Such functionality should be possible to achieve with RadRichTextBox and HtmlFormatProvider
However, please note that the RadRichTextBox control is closer to a word processor than an HTML editor, so the HTML support has its limitations. I suggest you refer to these articles for more detailed information: HTML Support
, Import/Export settings
When it comes to what approach to adopt, you can try using HtmlDataProvider
in order to create a two-way
binding between a RadRichTextBox control and a TextBox (for example) similar to this online example
I hope this helps!
