CompositeObjectSpace.AutoRefreshAdditionalObjectSpaces Property
Specifies whether the current Object Space refreshes its inner Object Spaces from the AdditionalObjectSpaces collection when it refreshes itself.
Namespace: DevExpress.ExpressApp
Assembly: DevExpress.ExpressApp.v23.2.dll
NuGet Package: DevExpress.ExpressApp
Declaration
Property Value
| Type | Description |
|---|---|
| Boolean | true, if the current Object Space refreshes its inner Object Spaces from the AdditionalObjectSpaces collection when it refreshes itself; otherwise, false. The default value equals the AutoRefreshAdditionalObjectSpacesByDefault static field’s value. |
Remarks
If a non-persistent object contains a reference to or a collection of persistent objects, you need to refresh their Object Space after refreshing the parent non-persistent Object Space. Set this property to true to do this automatically each time the non-persistent Object Space refreshes.
After refreshing, drop all references and collections of outdated persistent objects and create new instances in refreshed persistent Object Spaces. Also, you can drop the non-persistent object with persistent objects it references and create a new instance again in the ObjectsGetting, ObjectGetting, and ObjectByKeyGetting event handlers.
Refer to the following GitHub example to see how to use this property: How to refresh Non-Persistent Objects and reload nested Persistent Objects.
