I'm playing with MVC3 using the Razer syntax, though I believe the problem to be more general.
In the controller, I have something like:
ViewModel.User = New User(); // The model I want to display/edit
ViewModel.SomeOtherProperty = someOtherValue; // Hense why need dynamic
Return View();
My View inherits from System.Web.Mvc.ViewPage
But if I try to do something like:
<p>
@Html.LabelFor(x => x.User.Name
@Html.EditorFor(x => x.User.Name
</p>
I get the error: "An expression tree may not contain a dynamic operation"
However, the use of ViewPage seems quite common, as are EditorFor/LabelFor. Therefore I'd be surprised if there's not a way to do this - appreciate any pointers.
