IObjectSpace.IsNewObject Method

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

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

Expanded Syntax

Parameters

obj
Type: Object
A object to be tested.

Return value

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

Expanded Remarks

The objects that are created both directly via the 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 CommitChanges method is called, directly or by means of 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. It is presumed that this property must return false if the object passed as the parameter is not persistent, or if it does not belong to the current Object Space.
