  • Reference

Definition

Namespace:
System.Windows.Input
Assembly:
PresentationCore.dll

public:
 int Add(System::Windows::Input::InputBinding ^ inputBinding);
public int Add (System.Windows.Input.InputBinding inputBinding);
member this.Add : System.Windows.Input.InputBinding -> int
Public Function Add (inputBinding As InputBinding) As Integer

Parameters

inputBinding
InputBinding

The binding to add to the collection.

Returns

Int32

Always returns 0. This deviates from the standard IList implementation for Add, which should return the index where the new item was added to the collection.

Exceptions

NotSupportedException

inputBinding is null.

Examples

The following example creates a KeyGesture and associates it with a KeyBinding. The KeyBinding is added to the InputBindingCollection on a Window.

<Window.InputBindings>
  <KeyBinding Key="B"
              Modifiers="Control" 
              Command="ApplicationCommands.Open" />
</Window.InputBindings>

KeyGesture OpenKeyGesture = new KeyGesture(
    Key.B,
    ModifierKeys.Control);

KeyBinding OpenCmdKeybinding = new KeyBinding(
    ApplicationCommands.Open,
    OpenKeyGesture);

this.InputBindings.Add(OpenCmdKeybinding);

Dim OpenKeyGesture As New KeyGesture(Key.B, ModifierKeys.Control)

Dim OpenCmdKeybinding As New KeyBinding(ApplicationCommands.Open, OpenKeyGesture)

Me.InputBindings.Add(OpenCmdKeybinding)

The XAML example does not literally use Add, but Add is called implicitly by the XAML processing support for collections. For details on XAML and collections, see XAML Overview (WPF).
