Also what is the supplied reference assembly SampleControls.dll? I notice that within the AdvancedCS20.Demo.master page that the following code references a DynamicPanel defined within SampleControls.dll, could you confirm what this control is and whether it is required for the AdvancedCS20 demo to work correctly as per my question above?
<SC:DynamicPanel CssClass="AjaxPanel" runat="server" ID="AjaxPanel" AutoInitiaize="false">
<ContentTemplate>
<div class="MiddlePanel">
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</div>
<br />
<div class="AjaxBottomPanel">
<asp:DropDownList ID="AjaxMode" runat="server" Width="150px" AutoPostBack="True"
OnSelectedIndexChanged="AjaxMode_SelectedIndexChanged">
<asp:ListItem Value="Atlas">Microsoft Ajax</asp:ListItem>
<asp:ListItem Value="Magic">Magic Ajax</asp:ListItem>
<asp:ListItem Value="None">Do not use Ajax</asp:ListItem>
</asp:DropDownList>
<asp:Label ID="LinkWelcome" runat="server"></asp:Label>
<asp:Label runat="server" ID="TopServerTime"></asp:Label>
</div>
</ContentTemplate>
</SC:DynamicPanel>
