    <p>This is my collection :</p> <pre><code>ObservableCollection&lt;CheckInData&gt; _CheckInCollection = new ObservableCollection&lt;CheckInData&gt;(); public ObservableCollection&lt;CheckInData&gt; CheckInCollection { get { return _CheckInCollection; } } public class CheckInData { public string RoomNumber { get; set; } public string Price { get; set; } public string Currecny { get; set; } public string Discount { get; set; } public string CheckOut { get; set; } public string TotalDay { get; set; } public decimal TotalPrice { get; set; } public int CheckOutYear { get; set; } public int CheckOutMonth { get; set; } public int CheckOutDay { get; set; } public Boolean IncToday { get; set; } public string CheckIn { get; set; } public decimal MoneyRate { get; set; } } </code></pre> <p>I have one class where i save export my collection this way:</p> <pre><code>foreach (CheckInData coll in CheckInCollection) { var roomType = (from d in db.SelectRooms where d.roomnumber == coll.RoomNumber select d.roomtype).SingleOrDefault(); inv._RoomType.Add(roomType.ToString()); inv._RoomNumber.Add(coll.RoomNumber.ToString()); inv._CheckIn.Add(coll.CheckIn); inv._CheckOut.Add(coll.CheckOut); inv._DayNight.Add(coll.TotalDay); inv._RoomPrice.Add(coll.Price); inv._Discount.Add(coll.Discount); } </code></pre> <p>This code works perfectly. I have list view which is binding with this observable collection so my question is how i can insert into <code>inv._RoomType</code>, <code>inv._RoomNumber</code>... only that collection which(rows) are selected in <code>listview</code>. <code>inv._RoomNumber.Add(coll.RoomNumber(listview selected items? ??))</code> Thanks</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
