Assembly: DevExpress.Xpo.v20.1.dll

NuGet Packages: DevExpress.WindowsDesktop.Xpo, DevExpress.Xpo

Declaration

C#
VB.NET

[NonPersistent]
[MemberDesignTimeVisibility(false)]
[OptimisticLocking(true)]
public abstract class XPBaseObject :
    PersistentBase,
    IEditableObject,
    ICustomTypeDescriptor,
    IComparable,
    IXPReceiveOnChangedFromXPPropertyDescriptor

<NonPersistent>
<MemberDesignTimeVisibility(False)>
<OptimisticLocking(True)>
Public MustInherit Class XPBaseObject
    Inherits PersistentBase
    Implements IEditableObject,
               ICustomTypeDescriptor,
               IComparable,
               IXPReceiveOnChangedFromXPPropertyDescriptor

Remarks

The XPBaseObject class automatically supports the optimistic concurrency feature. If this feature is not required, you can use the XPLiteObject class instead.

When creating a persistent object by deriving from the XPBaseObject, XPCustomObject or XPObject class, an OptimisticLockingAttribute is automatically applied to it. This attribute specifies whether a session can lock a persistent object’s state (allows optimistic locking to be enabled). For more information, see XPObject and Optimistic Concurrency.
