Nadya,

You're welcome. My point is simply that you could provide the same ease of entry using another control that would provide for better validation for you.

You could create a container class with a fixed number of textboxes that have their borders turned off and it would look exactly like the editbox without scrollbars in it but each textbox would fire its valid with one discrete value in it for you to check. If all the textobxes needed the same validation you could easily add a method to the container and have each textbox call teh containers method from its own valid.

Why bother, well the users lkike the editbox look adn feel and the textbox is easier to maintain and validate the values with, so combine and get the best of both worlds.
