Thanks a lot, this is going to work splendid, but now I'm getting this error

 _drItem.Price = (decimal)this.txtPrice.Text; // doesn't compile
        _drItem.Qty = (int)this.txtQty.Text; //doesn't compile

Error	4	Cannot convert type 'string' to 'int'	W:\sdc\SDCBarcodeScannerProject\SDCBarcodeScannerProject\SDCBarcodeScannerDeviceClient\OrdersEntryForm.cs	568	23	SDCBarcodeScannerDeviceClient
