RoutedCommand RoutedCommand RoutedCommand RoutedCommand Class

Definition

Defines a command that implements ICommand and is routed through the element tree.

public ref class RoutedCommand : System::Windows::Input::ICommand
[System.ComponentModel.TypeConverter("System.Windows.Input.CommandConverter, PresentationFramework, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, Custom=null")]
[System.ComponentModel.TypeConverter("System.Windows.Input.CommandConverter, PresentationFramework, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, Custom=null")]

Remarks

The Execute and CanExecute methods on a RoutedCommand do not contain the application logic for the command as is the case with a typical ICommand, but rather, these methods raise events that traverse the element tree looking for an object with a CommandBinding. The event handlers attached to the CommandBinding contain the command logic.

The Execute method raises the PreviewExecuted and Executed events. The CanExecute method raises the PreviewCanExecute and CanExecute events.
