How to bind List to my repeater in asp.net?

public class Post
{
   public int id { get; set; }
   public string title { get; set; }
   public string body { get; set; }
   public List<Comments> comments { get; set; }
}

public class Comments{
   public int id { get; set; }
   public string author { get; set; }
   public string text { get; set; }
}

My data layer returns 开发者_Python百科the data I need:
List<Posts> post = (List<Post>)myDataLayer.GetPostAsList();

post has just one post in it even though it is a List.

I have 2 repeater controls. The first is the posts repeater. The second is the comments repeater which is outside the Posts repeater.

How can I pull the List<Comments> out of Posts and bind to the Comments repeater?

The simplest way:

<asp:Repeater runat="server" ID="rptPosts">
    <ItemTemplate>
        <!-- markup for posts here-->
    </ItemTemplate>
</asp:Repeater>

<asp:Repeater runat="server" ID="rptComments">
    <ItemTemplate>
        <!-- markup for comments here-->
    </ItemTemplate>
</asp:Repeater>

The thing left is to bind data:

protected override void DataBind()
{
    var posts = myDataLayer.GetPostAsList();
    // if there is at leat one post
    if (posts.Any())
    {
        rptPosts.DataSource = posts;
        rptPosts.DataBind();

        // you mentioned that there should be only one post in the list
        var comments = posts.First().comments;
        rptComments.DataSource = comments;
        rptComments.DataBind();
    }
}
