In 18.2.2, the custom validation code does not execute if the [lastname] field is merely tabbed out of, limiting the validity of the code given as a "required field" check - apparently, the setter is never called in this case either.

So, perhaps this should be brought up in the transition paragraph and I shoul read on... smilie

18.4 has that and more problems: If I enter 100 for "level," it get's flagged with an error, since the "salary" has not yet been set to a valid value. If I then enter 60,000, a valid "salary" for that "level," the error is still left showing on "level."

I took care of the problem in this manner:

if (isValid)
if (_dataErrors.ContainsKey("Level"))
if (_dataErrors.ContainsKey("Salary"))
... else

It seems a NotifyPropertyChanged event is needed to clear the error UI.
