I add the following code, just as a test, to a master content aspx file that
contains a

SlideShowExtender and a DataList element.

I get the following error :



The Controls collection cannot be modified because the control contains code
blocks (i.e. <% ... %>).



It's such a sweeping restriction that I wonder if I'm doing something wrong
or if there is a way around it.

Is it true that with the TabContainer one can not use any data binding?



Does it apply to things like <%@ Page and <%@ Register




What control's collection is being modified?





<div style="border:solid 3px red">


<cc1:TabContainer ID="TabContainer2" runat="server" ActiveTabIndex="0"
ScrollBars="Auto" Width="211px">

<cc1:TabPanel ID="TabPanelaa" runat="server" HeaderText="TabPanel1">

Click to expand...

I don't see where you have a <% %> block, but perhaps it is because of
the following reason:

Try to put it to the Placeholder Control, hope this helps
