I've got this task requiring building a parent/child view in html. NOT USING ANY PLUGINS!
I've created a database and a model (H_Table), and a class (Element) in controller for child nodes. But how do I get this to work together. So, that it retrieves data from the model passes it to the class and returns to view as model. I'm not really sure whether I explaied it right. Ask away.
My Model:
namespace Tree_List.Models
{
using System;
using System.Collections.Generic;
public partial class H_Table
{
public int ID { get; set; }
public string NAME { get; set; }
public Nullable<int> PARENT_ID { get; set; }
}
}
My Controller:
using System.Collections.Generic;
using System.Web.Mvc;
using Tree_List.Models;
namespace Tree_List.Controllers
{
public class ListController : Controller
{
// GET: List
private Models.ListDBEntities1 db_connection = new Models.ListDBEntities1();
public ActionResult Index()
{
var Items = db_connection.H_Table;
return View(Items);
}
}
public partial class Element
{
public int ID { get; set; }
public string NAME { get; set; }
public List<Element> CHILDS { get; set; }
}
}
If I get your question right you want to render this hierarchical data of yours in a view. To do that you have to use Javascript and jQuery to render this data there are tons of ready libraries and open source examples on how to do this like:

You can see them and write one yourself like them. Also take a look at more abstracted tool from Telerik .
Hope it helps :)
