Occurs before saving changes made to a specified persistent object to the database.
event EventHandler<ObjectManipulatingEventArgs> ObjectSaving
Event ObjectSaving As EventHandler(Of ObjectManipulatingEventArgs)
The ObjectSaving event handler receives an argument of the ObjectManipulatingEventArgs type. The following properties provide information specific to this event.
|Object||Provides access to the object that is being manipulated.|
Raise this event before saving changes made to the object passed as the handler's ObjectManipulationEventArgs.Object parameter.
When implementing the IObjectSpace interface in the BaseObjectSpace class' descendant, you don't have to declare this event. It's declared within the BaseObjectSpace class. The BaseObjectSpace.OnObjectSaving method raises this event. So, you should only invoke the OnObjectSaving method before an object is saved.
The object changes which are about to be saved to the database are the changes made after the last call of the IObjectSpace.CommitChanges method.
