Namespace: DevExpress.ExpressApp.Xpo

Assembly: DevExpress.ExpressApp.Xpo.v23.1.dll

NuGet Package: DevExpress.ExpressApp.Xpo


public static IObjectSpace FindObjectSpaceByObject(
    object obj


Name Type Description
obj Object

The object whose Object Space must be determined.


Type Description

An IObjectSpace object which represents the Object Space used to load and save the specified persistent object. null (Nothing in VB.NET) if the specified object belongs to an XPO Session not managed by the ObjectSpace class.


This method is for internal use. It can access certain Object Spaces XAF uses internally (for example, the Object Space used by the Security System). Do not use such Object Spaces in your applications because this may cause unexpected behavior. Instead of this, implement the approaches below.

  • Within the object’s class code, use Session and its methods instead of an Object Space.

  • In other scenarios, create a new Object Space and use the GetObject(Object) method to retrieve an object in the current Object Space. Refer to the method’s description to see an example.
