Checkbox and Hidden field in ASP.NET MVC

Html.CheckboxFor generates hidden field with false value and it is reasonable. But now I need to implement form with GET HTTP method. Obviously true AND false values are being sent to the server when I submit my form. the problem is that MVC model binder cannot understand "true,false" value.

The parameter conversion from type 'System.String' to type 'System.Boolean' failed. 
See the inner exception for more information.

How can I workaround this issue?

Solution

Actually the problem was in MvcContribGrid.

See question: MvcContrib grid and checkboxes

It combines query string values http://contoso.com?CheckBoxVal=true,CheckBoxVal=false into http://contoso.com?CheckBoxVal=true,false

Is there a faster way to tell which element is the problem when ModelState.IsValid is false other than iterating through every element?
