    We need the RTF conversion capability for our Telerik products.  However, there is definitely some problems with handilng multiple font styles within the same document.  To reproduce, use the link to your demo, http://demos.telerik.com/aspnet-ajax/editor/examples/rtfexport/defaultcs.aspx

    Highlight the middle paragraph, then change the font to something other than Times New Roman (like MS Sans Serif).  When you select the 'Export RadEditor content to RTF' button, the resulting file still shows Times New Roman for all paragraphs.  Thinking it was not using the data in the control, I even added some custom text.  The new text showed in the output file, but the font still went back to Times New Roman.

    Any ideas on this?

    Hello Thomas,

    RadEditor uses two different free libraries to provide Import to RTF and Export to RTF features.

    The first one used to provide RFT to HTML importation is available in this CodeProject's article: http://www.codeproject.com/KB/recipes/RtfConverter.aspx.
    The library used for HTML to RTF exportation is available here http://www.codeproject.com/KB/recipes/RtfConverter.aspx.
    As you can see both libraries are written by different developers and they are not fully compatible with each other.

    For your convenience I prepared a list of know limitations of the Import and Export features of both libraries:

    RFT to HTML (Import)

    bold
    - supported. I was able to export bold formatting from the provided by you Bold.rtf file.
    italic - supported
    underline - supported
    foreground and background colors - supported
    table elements - unsupported
    images- unsupported
    indentations - unsupported


    HTML to RTF (export)


    bold - supported.
    italic - supported
    underline - unsupported
    foreground and background colors - unsupported
    table elements - partially supported - table borders are not exported
    images- unsupported
    indentations - supported
    font family and size - unsupported

    The unsupported scenarios are hard for development and require more time for implementations and testing. Our development is concentrated currently on producing valid XHTML content and the import and export problems are logged with medium priority in our ToDo list. That is why we could not provide firm estimate for when the unsupported features will be available.

    Please note that good RTF import and export tools are very expensive. If you are currently unsatisfied with the offered by RadEditor RTF functionality, you could search in Internet for another free or paid RTF to HTML importation and HTML to RTF exportation tools and we will help you to integrate them with RadEditor.

    Thank you for the reply.  However, the two links regarding the conversion libraries you provided are the same.  If Telerik is going to include this capability, don't you think they would want to ensure it provides a sufficient level of functionality to be considered feature complete.

    Here is the link to the XHTML to RTF export: http://www.codeproject.com/KB/HTML/XHTML2RTF.aspx

    The RTF support is indeed basic but RadEditor is an XHTML editor, but not a PDF or RTF editor and its main goal is to produce and export valid XHTML. That is why the improvement of the RTF support is logged with medium priority in our ToDo list.
