CommandManager::RequerySuggested Event

 

Occurs when the CommandManager detects conditions that might change the ability of a command to execute.

Namespace:   System.Windows.Input
Assembly:  PresentationCore (in PresentationCore.dll)

public:
event EventHandler^ RequerySuggested {
	static void add(EventHandler^ value);
	static void remove(EventHandler^ value);
}

Since this event is static, it will only hold onto the handler as a weak reference. Objects that listen for this event should keep a strong reference to their event handler to avoid it being garbage collected. This can be accomplished by having a private field and assigning the handler as the value before or after attaching to this event.
