System.MissingMethodException: No parameterless constructor defined for this object

Question

I\'m using MVC 2.0 with a Html.ListBoxFor as below:

<% using (Html.BeginForm()) { %>

       \" />

        <%=         


        

Answer 1

Does your LogOnModel have a parameterless constructor? It needs one for the DefaultModelBinder to instantiate it. Additionally, when you post the exception, please post the full stack trace from the exception object, else we're simply guessing where the error actually took place.
