in chapter 5 it is explained how to set particular error for a specific field when it is invalidated.it uses ModelState.AddModelError in the controller. but something is wrong with this an that is such error is displayed always even before submitting the formso if one want to create a specific error for a specific field what he must do?

furthermore I couldn't find where the error text for a field has been set?
THANK YOU!

What page, and where on that page?

in the page 123.

I looked at it and I didn't see a problem - I would have to go back and follow writing the code to see what you are asking. Sorry! I may do that after I finish the book. That is probably too late for you.

I guess I am the wrong person to help you. Did you look at the downloaded code? Does that help? Maybe see if someone has encountered this on Stack Overflow or some other place if this doesn't help. Sometimes the MSDN tutorials and Question and Answer can help.
