IObjectSpaceLink Interface

Implemented by business classes that provide a reference to an associated Object Space.

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

Expanded Syntax

Expanded Remarks

You can use the XAF Business Object | EF Business Object from Template Gallery to add a class that supports both IXafEntityObject and IObjectSpaceLink. To support IObjectSpaceLink in an existing class, use the following code.

An Object Space reference is automatically assigned to the ObjectSpace property when a business object supporting IObjectSpaceLink is created using IObjectSpace methods. All data manipulations are preformed using these methods in internal XAF code, and it is recommended to use IObjectSpace in your custom code as well. You can implement this interface and access other business objects directly in the current object code. For example, you can write certain business logic in the IXafEntityObject.OnCreated, IXafEntityObject.OnLoaded and IXafEntityObject.OnSaving methods, as demonstrated in the IXafEntityObject interface description.

Note

The Object Space reference is set to null (Nothing in VB) when an object is being deleted.
