Raises the MouseEnter event.
[Visual Basic] Protected Overridable Sub OnMouseEnter( _ ByVal e As EventArgs _ ) [C#] protected virtual void OnMouseEnter( EventArgs e ); [C++] protected: virtual void OnMouseEnter( EventArgs* e ); [JScript] protected function OnMouseEnter( e : EventArgs );
- An EventArgs that contains the event data.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The OnMouseEnter method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors: When overriding OnMouseEnter in a derived class, be sure to call the base class's OnMouseEnter method so that registered delegates receive the event.
