You need to do following. DataRelation dr = new DataRelation("BookBookName", ds.Tables["MBook"].Columns["BookId"], ds.Tables["Book"].Columns["BookId"]); DataRelation dr1 = new DataRelation("BookAuthorName", ds.Tables["MBook"].Columns["AuthorId"], ds.Tables["AName"].Columns["AuthorId"]); and so on. So you have finally four datarelation object. Then add all relation object to dataset, like.. ds.Relations.Add(dr); ds.Relations.Add(dr1); ds.Relations.Add(dr2); You can do navigation as follows foreach (DataRow MBookRow in customerOrders.Tables["NBook"].Rows) { Console.WriteLine(MBookRow["MBookId"].ToString()); foreach (DataRow BNameRow in MBookRow.GetChildRows(dr1)) { Console.WriteLine(BNameRow\["BookId"\].ToString() + " " + BNameRow\["BookName"\].ToString()); } } Refer this[^] link for DataSet Vs NHibernate.

DataAdapters are evil and should be avoided. If you want to insert some data, just insert it, it's not difficult and you'll be better off.

You can place your own contol in the dropdownlist of a combobox, see here: http://www.codeproject.com/KB/combobox/CustomComboBox.aspx

Thanks I GOT :thumbsup: :)

You will need to handle either key down, key up or key press events. Make sure to check for modifier keys. You will also need to handle pasting too.
