Occurs before an object is deleted from the data source.
Assembly: System.Web.Entity (in System.Web.Entity.dll)
The event is raised before the SaveChanges method is called on the ObjectContext to delete an object. The Entity property of the EntityDataSourceChangingEventArgs object is used to access the object to be deleted. The properties of this object may not be fully set. Only the properties required to identify the object must be set.
When you handle the exception in the event handler, set the ExceptionHandled property to true. This prevents the exception from being raised again. When you specify a value of false for the ExceptionHandled property, the EntityDataSource re-raises the exception.
