activereports - 如何在活动报告的最后一页获取列的总和

Question

我有一个活动报告，其中包含名为存款和取款的两列。我想在活动报告的最后一页获得两列的总和。我在 ReportStart 事件中做了一些代码

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;

我也已经在报告页脚中做到了，但仍然没有得到存款和取款金额的总和。我怎样才能得到列的总和？

Answer 1

SummaryRunning设置基本上定义了何时将累计总数重置为零。对于报表级别的总计值，您不希望重置该值 - 您希望它在整个报表中继续累积。所以你不需要这里的SummaryGroupandSummaryRunning属性。因此，根据SummaryType 属性文档中的示例，您可以设置 SummaryGroup 和 SummaryRunning 属性，如下所示：

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