Following is an example of creating a transaction when require to save on many tables at once. I used Microsoft Enterprise Libraries. I assume one to many relation.

Dim _Connection As DbConnection = Nothing
Dim _Transaction As DbTransaction = Nothing

Try

         Dim _DB As Database = DatabaseFactory.CreateDatabase("YourConnectionStringNameInConfigFile")
         _Connection = _DB.CreateConnection
         _Connection.Open()
         _Transaction = _Connection.BeginTransaction()

        //Inserting Master table record, You can set parameters here
    .Insert(_DB, _Transaction)

                              For i As Integer = 0 To NoOfItemsInGrid

                     //Inserting Transaction Records, You can set parameters here
          .Insert(_DB, _Transaction)

                             Next

               _Transaction.Commit()

               Catch ex As Exception

_Transaction.Rollback()

Finally

If _Connection.State = ConnectionState.Open Then
_Connection.Close()

End If

End Try
