your model object must be of the same type as the object in the choices list
ie
DropDownChoice<T>(WebMarkupContainer, String, IModel<T>, IModel<List<T>>,
IChoiceRenderer<T>)
so if your model is String then the list of choices you pass in must be
List<String>

Hi,johan
y, your right, the column id is string object, render is always get a

I first use expression for default Render, and get the same error.
show you the complete stacktrace
