Hi there, Depending on the format of a date value which you want to validate, you can choose an appropriate regular expression for the ValidationExpression property of the RegularExpressionValidator. You can see some patterns from here Regular Patterns[^] or Google can give you a bunch. In addition to RegularExpressionValidator, you can simply use a CompareValidator[^] to do that, set the Type property to Date and the Operator to DataTypeCheck. However, you also should remember that this validator is Culture sensitive, the regular expression used by the CompareValidator depends on the current CultureInfo value. You can also use a CustomValidator[^]with which you can provide your own logical business to validate a date value.
