KeyPressToCommand
Sometimes you need to handle a key press and convert it to a command. An excellent example is a ListBox that should respond to an Ctrl + Enter key press.
1) Add the following XML namespaces:
xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity" xmlns:catel="http://catel.codeplex.com"
2) Use the following definition:
<ListBox x:Name="listBox" ItemsSource="{Binding PersonCollection}" SelectedItem="{Binding SelectedPerson}"> <i:Interaction.Behaviors> <catel:KeyPressToCommand Command="{Binding MyCommand}" Key="Enter" Modifiers="Ctrl" /> </i:Interaction.Behaviors> </ListBox>
