How can I disable the Complete Message Box from the SpellCheck in the RadRichTextEditor?

In RadSpellChecker I can use the property EnableCompleteMessageBox, but in RadRichTextEditor I can't find it.

 

Regards.

Hello, Omar,   

In the latest version of Telerik UI for WinForms suite RadRichTextEditor doesn't use internally RadSpellChecker. It has its own spell-checking functionality: https://docs.telerik.com/devtools/winforms/richtexteditor/features/spellcheck

The default implementation of the SpellCheckingDialog doesn't allow customizing the dialog in such a way to skip showing the alert for spell-checking completion. However, you can build your own spell-checking dialog which inherits RadForm and implements the ISpellCheckingDialog interface. Thus, you can achieve any custom behavior that you need in the dialog.

I hope this information helps. If you have any additional questions, please let me know. 

Regards,
Dess
