Rendering Html.Hidden helper with custom value

Question

I have the following razor markup:

@{
    var initValue = @Html.Raw(new JavaScriptSerializer().Serialize(Model));
    @Html.Hidden("initial-namings-data", initValue.ToString());
}

It gives me error:

'System.Web.Mvc.HtmlHelper' has no applicable method named 'Hidden' but appears to have an extension method by that name. Extension methods cannot be dynamically dispatched. Consider casting the dynamic arguments or calling the extension method without the extension method syntax.

How can I fix it? Thanks.

What is the type of `Model`? dynamic? – nemesv Jul 28 '12 at 14:25 — nemesv, Jul 28 '12 at 14:25
Yes, the view's Model is not strongly typed. – Maxim V. Pavlov Jul 28 '12 at 18:17 — Maxim V. Pavlov, Jul 28 '12 at 18:17

The problem might be that the compiler cannot choose the correct type.

Try changing it too:

@Html.Hidden("initial-namings-data", (string)initValue.ToString());
