Programmatically (call) WorkItem Refresh functionality

Good afternoon,

is there a way to refresh an open WorkItem (tool)window inside VisualStudio 2012 from another VisualStudio Extension? Basically iterate over the open windows and search for a particular workitem and then refresh it?

I am asking because in our own tooling we do modify workitems but unfortunately if the user opened it manually out of a query or by 'Go'ing to it, it is not in the latest state once we changed it hence the user cannot save his/her changes in that toolwindow.

Therefore and in certain situations we'd like to trigger that Refresh from code automatically.

Is there any way to do that?

Thanks!
