Hide regular expression validations in a winpart

If I understand you correctly, you just need to create a custom rule for a property that understands that no value is a valid value.  Is this what you are looking for?

Hi,

I have a winpart with an errorProvider bound to a bindingsource. When I run the application, in the winpart, the business validation rules appear like an icon next to the control. It's perfect, but I just need that this icons appear for the required validation rules when a winpart start. In this instance, I don't need that appear the regular expression validation.

The behavior that I'm looking for is like a form with an email field. I just need that an error appear when I wrote something wrong in the control bound to the email field, but if the control hasn't a value, no problem, the error doesn't appear.

Somebody knows How can I get this behavior?

Regards...
