    Hi Team,

    While Saving Rad Editor Content as a RTF the content Format was changing (ex: Center alignment wast not coming, Underline)

    i was also checked with the Telerik site , there also format was not coming correctly.

    I'm Saving the Rad Editor content as RTF into database. while Retrieving the RTF from Database and loding into Rad Editor on that time i'm getting the content with the Question Mark Symbols and alignment was not coming correctly.

    Please give the solution as soon as possible.

    Hi Harish,

    RadEditor is using third party tools to provide XHTMLtoRTF and RTFtoXHTML conversions which have some restrictions and limitations. We are aware of the reported issues and are working on fixing them. Unfortunately, at present, I am unable to provide a suitable workarounds for these problems.

    Please excuse us for the inconvenience.

    Best wishes,
    the Telerik team

    how is the status on the rendering problems. We also have some issues, where we save the RTF-Text to the database and some other tools are using the RTF-text in their own solutions. What does NOT seem to work is for instance the vertical alignment of the unordered list items (the identations are changing quite unexpectedly and also sub-list-items are a tricky thing where the indentation is changing.

    Our goal: produce the same RTF-text as Wordpad does, can we achive this and if it's possible, how can we do this? Are there any know workarounds (a customer of ours wants to enter his own RTF-text-fragments)

    We have bought the newest version of the tools a few weeks ago (mainly for addressing RTF issues) and now it's a bit frustrating to see the results of the RTF conversion.

    best regards

    Hi David,

    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)

    - 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
    images- unsupported
    indentations - supported

    You can see the following video which demonstrates how the RTF import and export features work:

    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 I could not provide an exact estimate when the issues will be fixed. I have escalated the problems to the attention of our lead developers and they will consider increasing the priority of these bugs to high for the next Q1 2011 release.

    You should also note that good RTF import and export tools are very expensive and if we integrate such tools in RadEditor, the price of the Telerik suite will be increased a lot. That is why if you are currently not satisfied with the offered by RadEditor RTF functionality, you can 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.
