RadEditor uses two different free libraries to provide Import to RTF
and Export to RTF
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.
underline - supported
foreground and background colors - supported
table elements - unsupported
indentations - unsupported
HTML to RTF (export)
underline - unsupported
foreground and background colors - unsupported
table elements - partially supported
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.
