I think you are using ListBox .So try like this

    <ListBox x:Name="lstEmployee" SelectionChanged="lstEmployee_SelectionChanged_1" /> <br/><br/>

    private void lstEmployee_SelectionChanged_1(object sender, SelectionChangedEventArgs e)
    {
        NewsItem selectedItem = (sender as ListBox).SelectedItem;
        if (selectedItem != null)
        {
            // pass news detail as parameter and take it from you nerw page
            NavigationService.Navigate(new Uri(string.Format( "/Path/YourNewPage.xaml?desc=selectedItem.news_detail_description ", UriKind.Relative));
        }
    }

this link will help you to understand how parameters can be passed between pages.

To pass entire NewsItem to another page, one best approach is to use Application.Current

First create an instance of NewsItem in App.xaml.cs page

public NewsItem selectedNewsItem;

then in your SelectionChanged event handler of ListBox,

    NewsItem selectedItem = (sender as ListBox).SelectedItem;
    if (selectedItem != null)
    {
        (Application.Current as App).selectedNewsItem = selectedItem;
        // Navigate to your new page
        NavigationService.Navigate(new Uri("/YourNewPage.xaml", UriKind.Relative));
    }

Finally, in your new page you can access the selectedNewsItem in the same way as above.

    NewsItem selectedNewsItem = (Application.Current as App).selectedNewsItem;
