How to import a .rtf file to silverlight 4 richtextbox?

I have a .rtf file and want to put it in a richtextbox in silverlight 4. Unfortunately we do not have .rtf property in silverlight 4 richtextbox, we only have .xaml.

So what i did is to create a FlowDocument, than load the .rtf to this FlowDocument, then format it to xaml. then assigned it to richtextbox. But i got a argumentexception.

I used an ugly solution so far, use a FlowDocument to change the format from rtf to xaml. Then remove the attributes not accepted in SL4 richtext box, codes like below. It works but I hate it. I want to know is there a better solution.

        string xaml = String.Empty;         FlowDocument doc = new FlowDocument();         TextRange range = new TextRange(doc.ContentStart, doc.ContentEnd);          using (MemoryStream ms = new MemoryStream())         {             using(StreamWriter sw = new StreamWriter(ms))             {                 sw.Write(from);                 sw.Flush();                 ms.Seek(0, SeekOrigin.Begin);                 range.Load(ms, DataFormats.Rtf);             }         }           using(MemoryStream ms = new MemoryStream())         {             range = new TextRange(doc.ContentStart, doc.ContentEnd);              range.Save(ms, DataFormats.Xaml);             ms.Seek(0, SeekOrigin.Begin);             using (StreamReader sr = new StreamReader(ms))             {                 xaml = sr.ReadToEnd();             }         }          // remove all attribuites in section and remove attribute margin           int start = xaml.IndexOf("<Section");         int stop = xaml.IndexOf(">") + 1;          string section = xaml.Substring(start, stop);          xaml = xaml.Replace(section, "<Section xml:space=\"preserve\" HasTrailingParagraphBreakOnPaste=\"False\" xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\">");         xaml = xaml.Replace("Margin=\"0,0,0,0\"", String.Empty);

I suggest you take a look at the free VectorLight Rich Text Box control instead.

I need to do something similar (haven't done it yet ...)

I came across NRTFTRee, a C# RTF parser, which should port to silverlight. http://www.codeproject.com/KB/string/nrtftree.aspx
