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 break point, recognize items list has items. cant in page.

set datasource listview , try 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();         }
