        </asp:ListView>

C#

     public class Place
            {
                public string RoomType { get; set; }

                public string Description { get; set; }
            }

            List<Place> items = new List<Place>();
                        items.Add(new Place() { RoomType = "RoomType1", Description= "RoomType Description"});
                        items.Add(new Place() { RoomType = "RoomType2", Description = "RoomType Description" });
                        items.Add(new Place() { RoomType = "RoomType3", Description = "RoomType Description" });

  ListView1.DataSource = items;

While checking with Break point, i recognize the items list has the items. but i cant get in my page.

Answer 1

Set the datasource for listview and try the below code

protected void Page_Load(object sender, EventArgs e)
        {
            List<Place> items = new List<Place>();
            items.Add(new Place() { RoomType = "RoomType1", Description = "RoomType Description" });
            items.Add(new Place() { RoomType = "RoomType2", Description = "RoomType Description" });
            items.Add(new Place() { RoomType = "RoomType3", Description = "RoomType Description" });
            this.ListView1.DataSource = items;
            this.ListView1.DataBind();
        }

Answer 2

I did not see any error. Could you please check your list added or not by writing them to console ?

Console.WriteLine();
        foreach (Place item in items)
        {
            Console.WriteLine(item);
        }

Please add an foreach function to see.
