Public Class CommandBinding

Inheritance: Object
CommandBinding

Remarks

A CommandBinding associates a command with the PreviewExecuted/Executed and PreviewCanExecute/CanExecute events which implement and determine the status of the command.

When the Execute or CanExecute method of a RoutedCommand is called, the PreviewExecuted/Executed or the PreviewCanExecute/CanExecute events are raised on the command target. If the command target has a CommandBinding for the command, the appropriate handlers are called. If the command target does not have a CommandBinding for the command, the events are routed through the element tree until an element that has a CommandBinding is found.

A CommandBinding has limited use with an ICommand that is not a RoutedCommand. This is because a CommandBinding binds the command to the ExecutedRoutedEventHandler and the CanExecuteRoutedEventHandler which listen to the Executed and CanExecute routed events which are raised when the Execute and CanExecute method of the RoutedCommand are called.
