form submit checkbox sets value to “on” rather than “true”
A checked checkbox simply sends its value attribute. An unchecked checkbox doesn’t send itself in the form. Therefore, a simple test if the checkbox’s name attribute was posted can determine if it was checked or not.
Html.CheckBox returns false if disabled, even if seleced
An input field marked with the disabled=”disabled” attribute NEVER sends its value to the server. If you want to achieve this you could use the readonly=”readonly” attribute which still prevents the user from modifying the value but sends the existing value when the form is submitted.

React checkbox doesn’t toggle
