Hello Shawn Weisfeld,
In the 2011 Q2 release we introduced the RadCompositionInitializer class which aims to give more control over the MEF composition that is done under the hood of the RadRichTextBox control. The RadCompositionInitializer class is used to satisfy all the imports in the rich text box. It uses shared CompostionContainer that is available statically through the RadCompositionInitializer.Container property. In scenarios like yours you can replace the default container that is created with you own that is more suited to you needs.
What we don't support at this moment is a way to force recomposition. This means that once the spell-checker loads its dictionaries once, there is no way to force him to check whether there are new dictionaries available in the composition container. Fortunately there are workarounds to this problem. One option is to create a new instance of DocumentSpellCheker class and assign it to the SpellChecker property of the RadRichTextBox. The new instance will automatically discover and use all the dictionaries that are available. Another option is to create an instance of the dictionary and add it manually to the current spell checker. Here is how this can be done:
I hope this is helpful. You can also check out this
article (again by Glenn) where the application partitioning is implemented with the use of DeploymentCatalog.
Please don't hesitate to get back to us if you have more questions.
