asp.net mvc: why is Html.CheckBox generating an additional hidden input

Question

I just noticed that Html.CheckBox(\"foo\") generates 2 inputs instead of one, anybody knows why is this so ?

Answer 1

You can try to initialize the constructor of your Model like that :

public MemberFormModel() {
    foo = true;
}

and in your view :

@html.Checkbox(...)
@html.Hidden(...)
