Property Value

Type: System::Boolean

true if the event can be executed on the command target; otherwise, false. The default value is false.

Many command sources, such as MenuItem and Button, are disabled when CanExecute is false and enabled when the CanExecute is true.

The follow example creates a CanExecuteRoutedEventHandler that only returns true if the command target is a control. First the Source event data is cast to a Control. If it is a Control, CanExecute is set to true; otherwise, it is set to false.

No code example is currently available or this language may not be supported.
