Examples

The following example shows how to use a KeyBinding to bind a KeyGesture to a RoutedCommand. When the KeyGesture ALT+L is pressed, the Close command is invoked.

<KeyBinding Modifiers="Alt"
            Key="L"
            Command="ApplicationCommands.Close" />

KeyGesture CloseCmdKeyGesture = new KeyGesture(
    Key.L, ModifierKeys.Alt);

KeyBinding CloseKeyBinding = new KeyBinding(
    ApplicationCommands.Close, CloseCmdKeyGesture);

this.InputBindings.Add(CloseKeyBinding);

Dim CloseCmdKeyGesture As New KeyGesture(Key.L, ModifierKeys.Alt)

Dim CloseKeyBinding As New KeyBinding(ApplicationCommands.Close, CloseCmdKeyGesture)

Me.InputBindings.Add(CloseKeyBinding)

Remarks

The input gesture is the action that invokes the command. Examples of input gestures in WPF are KeyGesture and MouseGesture. A KeyGesture is a combination of a Key and a set of ModifierKeys. A MouseGesture is a combination of a MouseAction and a set of ModifierKeys.

The InputBinding class itself does not support XAML usage, because it does not expose a public parameterless constructor (there is a parameterless constructor, but it is protected). However, derived classes can expose a public constructor and thus can set properties that are inherited from InputBinding with a XAML usage. Two existing InputBinding derived classes that can be instantiated in XAML and can set properties in XAML are KeyBinding and MouseBinding.
