Namespace: DevExpress.ExpressApp

Assembly: DevExpress.ExpressApp.v18.2.dll

Declaration

event EventHandler<ObjectsManipulatingEventArgs> ObjectDeleting
Event ObjectDeleting As EventHandler(Of ObjectsManipulatingEventArgs)

The ObjectDeleting event handler receives an argument of the ObjectsManipulatingEventArgs type. The following properties provide information specific to this event.

Property Description
Objects Provides access to the objects that are being manipulated.

Raise this event before objects are marked as deleted from a dataset (see BaseObjectSpace.Delete). Use the handler's ObjectsManipulatingEventArgs.Objects parameter to get the object(s) to be deleted.

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. In addition, the BaseObjectSpace.OnObjectDeleting method raises this event. So, you should only invoke the OnObjectDeleting method before objects are marked as deleted.
