• PersistentBase.GetModificationsStore(Object)

Remarks

To access a IXPModificationsStore storage for a given persistent object, use the static PersistentBase.GetModificationsStore method. Then, you can access the IXPModificationsStore methods. For example:

C#

XPMemberInfo miContactTitle = person.ClassInfo.GetMember("ContactTitle");
IXPModificationsStore ms = PersistentBase.GetModificationsStore(person);
var oldValue = ms.GetPropertyOldValue(miContactTitle);

VB.NET

Dim miContactTitle As XPMemberInfo = person.ClassInfo.GetMember("ContactTitle")
Dim ms As IXPModificationsStore = PersistentBase.GetModificationsStore(person)
Dim oldValue = ms.GetPropertyOldValue(miContactTitle)
