Convert bool to bool? in @Html.CheckBoxFor() call in ASP.NET MVC

Question

I am attempting to retrieve the bool value from the CheckBox and assign it to the variable m.IsAdministrator, which is of type bool?:

@Html.CheckBoxFor(m => (bool?)(m.isAdministrator))

However, this syntax gives an error. How can I assign the bool CheckBoxFor return value to a bool??

Answer 1

@Html.CheckBoxFor(m => m.isAdministrator.Value)

And be sure to check that it has value before or you'll get exception.

However, using nullable in view model is not a best practice.
