JasperReports动态输入控件 [英] JasperReports dynamic input controls

问题描述

我目前正在尝试使用一些特殊的输入控件行为创建一个JasperReport报告。我的需求是：

• 四个输入控件，其中两个是日期框，其他是单选按钮


• 根据单选按钮的选择，其中一个数据盒应该是可见的


• 所以如果选择了选项1，则显示两个日期框;如果选择了选项2，则只显示一个日期框

我想知道是否有干净的解决方案 - 没有找到任何内容。 / p>

任何指针都会有所帮助。

解决方案

表达时打印与JasperReports Server上的输入控件无关。

没有内置支持隐藏和显示基于不同值的输入控件。用于级联输入控件的基础结构当然可以扩展以实现这一目标......但这不是一件容易的事。

我将采用的路径是自定义.jsp页面显示输入控件。 JasperReports Server Ultimate Guide中有一个名为自定义输入控件表单的部分，可以让您从这条路径开始。

I'm currently trying to create a JasperReport report with some special input control behaviour. My needs are:

• four input controls, two of them are dateboxes, the other ones are radio buttons
• depending on radio button choice, one of the databoxes should be visible or not
• so if option 1 is chosen, show both dateboxes; if option 2 is chosen, show only one datebox

I wonder if there's a "clean" solution - didn't find anything.

Any pointers will be helpful.

解决方案

The Print when expression is not relevant for input controls on JasperReports Server.

There is no built-in support for hiding and showing an input control based on the value of a different one. The infrastructure for cascading input controls can certainly be extended to achieve this... but it would not be trivial.

The path I would take is to customize the .jsp page that displays the input control. There is a section in the JasperReports Server Ultimate Guide called "Customizing the Input Controls Form" which would get you started down this path.
