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>&nbsp;
                                <asp:Label runat="server" ID="TopServerTime"></asp:Label>
                            </div>
                        </ContentTemplate>
                    </SC:DynamicPanel>
