Specifies how conditional expressions defined by an System.Web.UI.VerificationAttribute instance are used in verification.
Syntax
Remarks
When using extending a class, member or indexer with a System.Web.UI.VerificationAttribute, you may define how the conditional expression, defined by the VerificationAttribute.ConditionalProperty and VerificationAttribute.ConditionalValue properties, is used by specifying one of the System.Web.UI.VerificationRule values. If in the creation of the System.Web.UI.VerificationAttribute no System.Web.UI.VerificationRule is specified, the default value of VerificationRule.Required is used.
The left side of a verification rule's conditional expression is the VerificationAttribute.ConditionalProperty and the right side is the VerificationAttribute.ConditionalValue. The System.Web.UI.VerificationConditionalOperator specifies how the VerificationAttribute.ConditionalProperty is to be compared to the VerificationAttribute.ConditionalValue.
