Occurs before certain properties of the IPrintingSystem object are changed.
The BeforeChange event's data class is ChangeEventArgs. The following properties provide information specific to this event:
|EventName||Gets the event name that initiated a ChangeEvent.|
The event data class exposes the following methods:
|Add(String, Object)||Initializes a new instance of the DevExpress.XtraPrinting.ChangeEventArgs.EventInfo class with the specified name and value and adds it to the collection.|
|ValueOf(String)||Returns an object, containing information about the event with the specified name.|
The printing system provides several events which occur before specific properties are changed. Classes that implement this interface specify which properties should generate the BeforeChange event prior to the change.
