Due to backward compatibility with Kentico CMS versions prior to 5.5, it is also possible to create a dedicated page with an RSS feed. This way of creating RSS feeds is obsolete now, as syndication web parts provide a much more convenient way of creating RSS feeds.


The default installation contains a simple CMSPages\NewsRss.aspx page which shows how to build your own RSS feed. It works with news items, but you can modify the code so that it displays a different type of documents.


The following code example shows the code of the NewsRss.aspx page.


Please note: If you installed the Kentico CMS project as a web application, you need to rename the CodeFile property on the first line to Codebehind for the code example to be functional.


<%@ Page Language="C#" AutoEventWireup="true" CodeFile="RSS.aspx.cs"

  Inherits="RSSNews" %>

<%@ Register Assembly="CMS.Controls" Namespace="CMS.Controls"

  TagPrefix="cc1" %><?xml version="1.0" encoding="utf-8" ?>

<rss version="2.0">


<title>News RSS</title>

  <link><![CDATA[<%=HttpContext.Current.Request.Url.AbsoluteUri.Remove(HttpContext.Current.Request.Url.AbsoluteUri.Length - HttpContext.Current.Request.Url.PathAndQuery.Length) + HttpContext.Current.Request.ApplicationPath%>]]></link>

<description>News RSS Feed</description>

<cc1:cmsrepeater ID="NewsRepeater" runat="server" OrderBy="NewsReleaseDate DESC" ClassNames=""

  TransformationName="" SelectedItemTransformationName=""





As you can see, the page contains only RSS elements with dynamic code. The RSS items are rendered using a CMSRepeater control with appropriate transformation.


The code behind looks like this:




protected void Page_Load(object sender, EventArgs e)


   Response.ContentType = "text/xml";  



This code changes the output content type to XML.


How to create an RSS feed page for a different document type


If you want to display articles instead of news in your RSS feed, you will need to follow these steps:


1.Create a new ASPX page called articles_rss.aspx.


2.Copy and paste all code from the NewsRss.aspx file except for the <%@ Page %> directive.


3.Change the following properties of the CMSRepeater control:


OrderBy: DocumentModifiedWhen DESC

ClassName: cms.article

TransformationName: cms.article.rssitem

SelectedItemTransformationName: cms.article.rssitem

Path: /%

WhereCondition: leave empty


4.Add the same line of code as used in the NewsRss.aspx.cs code behind file (Response.ContentType = "text/xml") to articles_rss.aspx.cs.


5.Create the trasformation cms.article.rssitem like this in Site Manager -> Development -> Document Types -> ... edit Article ... -> Transformations:



    <guid isPermaLink="true"><![CDATA[<%# GetAbsoluteUrl(GetDocumentUrl()) %>]]></guid>

    <title><![CDATA[<%# Eval("ArticleTitle") %>]]></title>

    <description><![CDATA[<%# Eval("ArticleText") %>]]></description>

    <pubDate><%# Convert.ToDateTime(Eval("DocumentModifiedWhen")).ToString("r") %></pubDate>

    <link><![CDATA[<%# GetAbsoluteUrl(GetDocumentUrl()) %>]]></link>    



This code renders the particular items.
