In WPF,MVVM should ViewModel be involved in opening a window, e.g. About-window?

问题 I have a standard WPF treeview and have bound items to view model classes. I now wish to handle behaviour when items are double-clicked (opening documents visual-studio-style). I can get event-handler to fire in the control housing the treeview (xaml shown), but how do I bind to specific behaviour on the view model classes - e.g. ProjectViewModel? Preferable bound to ICommand-implementer, as this is used elsewhere... Thanks for any comments, Anders, Denmark <TreeView ItemsSource="{Binding
