Question

Is it possible to assign an Lambda Expression (action?) to a property of my View Model, then use that expression in a Partial? What should the model’s property type be? Psuedo Code:

View Model

public class MyModel
{
    public ????? MyAction {get;set;}
}

Controller

public ActionResult Index()
{
   var model = new MyModel();
   model.MyAction = ?????<MyController>(x => x.DoThis());

   return View(model);
}

public ActionResult DoThis()
{
   return View();
}

Partial.ascx, How would I assign the action to the ActionLink?

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<MyModel>" %>

<%=Html.ActionLink<Controller>(x => x.DoThis())%>

I am using the strongly typed ActionLink from the Futures assembly.

Try this:

public class MyModel
{
    Expression<Action<MyController>> Action { get; set; }
}

...

model.Action = x => x.DoThis();

...

<%= Html.ActionLink( Model.Action ) %>
