Generally, the array of items is auto-generated when a validation result is ready. And if you set a custom array of items, it will be overridden by the auto-generated array. So use this property to read the current array of items. Alternatively, you can set the array of items generated by a custom validation engine.
The ValidationSummary component evaluates the html property's value. This evaluation, however, makes the ValidationSummary potentially vulnerable to XSS attacks. To guard against these attacks, encode the HTML markup before you assign it to the html property. Refer to the following help topic for more information: Potentially Vulnerable API - html.
You can use the text property as a safe alternative.
The following types of the specified value are available.
