Hi...

I have a home screen in which I have header footer and some content. In the content area, I am rendering login control as a partial view. Now I am trying to provied validations to login control. Here is code of my surface controller for login 

 [HttpPost]
        [ActionName("Login")]
       public ActionResult Login(LoginCommand command)
       {
           if (ModelState.IsValid)
           {
               if (Membership.ValidateUser(command.Username, command.Password))
               {
                   FormsAuthentication.SetAuthCookie(command.Username, command.RememberMe);
                   if (command.RememberMe)
                   {
                       Response.Cookies["UserName"].Value = command.Username;
                       Response.Cookies["Password"].Value = command.Password;
                   }
                   return PartialView("Details", command);              
               }
               else
               {
                   ModelState.AddModelError("Login", "Invalid username or password");
                   return PartialView("Login", new LoginCommand());
               }
           }
           return PartialView("Login", new LoginCommand());
       }

But when I return partial view with error, it is being rendered in a new page, not in the same location( in the home page). How should we render the view with error state in the home screen also by preserving model state?
