Question

Can anyone tell me why this doesn’t set the value on the ListItems to ID? Value and Text both come out as DISPLAY_NAME

  lstSelected.DataSource = entities.User
     .Where(x => SelectedItems.Contains(x.ID))
     .Select(x => new ListItem { Text = x.DISPLAY_NAME, Value = x.ID })
     .ToList<ListItem>();

  lstSelected.DataBind();

Answer 1

Try setting DisplayMember and ValueMember properties (or DataTextField and DataValueField if you are using asp.net)

lstSelected.DisplayMember = "DISPLAY_NAME";
lstSelected.ValueMember = "ID";
lstSelected.DataSource = entities.User
     .Where(x => SelectedItems.Contains(x.ID))
     .ToList();
lstSelected.DataBind();
