Gets a value indicating whether the component can raise an event.

Namespace:   System.ComponentModel
Assembly:  System (in System.dll)

protected virtual bool CanRaiseEvents { get; }
property bool CanRaiseEvents {
	virtual bool get();
abstract CanRaiseEvents : bool with get
override CanRaiseEvents : bool with get
Protected Overridable ReadOnly Property CanRaiseEvents As Boolean

Property Value


true if the component can raise events; otherwise, false. The default is true.

The default implementation of this property always returns true. Classes that inherit from the Component class should override this property to provide the ability to disable the raising of events. For example, in the Control class, if the control is being hosted as an ActiveX control, the property returns false if the ActiveX control has its events frozen.

Notes to Inheritors:

If you override this method in a deriving class and change it to return false, the EventHandlerList collection returned by the property returns null for an event. Events can still be added and removed from the collection, but the collection's property will always return null.
