provides data for a event. The event notifies the and registered event handlers that a particular component in the currently active document has been changed.

A provides the following information:

A property that indicates the component that was modified.

A property that indicates the member that was changed.

A property that indicates the new value of the member.

An property that indicates the old value of the member.

Component designers typically raise the event automatically when components are added, removed, or modified. A event is not raised during form load and unload because changes at this time are expected. A component designer might raise the event after it changes a property of the component; this ensures that the Properties window will display the updated property.

Provides data for the event. This class cannot be inherited.
