Search/Replace/Spell check across multiple RichTextBoxes

[Bob]

I have multiple RichTextBoxes (5) in my application and I need to support Search/Replace across all RichTextBoxes.  Also, I have similar requirements for Spell Check/Find Next Error.  How do I go about implementing these functionality?

Hello Bob,

The default UI that RadRichTextBox uses is designed to work with one instance of RadRichTextBox and the customization options provided (implementing a custom dialog and adding it through MEF) also work this way.
You can download the source of the controls and see how the FindReplaceDialog has been implemented and try to implement a similar dialog, which will continue searching the text in the next RadRichTextBox when the end of the current document has been reached. The same approach could be adopted with the SpellCheckingDialog.
