Hi  Joshua,

Thank you for writing.

The RadRichTextEditor does not work like a regular textbox. So its Text property is only inherited and should not be used. To retrieve the text you can use one of the format providers. Detailed information about how this control works is available in the following articles:

• Frequently Asked Questions
• Import/Export 
• Selection 
• Search
  

In addition, the control supports spell checking out of the box: Spellcheck.

Let me know if you have additional questions.
