如何在活動報告的最後一頁獲得列的總和

Question

我有一個活動報告，其中有兩列名爲Deposit and Withdrawal。我想要獲得活動報告最後一頁的兩列總和。我在ReportStart事件做了一些代碼

var fldDepositTotal = ar.Sections["gfDetail"].Controls["fldDepositTotal"] as DataDynamics.ActiveReports.TextBox; 
var fldWithdrawalTotal = ar.Sections["gfDetail"].Controls["fldWithdrawalTotal"] as DataDynamics.ActiveReports.TextBox; 

      fldDepositTotal.DataField = "AmountD"; // Your datafield value 
      fldDepositTotal.SummaryFunc = SummaryFunc.Sum; 
      fldDepositTotal.SummaryGroup = "ghDetail"; 
      fldDepositTotal.SummaryRunning = SummaryRunning.Group; 
      fldDepositTotal.SummaryType = SummaryType.GrandTotal; 


      fldWithdrawalTotal.DataField = "AmountW"; // Your datafield value 
      fldWithdrawalTotal.SummaryFunc = SummaryFunc.Sum; 
      fldWithdrawalTotal.SummaryGroup = "ghDetail"; 
      fldWithdrawalTotal.SummaryRunning = SummaryRunning.Group; 
      fldWithdrawalTotal.SummaryType = SummaryType.GrandTotal; 

我必須讓它在報告頁腳也不過的存款和取款金額仍然沒有得到總和。我怎樣才能得到列的總和？

SummaryRunning setting基本上定義何時將重新設置累計總數爲零。如果報告級的總價值不高，您不希望重置價值 - 您希望它在整個報告中繼續累積。所以你不需要這裏的SummaryGroup和SummaryRunning屬性。因此，根據the SummaryType property's documentation中的示例，您可以按如下方式設置SummaryGroup和SummaryRunning屬性：

fldDepositTotal.DataField = "AmountD"; 
fldDepositTotal.SummaryFunc = SummaryFunc.Sum; 
fldDepositTotal.SummaryGroup = null; 
fldDepositTotal.SummaryRunning = SummaryRunning.None; 
fldDepositTotal.SummaryType = SummaryType.GrandTotal;
