Component.CanRaiseEvents Component.CanRaiseEvents Component.CanRaiseEvents Component.CanRaiseEvents Property

Definition

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

protected:
 virtual property bool CanRaiseEvents { bool get(); };
protected virtual bool CanRaiseEvents { get; }
member this.CanRaiseEvents : bool
Protected Overridable ReadOnly Property CanRaiseEvents As Boolean
Property Value

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

Remarks

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 CanRaiseEvents 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 Events property returns null for an event. Events can still be added and removed from the collection, but the collection's Item[Object] property will always return null.
