Being "in error" is the state of the object in question; not a flag or entry in a list. That's transaction oriented versus "online".

My "HasErrors" runs all the "validations" on the object and returns true or false anytime it is called (e.g. before saving). No "error lists" to clear etc.

You can also retrieve all errors (to show only the first, for example, to avoid overloading thee user).

At the same time, all the textboxes in error are "red lined" as expected.


"Before entering on an understanding, I have meditated for a long time, and have foreseen what might happen. It is not genius which reveals to me suddenly, secretly, what I have to say or to do in a circumstance unexpected by other people; it is reflection, it is meditation." - Napoleon I
