Free control - Hybrid LinkLabel and HtmlTextBlock for Silverlight 3

I need a simple HTML renderer ( like HtmlTexBlock ) which also allows to intercept click on custom defined link ( like LinkLabel ) looking like hyperlink. Does anything like that exist as free software ?

From stackoverflow

• I don't know of any but if you only want one link in your html text could you maybe template a button using the htmltextblock as the content and capture the click event and navigate to desired page. I know it will not work if you have multiple links in your html text however it is unclear what your exact requirment is.

  eg.

  <Button x:Name="btnhtml" Width="63" >
           <htmltextblock Text="Hello World"></htmltextblock>
  </Button>
