commandbinding

I looked over this web and google and the solutions didn't work for me. I have a command on the ViewModel of a UserControl. Well, The usercontrol have a ItemsControl binded to a ObservableCollection. Inside the DataTemplate of the ItemsControl.ItemTemplate I have a button and I want to use the command.

Grokys You can do this in xaml - see the example in the documentation for the KeyBinding class: <Window.InputBindings> <KeyBinding Command="ApplicationCommands.Open" Gesture="CTRL+R" /> </Window.InputBindings> Update: Looks like you can't actually bind a KeyBinding to a ViewModel using just xaml if you're
