取消UpdateTotalAmount方法及改变编程方式

C# Code:


private void OnCellValueChanged(object sender, CellValueChangedEventArgs e)
{
   //只要单价和数量栏位改动重新计算金额
   if ((e.Column == colD_Price) || (e.Column == colD_Qty))
   {
      this.UpdateDetailAmount();//重新计算金额
   }
}

/// <summary>
/// 当用户修改单价/数量列, 自动计算采购金额
/// </summary>
private void UpdateDetailAmount()
{
   decimal price = ConvertEx.ToDecimal(gvDetail.GetDataRow(gvDetail.FocusedRowHandle)[tb_SOs.Price]);//单价
   decimal quantity = ConvertEx.ToDecimal(gvDetail.GetDataRow(gvDetail.FocusedRowHandle)[tb_SOs.Qty]);//数量
   decimal amt = Math.Round(price * quantity, 2, MidpointRounding.ToEven);//金额=数量*单价
   
   //计算本产品的采购金额
   gvDetail.SetFocusedRowCellValue(colD_Amount, amt);
   
   gvDetail.UpdateCurrentRow();//更新当前资料行
   gvDetail.UpdateTotalSummary();//更新合计
   
   //更新主表的合计金额
   decimal totalAmt = ConvertEx.ToDecimal(colD_Amount.SummaryItem.SummaryValue);
   this.SetEditorBindingValue(txtAmount, totalAmt, true);
}
