Binding. Preview Can Execute Event
Occurs when the command associated with this CommandBinding initiates a check to determine whether the command can be executed on the current command target.

member this.PreviewCanExecute : System.Windows.Input.CanExecuteRoutedEventHandler
Public Event PreviewCanExecute As CanExecuteRoutedEventHandler
When the CanExecute method on a RoutedCommand is called, the PreviewCanExecute event is raised on the command target if the command target has a CommandBinding for the command. Then the CanExecute handler for that CommandBinding is called. If the command target does not have a CommandBinding for the command, the CanExecute event bubbles up the element tree searching for an element that has a CommandBinding associated with the command. If the event is not handled, the CanExecute event is raised.
