This enhancement allows specifying
selective partial validation in a web form using validation controls. Each
validation group is evaluated separately from other validation groups in the
web form. You can specify Validation Groups by setting the Validation Group
Property of Validation Controls to a value. All the Validation Controls with
the same value set for the Validation Group property are included in the same
Validation Group.
