/*! \brief Raising an event invokes the event handler through a delegate.

* The \b OnMsgDataLoad 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.
* \note When overriding \b OnMsgDataLoad in a derived class, be sure to
* call the base class's \b OnMsgDataLoad method so that registered delegates
* receive the event. */
