Namespace: DevExpress.Persistent.BaseImpl

Assembly: DevExpress.Persistent.BaseImpl.Xpo.v23.2.dll


public static OidInitializationMode OidInitializationMode { get; set; }

Property Value

Type Description

An OidInitializationMode enumeration value specifying when a new GUID value is assigned to the Oid property.


In OidInitializationMode.AfterConstruction mode, the unique object identifier is immediately assigned to a newly created object. In OidInitializationMode.OnSaving mode, the unique identifier is assigned to a newly created object when the object is saved.

The Solution Wizard generates new projects with the FrameworkSettings.DefaultSettingsCompatibilityMode property set to Latest. This sets the OidInitializationMode property value to AfterConstruction using the following code line added to the ModuleBase constructor in the Module.cs (Module.vb) file:

BaseObject.OidInitializationMode = OidInitializationMode.AfterConstruction;

The following code snippets (auto-collected from DevExpress Examples) contain references to the OidInitializationMode property.
