creation of view with dynamic Model in asp.net mvc

Question

I am new Asp.Net Mvc . I am doing a sample application for Blogging . I tried to create Partial view for Archives for categorizing Post according to date .

Month/Year(count)
  Post 1
  Post 2
Month/Year(count)
  Post 1
  Post 2

In Controller

[ChildActionOnly]
    public ActionResult Archives()
    {
        var post = from p in db.Posts
                   group p by new { Month =p.Date.Month, Year = p.Date.Year } into d
                   select new { Month = d.Key.Month , Year = d.Key.Year , count = d.Key.Count(), PostList = d};

        return PartialView(post);
    }

Please help me write View for this Action with this Month, Year , Count and collection of Post .

Answer 1

You may be struggling because you are passing an anonymous type into your View. I would create a ViewModel to represent your type;

public class Archive
{
  public string Month { get; set; }
  public string Year { get; set; }
  public int Count { get; set; }
  public ICollection<Post> Posts { get; set; }
}

and then change your action to use the type;

[ChildActionOnly]
public ActionResult Archives()
{
  var post = from p in db.Posts
    group p by new { Month =p.Date.Month, Year = p.Date.Year } into d
    select new Archive { Month = d.Key.Month , Year = d.Key.Year, Count = d.Key.Count(),
      PostList = d };

    return PartialView(post);
}

and then you can strongly type your view to the Archive class;

@model IEnumerable<Archive>

@foreach (Archive archive in Model)
{
  <h2>
    @archive.Month / @archive.Year
  </h2>
}

Let me know if I can be of further assistance.
