Exceptions

Exception	Condition
System NullReferenceException	if an added Control does not have a Tag property defined.
System ArgumentException	if a pattern attribute has an invalid regular expression.
System FormatException	if any of the attributes that take numbers do not have a numerical argument.

Remarks

Each added control must have a Tag property as described in the class description, otherwise a NullReferenceException will be thrown. Once all form controls to be validated are added with this method, then call ValidateAll to validate all initial values, activate/deactivate error messages, and disable/enable the form's OK button. The OK button will only be enabled if all validated fields pass validation.
