Is there a way to programmatically access the datasource or collection retrieved by the CMSViewer in a code-behind?

There doesn't seem to be an accessible DataSource property, and it's DataBinding event doesn't seem to pass this information via it's event arguments in the way typical databinding would--thought it is clear that databinding is being used due to the working databinding expressions we have in our ASCX transformation that is applied to it.

I am trying to access this information in any way possible, be it via properties or an event model... any input? Am I simply missing something?

Thanks much, in advance.
