    Dear Support,
    I'm trying to develop a DocumentManagementSystem. For the time being, we are using Infragistics together with the TxTextControl.
    But I found that both are not supporting WPF and MVVM very well, so I asked again for a new evaluation of Telerik and other Thirdpary-controls.

    During comparison of the RichTextEditor I found out, that unfortunately (!) your RTF-Box does need significantly more time to load RTF or DOCX-Files than other Controls. Also scrolling ist not very smooth. It doesn't matter if the document has just 1-2 pages or over 10.
    So I furthermore compared with your WinForms-Version and found out that the WinForms-RichTextBox is as fast as I would expect.

    Referring to this thread : Rich Text Box Performance Issue
    might there be a bug which increases loadingtime of documents as well?

    I would be very grateful if you could crosscheck with the RTF-Box of Q3 2012. Even better would be, if you could give me a link, where to download the older version in order to check this by myself.

    Thank you very much in advance. Telerik would be my first choice, but it really depends on the speed and smootheness of the RTFBox.

    PS: Any news about supporting DOC instead of DOCX only? Or do we still have to convert the documents, as you are already mentionening in the older threads?

    Hi John,

    I am not sure what is the version you are currently evaluating, however we generally advise to use our latest and greatest release in order to see whether RadRichTextBox for WPF fits your needs.

    In case you are currently testing the Q1 2013 SP1 version of the control, note that there is a known issue in regard of performance related to documents containing tables. The problem has been resolved and will no longer be present in the upcoming in a couple of days Q2 2013 version.

    Additionally, we are currently working on some major performance optimizations which will reduce both the loading and the scrolling (inserting, deleting, etc.) time of documents. Unfortunately, I am unable to commit to a certain time-frame when these changes might be released. As of now, the only performance hints we have are listed in this help article.

    I hope this is helpful! Let us know if you have any other comments or questions.
