WPF快捷键绑定

Question

I want to bind a shortcut key to my usercontrol using UserControl.InputBindings.

I am not using MVVM or any other pattern. I just want to bind this key using the code behind file of a XAML file.

Answer 1

You can do key binding like this in XAML:

<UserControl.InputBindings>
    <KeyBinding Command="{Binding SomeCommand}" Key="F5"/>
</UserControl.InputBindings>

Answer 2

If you want to assign a keybinding, and you want to do it from the code-behind, this would be the easiest way:

using System.Windows.Input;

var cmd = new RoutedCommand();
userControl.InputBindings.Add(new KeyBinding(cmd, your_key_gesture_here));
userControl.CommandBindings.Add(new CommandBinding(cmd, your_event_handler_here));

Replace your_key_gesture_here with the shortcut key you want to trigger, and replace your_event_handler_here with the method you want to be triggered when the key is pressed.
