EFObjectSpace.IsNewObject Method

Indicates whether a specified object has been created but has not been saved to the database.

Namespace:DevExpress.ExpressApp.EF
Assembly:DevExpress.ExpressApp.EF.v19.1.dll

Expanded Syntax

Parameters

obj
Type: Object
An object to be tested.

Return value

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

Expanded Remarks

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 does not belong to the current Object Space.
