NewsRotator without using image

Posted by Community Admin on 16-Aug-2011 00:00

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>

NewsTicker.ascx

<%@ 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">

OnItemDataBound="RadRotator1_ItemDataBound">

<ControlButtons LeftButtonID="homenews1_btn_news_Prev" RightButtonID="homenews1_btn_news_Next" />

<ItemTemplate>

<asp:HyperLink runat="server" ID="newsLink" NavigateUrl='<%# DataBinder.Eval(Container.DataItem, "UrlName") %>'>

<telerik:RadTickerItem

Text='<%# Eval("Title").ToString().Substring(0,Math.Min(80,Eval("Title").ToString().Length)) + " ... (" + Eval("PublicationDate", "0:dd MMM yyyy") + ")"%>' />

</items>

</telerik:RadTicker>

</asp:HyperLink>

</ItemTemplate>

</sf:RadRotator>

</div>

<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

get

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)

.Get().FirstOrDefault();

//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.
