data from 3 different xml files as DataSource.
To select which DataSource to display in the DataList I use a ComboBox.

The code for DataList is this:

<asp:DataList ID="DataRepeater" runat="server" HorizontalAlign="Left">
	<HeaderTemplate>
      	<table id="RssDataTable" cellpadding="0" cellspacing="0">
            	<tbody>
	</HeaderTemplate>
      <ItemTemplate>
           	<tr>
                 	<td class="DataRowTemplate">
                       	<asp:HyperLink ID="DataLink" runat="server"
							NavigateUrl='<%#Container.DataItem("Url")%>'
							ToolTip='<%#Container.DataItem("Name")%>'
							Target="_tabFrame"
							Text='<%#Container.DataItem("Name")%>'>
				</asp:HyperLink>
			</td>
		</tr>
	</ItemTemplate>
	<SeparatorTemplate>
      	<tr>
            	<td style="height: 2px;"></td>
		</tr>
	</SeparatorTemplate>
      <FooterTemplate>
      	</tbody>
		</table>
	</FooterTemplate>
</asp:DataList>

To navigate through records I use an Iframe as target for my DataList records (which are displayed as HyperLinks).
The Iframe is inside a TabPanel (the control from Ajax Toolkit) and it looks like this:

	<cc1:TabContainer ID="TabManager" runat="server" ActiveTabIndex="0">
      	<cc1:TabPanel ID="TabPanel1" runat="server" TabIndex="0">
            	<HeaderTemplate>
                  	<asp:Label ID="TabCaptionLabel" runat="server">Tab Caption</asp:Label>
			</HeaderTemplate>
                  <ContentTemplate>
                  	<iframe id="_tabFrame" name="_tabFrame"
					runat="server" allowtransparency="true" enableviewstate="true"
                              frameborder="0" marginheight="0" marginwidth="0" scrolling="auto" class="TabFrame">
				</iframe>
			</ContentTemplate>
		</cc1:TabPanel>
	</cc1:TabContainer>

Every time I click on a record in DataList the Iframe displays the related page of the record (using NavigateUrl='<%#Container.DataItem("Url")%>')

To close the active TabPanel from the TabManager I would use this:

	<asp:HyperLink ID="CloseTabHyperLink" runat="server">Close tab</asp:HyperLink>

So, this is what I have.

But this is what I want to do:
- each time I click on a record I want to add a new TabPanel + an Iframe to display the page, inside my TabManager
- the caption of the tab I create should have the same data as the record has ( '<%#Container.DataItem("Name")%>' )

The problem is that whenever I select a record from the DataList the page is displayed in the Iframe whithout posting back the page.
So I need to know how can I create a new TabPanel inside a TabManager. (Notice that I've tried to create a few but all I could do was to add just one; when I wanted to add more than one, I got an exception : "The index was out of range".

I would appreciate any help! Thank you!
