如何防止JasperReports TextField中的重复数据 [英] How to prevent repeating data in JasperReports TextField

问题描述

我正在使用 JasperReports 并且在下一页继续使用textField数据时出现问题。

我有3个textField详细信息。

Band splitType =Stretch。

每个textfiled都有边框，isPrintWhenDetailOverflows param设置为true。

当textfield中的数据不适合页面时，它继续下一步。所以我需要打印相同波段的其他文本（因为我需要打印每个文本字段的边框）

但isPrintWhenDetailOverflows =true也导致在第二页上的其他文本字段中重复数据，尽管它们的内容适合第一页。

I am using JasperReports and have some problem with textField data continue on next page.
I have 3 textField in detail band.
Band splitType="Stretch".
Every textfiled has borders and isPrintWhenDetailOverflows param set "true".
When data in textfield does not fit on page it continues on next. So i need to print other textfileds of same band (because i need to print borders of every textfield)
But isPrintWhenDetailOverflows="true also leads to repeating data in other textfields on second page though their contents fits on first page.

推荐答案

jasper报告文档说：

The jasper report documentation says:

isPrintWhenDetailOverflows()
If this is set to true, the element will be reprinted on the next page if the band does not fit in the current page.

所以我认为这可能是一个问题。删除 isPrintWhenDetailOverflows =true。两件事 isStretchWithOverflow =true 和 在这种情况下，stretchType =RelativeToTallestObject 正在为我工​​作。所以你的 textField 将如下：

So I think it might be a problem. Remove isPrintWhenDetailOverflows="true". The two things isStretchWithOverflow="true" and stretchType="RelativeToTallestObject" are working for me in this case. So your textField will be like:

<textField isStretchWithOverflow="true" isBlankWhenNull="true">
   <reportElement style="cell" stretchType="RelativeToTallestObject" x="266" y="0" width="266" height="15"/>
   <textElement textAlignment="Left" verticalAlignment="Middle">
     <font fontName="Arial" size="9" isBold="false" pdfEncoding="Cp1251" isPdfEmbedded="true"/>
     <paragraph leftIndent="2"/>
   </textElement>
   <textFieldExpression><![CDATA[$F{structure}]]></textFieldExpression>
</textField>
