将子报表值传递给主报表 [英] Passing Subreport Value to Main Report

问题描述

在我的报告中，我通过子报表的总计显示在主报表中，我使用以下公式，

In my Report I am passing the Total of Subreport to display in the Main Report for that I am using the below Formula,

在子报表中，

WhilePrintingRecords;
Shared Numbervar EvTotal:= cdbl({Evaluation_Details.NOOFCOPIESEVALUATED})

Shared NumberVar EvTotal;
EvTotal;

但是当我包括用于在主报表中显示的公式时，它是Dispalying0而不是Total of SubReport

but when I Include the Formula for displaying in the Main Report it is Dispalying "0" instead of Total of SubReport

推荐答案

有几件事情：
在代码中有一些错字。这里你缺少分号在结尾：

A couple of things: You have some typos in your code. Here you were missing the semi-colon at the end:

WhilePrintingRecords;
Shared Numbervar EvTotal:= cdbl({Evaluation_Details.NOOFCOPIESEVALUATED});

在这里你不需要分号：

Shared NumberVar EvTotal;
EvTotal

正如@Raphael指出的，重要的是，在层次结构中比调用变量的主报表中的公式。我也建议有WhileReadingRecords;在这两种方式，你确保他们同时评估。此外，作为一个小调试帮助，把EvTotal在第一个公式的末尾，这样你可以看到的值是/应该是。

And as @Raphael pointed out, it is important that you have the subreport higher in the hierarchy than the formula in the Main Report that calls the variable. I would also suggest to have "WhileReadingRecords;" in both, that way you ensure they evaluate at the same time. Also, as a little debugging help, put "EvTotal" at the end of the first formula, that way you can see what the value is/should be.
