OnInteractiveRegionTypeChanged Method
Summary
Raises the InteractiveRegionTypeChanged event.
Syntax
protected virtual void OnInteractiveRegionTypeChanged(EventArgs e)
Protected Overridable Sub OnInteractiveRegionTypeChanged( _ByVal e As EventArgs _)
protected:virtual void OnInteractiveRegionTypeChanged(EventArgs^ e)
Parameters
e
An EventArgs that contains the event data.
Remarks
Raising an event invokes the event handler through a delegate. The OnInteractiveRegionTypeChanged 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 OnInteractiveRegionTypeChanged in a derived class, be sure to call the base class's OnInteractiveRegionTypeChanged method so that registered delegates receive the event.
