I have a business rule on a date property that needs to throw a verification exception on change only if the previous date in the property is before the current date.  How would you access the previous value?

Thanks,
Mike

I think I have it now. I am using the

VerifierExecutionModes.InstanceAndOnPresetTriggers

and the

TriggerContext.ProposedValue
