Checkbox not working with boolean viewmodel property

Question

I am using MVC6 and have a checkbox input field in my form, but when the form is submitted the value for the checkbox always gets passed to the ViewModel as false:

Answer 1

input type checkbox sends an "on" if it is set. Otherwise it is not sent. It is important, that you set the value attribute to true. In this case it sends true or nothing, which is perfect to bind to a boolean.
