IsCommandManagerRequerySuggestedEnabled

Controls whether the command's CanExecuteChanged is attached to the RequerySuggested event.

Declaration
bool IsCommandManagerRequerySuggestedEnabled { get; set; }
Property Value
Type Description
Boolean

true to attach the CanExecuteChanged is attached to the RequerySuggested event.
The default is true.
Remarks

If the IsCommandManagerRequerySuggestedEnabled property is set to true, calling the InvalidateRequerySuggested() method will also raise the CanExecuteChanged event.
This is the default behavior. InvalidateRequerySuggested() is regularly invoked by the framework to keep UI elemnts, that implement ICommandSource (like the Button control) and listen to the CanExecuteChanged event, updated.
When the IsCommandManagerRequerySuggestedEnabled property ios set to false, the CanExecuteChanged must be raised explicitly by calling the InvalidateCommand() method.
