Html.Action asp.net mvc
I am working on a website (Asp.net mvc), where I have multiple partial views. One of the views is user information and then below there are few other views say books by the user, articles in a given book etc. thats how my controller looks like. 

    public controller UserController
    {

       public ActionResult UserInfo(long userid)
       {
            var model.User = LoadUser(userId);
            Retrun View(model);
       } 

       public ActionResult Books(long userId)
       {
            var model.User = LoadUser(userId);
            model.Books = LoadBooks(userId);
            
            Retrun View(model);
       } 

       public ActionResult Articles(long bookId)
       {
            var model.User = LoadUserByBookId(bookId);
            model.Book = LoadBook(bookId);
            model.Articles= LoadArticles(bookId);
           
            Retrun View(model);
       } 

    } 

I have created three partial views for UserInfo, Books and Articles and pass data from a given view. Now you can see with each method things go more complex. I was reading about Html.Action helper which can load individual partial views. But as you can see I need to pass some data from Html.Action helper to the methods so it can load data accordingly for example to load userinfo, I will need to pass userId. 

How can I achieve this using this or any other better method. Help will be appreciated.
