scroll ListBox to bottom in xaml

[ausadmin]

I have been using the MVVM pattern extensively to build a UI (as in the great samples "WPF Apps With The Model-View-ViewModel Design Pattern"[^] and "Creating an Internationalized Wizard in WPF" [^]. This is a great technique for UI development, and I thank Josh Smith and Karl Shifflett for their postings and assistance in this area. While I have now got most of this working really well, I have hit a problem that I can't figure out how to solve in xaml or with data binding. I have a ListBox which I can add items to, but as the number of items exceeds the size of the ListBox, the items added at the bottom scroll out of view... I want to have the ListBox automatically scroll to display the last item. Can anyone tell me how to do this in xaml? I have reviewed several posts regarding use of the ScrollIntoView method, but I do not know how to access this from xaml (I think it may not be possible as its a method). As this is using the MVVM pattern, there is no way (that I am aware of) to access the ListBox instance from the code, to be able to call ScrollIntoView. Another solution would be to scroll to item n in xaml, which would be fine because I could then data bind to n. However I also have not been able to find a way to control the scrolling in xaml. I'm realy surprised there seems to be no easy way to do this in xaml. Any help would be greatly appreciated. Thanks, Tim
