Controls array is empty in template?
posted

I have a WebExplorerBar I am attempting to use as a replacement for WebPanel.  I'm adding a control template and trying to bind to a ul list.  I have javascript that will "scroll" through the UL showing one item at a time.  The problem is, when i try to access the ListView item in the template, FindControl is returning null.  If i look at the ControlCollection object in the template, (either via FindTemplateByID or Templates[0] of the explorer) it comes back with 0 items.  What am i doing wrong?

 

    <ig:WebExplorerBar runat="server" ID="NewsExplorer" Width="100%">

        <Groups>

            <ig:ExplorerBarGroup Text="News and Headlines">

                <Items>

                    <ig:ExplorerBarItem TemplateId="NewsItem">

                    </ig:ExplorerBarItem>

                </Items>

            </ig:ExplorerBarGroup>

        </Groups>

        <Templates>

            <ig:ItemTemplate TemplateID="NewsItem">

                <Template>

                    <asp:ListView ID="HeadlineFader" runat="server" EnableViewState="false">

                        <LayoutTemplate>

                            <ul id="newsfade">

                                <asp:PlaceHolder ID="itemPlaceholder" runat="server" />

                            </ul>

                        </LayoutTemplate>

                        <ItemTemplate>

                            <li class="newsitems">

                                <asp:HyperLink ID="NewsLink" runat="server" NavigateUrl="#" rel='<%# "#NEWS" + Eval("ID") %>' title='<%#Eval("TEXT") %>' Text='<%# Eval("TITLE")%>' />

                            </li>

                        </ItemTemplate>

                    </asp:ListView>

                </Template>

            </ig:ItemTemplate>

        </Templates>

    </ig:WebExplorerBar>

 

(CodeBehind)

        ItemTemplate temp = this.NewsExplorer.FindTemplateById("NewsItem");

        ListView HeadlineFader = temp.FindControl("HeadlineFader") as ListView;

        HeadlineFader.DataSource = NewsData.GetNews();

        HeadlineFader.DataBind();
