I'm using the RadRichTextBox to replace the C# default rich text box.  My hope was to be able to enable spell checking so that users would see the red wavy lines under misspelled words.  However, when I set IsSpellCheckingEnabled to true, performance is unacceptable.  With only a few pages of text, even scrolling the control is slow and jerky.  Disabling spell check allows smooth scrolling, but defeats the purpose.

Is there anything I can do to fix this?  Will performance be addressed in a later release?

Hi Jason,

Thank you for writing.

I can confirm this behavior. I have logged it in our Feedback Portal. You can track the item for status changes and add your vote for it here.

Unfortunately there is no way to speed up the spell checking at this point. 

I hope this is not a show stopper for you.

Thanks Dimitar.  For the moment we have set IsSpellCheckingEnabled to false, and provided interactive spell check to the users with the RadSpellChecker.  It's not ideal, but not a show stopper.
