Hi everybody,

Why would this code

 if (_dtOrder.Rows.Count == 0) //Add a new order
            {
                _drOrder = _dtOrder.NewOrdersRow();
                _OrderBiz.InsertNewOrder(this._drOrder);
            }

don't change the _dtOrder.Rows.Count ? Should my _OrderBiz.InsertNewOrder method return back the datatable? Or may be I should pass it as a reference and insert.

I'm guessing this is completely wrong implementation

/// <summary>
        /// Insert new order
        /// </summary>
        /// <param name="dr">data row</param>
        /// <returns>ID of new record</returns>
        public int InsertNewOrder(OrdersDataSet.OrdersRow dr)
        {
            int NewOrderID;
            using (OrdersTableAdapter ta = new OrdersTableAdapter())
            {
                dr.OrderPk  = Guid.NewGuid();

                NewOrderID = (int)ta.InsertOrderRecord(dr.OrderPk);
            }
        
            return NewOrderID;
        }

Since I don't know "which" table it now inserted record to and how can I update my reference in the form.

Any ideas of how should I fix it?

Thanks in advance.
