Public ReadOnly Property OldValue As Object

Property Value

Type	Description
Object	The old value of a changed property.

Remarks

The IObjectSpace.ObjectChanged event can be triggered when an end-user starts modifying any property value in a UI. In this instance, the event is triggered, but the ObjectChangedEventArgs.NewValue and OldValue properties are equal. This is the designed behavior. So, if you want to execute a custom activity when a property value change occurs, check the equality of these properties preliminarily.
