Re: C# navigation buton kodları

C#
var rows = DS.Tables[0].AsEnumerable();

                DataRow firstRow = rows.First ();
                DataRow lastRow = rows.Last ();
 
              DataRow current = rows.ElementAt( 4 );
              DataRow next = rows.ElementAt( 5 );
              DataRow previous = rows.ElementAt( 3 );
 
              foreach (var row in rows)
              {
                    //...
              }

BindingSource filan yok mu. Onun current'ina baksan.
