Assembly: DevExpress.ExpressApp.Xpo.v18.1.dll

Syntax

public override bool IsNewObject(
    object obj
)

Parameters

Type Name Description
Object obj

A object to be tested.

Returns

Type Description
Boolean

true if the specified object has not been yet saved to the database; otherwise, false.

The objects that are created both directly via the BaseObjectSpace.CreateObject method and by means of built-in Actions (e.g. the New Action) are not saved to the database immediately. They are saved only when the BaseObjectSpace.CommitChanges method is called, directly or by means of the built-in Actions (e.g. the Save Action). Until an object created within the current Object Space is not saved to the database, the IsNewObject method returns true. After saving, the IsNewObject method returns false. In addition, it returns false, if the object passed as the parameter is not persistent, or if it does not belong to the current Object Space.
