member this.CommandTarget : System.Windows.IInputElement with get, set

Public Property CommandTarget As IInputElement

Property Value

IInputElement

The target of the command. The default is null.

Remarks

In the Windows Presentation Foundation commanding system, the CommandTarget property on an ICommandSource object is applicable only when the ICommand is a RoutedCommand. If the CommandTarget is set on an ICommandSource and the corresponding command is not a RoutedCommand, the command target is ignored.

When used with a RoutedCommand, the command target is the object on which the Executed and CanExecute events are raised. If the CommandTarget property is not set, the element with keyboard focus is used as the target.

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 therefore 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.

XAML Attribute Usage

<inputBindingDerivedClass CommandTarget="bindingToTarget"/>
