    Hi all I know there is NewsRotator Sample.
    Unfortunately, in this example, the NewsRotator require a image to work. I am trying to make a NewsRotator + NewsTicker without having to create/upload a image for each news_items link.

    When I accessing the DB (sf_news_items) in an attempt to get the URL link to each news_items, I find that I can only get a UrlName which is not sufficient to get to the correct news_items from my NewsRotator. To make matter worse, I manually edited the published date for some of the news_items and cannot trace how sitefinity maintain the links to each news_items without using image.

    attached is mine ascx files which i using for my NewsRotator. Is creating a image a must for linking of news_items?
    Result of my NavigateUrl: <mysite>/<projectname>/<ascx folder>/<UrlName>
    Correct NavigateUrl: <mysite>/<projectname>/<news_items path>/<year>/<month>/<date>/<UrlName>

    <%@ Control Language="C#" AutoEventWireup="true" CodeFile="NewsTicker.ascx.cs" Inherits="NewsTicker" %>
    <div class="container">
        <div id="news_announcements" class="news_announcements">
            <div id="news_announcements_left"><strong>News & Announcements</strong></div>
            <div id="news_announcements_right">
                <telerik:RadRotator ID="RadRotator1" runat="server" height="26px" width="550px" ItemHeight="26px" ItemWidth="550px" RotateType="SlideShowButtons" ScrollDuration="1" FrameDuration="7000"
                    <ControlButtons LeftButtonID="homenews1_btn_news_Prev" RightButtonID="homenews1_btn_news_Next" />
                        <asp:HyperLink runat="server" ID="newsLink" NavigateUrl='<%# DataBinder.Eval(Container.DataItem, "UrlName") %>'>
                            <telerik:RadTicker ID="Radticker1" runat="server"
                                    <telerik:RadTickerItem Text='<%# Eval("Title").ToString().Substring(0,Math.Min(80,Eval("Title").ToString().Length)) + " ... (" + Eval("PublicationDate", "{0:dd MMM yyyy}") + ")"%>' />
            <div id="news_announcements_view"><a href="../newsroom" id="news_announcements_view">View All News</a></div>

    Hello Jingyuan,

    In the code behind you need to add additional logic because this link must point to a page that hosts a NewsView control, you should manually make query and get this page. In the following example the TargetNewsPage is represented by a read-only property:
    private PageNode targetNewsPage;
    protected PageNode TargetNewsPage
            if (this.targetNewsPage == null)
                this.targetNewsPage = App.WorkWith().Pages()
                            .Where(p => p.Page != null &&
                                        p.Page.Controls.Where(c => c.ObjectType.StartsWith(typeof(NewsView).FullName)).Count() > 0)
            } //it can still be null in case there is no page with a NewsView on it
            return this.targetNewsPage;

    Refer to the complete example here.

    Best wishes,
