21 | ASP.NET renders a checkbox and a hidden input for each boolean property. 22 | The hidden input is used to ensure that a value is sent for the checkbox, 23 | even if it is unchecked. Unchecking it should not fail validation. 24 |
38 | One can also use the [Remote] validation attribute with checkboxes. 39 | This checkbox's remote validator returns valid only when it matches the one above. 40 | Note: Changes to 41 | additional fields 42 | do not automatically revalidate. 43 |
