Populating RSS XML Feed or XML data on Datagrid
Posted By Sarin on Jan 24, 2013     RSS Feeds     Latest Hinduism news

Data is the backbone of any business application and one of the major issues in silver light is interacting with data source to retrieve data. For small line of business application, quite often the data is stored in xml. So, in this article, we will see how to retrieve data from xml data source and display it on silverlight data controls like datagrid. Additionally I will also show how to bind xml rss feed on silver light datagrid.
Populating Xml data on datagrid
In this example, my xml file will be in the client bin folder of web project. I have kept my xml small with the following data  
  <News  Title="Russia checking 'dangerous' plane incident above Kabul"  Url=""/>
  <News  Title="Amanat' scored high in last exam, was friendly and popular: college"  Url=""/>
  <News  Title="Reliance Communications net profit falls 44%, shares plunge 9%"  Url=""/>
  <News  Title="Investors expect too much from India: Kamal Nath"  Url=""/>

Above xml file contains some of the news title and url from I will populate this news item on click of a silver light button.  My Xaml and code behind will look like
<Button Margin="220,20,0,0" HorizontalAlignment="Left" Grid.Row="1" Width="100" Height="30" Content="Read News Feed" Click="btnNews_Click"/>
<sdk:DataGrid Width="1200" x:Name="dgNews" Grid.Row="0" VerticalAlignment="Top" Height="200" HorizontalAlignment="Left" AutoGenerateColumns="True" />

Code behind
  private void btn_Click(object sender, RoutedEventArgs e)
            WebClient webclient = new WebClient();
          webclient.DownloadStringCompleted += new DownloadStringCompletedEventHandler(btn_DownloadStringCompleted);
            Uri Path = new Uri("News.xml", UriKind.Relative);
  void btn_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
            if (e.Error == null)
                XDocument doc = XDocument.Parse(e.Result);
                IEnumerable<News> list = from n in doc.Descendants("News")
                                         select new News
                                               Title = (string)n.Attribute("Title"),
                                               Url = (string)n.Attribute("Url")
                dgNews.ItemsSource = list;
   public class News
            public string Title  get; set;
            public string Url  get; set;
In the above code, I have defined a news class with two properties. Then, I have used this class to populate the news item on click a button. On button click, I have instantiated a web client to download the data in the xml file and then this string data is parsed to retrieve news items.  If the downloading of data encounters some error then the relevant error message is shown else the datagrid is populated with the news item. I have used the xml Ling query to parse the xml data. My populated datagrid will look like

Populating XML News Feed
Next we will populate the news feed of Url for news feed Is
I will just replace the local xml file path in the above code with this URL and the remaining code behind is  
void newsClient_DownloadStringCompleted(object sender,DownloadStringCompletedEventArgs e)
            if (e.Error == null)
                XmlReader reader = XmlReader.Create(new StringReader(e.Result));
                SyndicationFeed newsFeed = SyndicationFeed.Load(reader);
                IEnumerable<NewsFeed> newsList = from news in newsFeed.Items
                         select new NewsFeed
                           Title = news.Title.Text,
                           Summary = news.Summary.Text,
                           Url = news.Links.FirstOrDefault().Uri.ToString(),
                           PublishedDate = news.PublishDate.Date,
                dgNews.ItemsSource = newsList;
                MessageBox.Show("Error: " + e.Error);
        public class NewsFeed
            public DateTime PublishedDate  get; set;
            public string Title  get; set;
            public string Url  get; set;
            public string Summary  get; set;

You need to add the System.ServiceModel.Syndication namespace to use the above code. In this piece of code, I have defined a NewsFeed class with four properties to store the news data retrieved from news feed.
On click of the button, I have used the xml reader class along with syndicationfeed class to parse the xml feed. In this syndicationfeed, I will get all the properties associated with the news item. These properties are populated onto the datagrid using NewsFeed Data class.
My populated datagrid look like:

Attached is the sample source code.
In this article, we will see how to download xml data, parse xml contents and bind it to silverlight datagrid.
