ASP.NET MVC return ViewResult

Question

I trying to return a ViewResult in OnActionExecuted method override from ActionFilterAttribute class.Like below:

  public override void OnActionExecuted(ActionExecutedContext filterContext)
    {

        if (CreateCookie && filterContext.Exception == null)
        {
            LoginCookies lcookie = new LoginCookies(usuDs, usuSenha);
            lcookie.WriteCookie("SCE", 10);
        }
        else
        {
            filterContext.Result = new ViewResult() { ViewName = "Login" };
            filterContext.Result.ExecuteResult(filterContext.Controller.ControllerContext);
        }

It works fine to return to a view called "Login",but i need to pass the model object to this view (in this case model object is type of Users) and i dont know how to pass it using ViewResult class directly.

Any ideias?

UPDATED: Ive solved my problem setting filteContext.ExceptionHandled to TRUE,but the main problem was not solved,i cant set MODEL property of View,it is always null.

I may be mistaken, but I believe that the view data is part of the controller base and not actually part of the view itself. So you should be able to set the view data by doing such:

filterContext.Controller.ViewData.Model = <your view model>

I just tested and this worked for me. I don't see any reason why it shouldn't work for you:

public override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        TestClass1 viewModel = new TestClass1();

        viewModel.FirstName = "TestFilter";

        filterContext.Controller.ViewData.Model = viewModel;
    }

Maybe this will work for you:

filterContext.Result = new ViewResult { ViewName = "Exception", ViewData = new ViewDataDictionary(new CmsExceptionViewData(filterContext.Exception, action, controllerName, errorMessage)) };

So the ViewData is created with a ViewDataDictionary which accepts either a dictionary or a model.
