Answer 1

In the XAML part i did the following

<RichTextBox  Name="PresenterDescription"  VerticalAlignment="Top" FontSize="16">
            <Paragraph >
                       <Hyperlink Click="readMoreclick">
                            <Underline Foreground="White">read more..</Underline>
                      </Hyperlink>
             </Paragraph>
 </RichTextBox>

And in c# part the text to be displayed before the link as..

PresenterDescription.Selection.Text = "Text to be displayed";

And finally the event handler for link click..

  private void readMoreclick(object sender, RoutedEventArgs e)
         {
            WebBrowserTask webBrowserTask = new WebBrowserTask();
            webBrowserTask.Uri = new Uri("www.example.com", UriKind.Absolute);
            webBrowserTask.Show();
         }
