问题 I have a custom Control derived class and a view model to go with. The user can do several actions with this control, and I'm thinking it's best to implement these as RoutedCommand objects or ICommand derived objects in the view model so the ControlTemplates can bind to them. Binding a command to a button in one ControlTemplate should be straightforward, but how can I bind the command to e.g. the right mouse button in another ControlTemplate? Probably a MouseGesture is involved, but I'm

问题 I have a listbox that should display data that contains 2 fields: time and a message.
