I want to get a List of items from Model to view, but i am not getting Exact Idea of That Please Help Me I am Adding my all class

Below

    public class DivisionDTO
    {
        public Guid Id { get; set; }
        public string Name { get; set; }
        public List<GroupDTO> Groups { get; set; }
    }
    public class GroupDTO
    {
        public Guid Id { get; set; }
        public string Name { get; set; }
        public List<Team> Teams { get; set; }
    }
 public class Team
    {
        public int ID { get; set; }
        public string TeamName { get; set; }
        public int GroupId { get; set; }
        public int DivisionId { get; set; }

    {
        CreatingLeague.Models.DivisionDTO division = new CreatingLeague.Models.DivisionDTO();
        division.Id = new Guid();
        division.Name = "Div";
        division.Groups = new List<CreatingLeague.Models.GroupDTO>();

        CreatingLeague.Models.Team team = new Models.Team();
        team.TeamName = "TeamA";
        division.Groups.Add(new CreatingLeague.Models.GroupDTO() { Id = new Guid(), Name = "G1", Teams = new List<Team>() { team } });
        return View(division);
    }

I want to make a edit page can any one give me idea of that

You can loop over the individual groups in the razor View.

@model DivisionDTO

@for (var i = 0; i < Model.Groups.Count(); i++) {

    @Html.EditorFor(m => m.Groups[i].Name) 

    @for (var j = 0; j < Model.Groups[i].Teams.Count(); j++) {
         @Html.EditorFor(m => m.Groups[i].Teams[j].TeamName) 
    }
}

Do not use foreach, because the indices i, j are needed by the MVC modelbinder.

Your POST action can take the DivisonDto as model, the child collections will have data.

[HttpPost]
public ActionResult Save(DivisonDto model) {
    var firstGroupName = model.Groups[0].Name;
    // ...
}
