Crystal Reports - 更改每个详细信息视图的参数值
我正在处理一个 Crystal Reports 文档,我需要更改将从代码隐藏生成的参数。我已经知道如何通过代码设置参数的值,但是我需要它在详细信息视图中动态工作。
因为详细信息视图可能会出现多次,所以我想知道是否可以在每次详细信息视图运行时以编程方式为参数设置不同的值?我知道最好获取数据集中的值,这就是我已经在做的事情,但是对于这个值,它需要通过参数输入,因为它不存在于我们的 sql 数据库中。
任何帮助将不胜感激。
I am working on a Crystal Reports document which I require changing a parameter that will be produced from the code-behind. I already know how to set the parameter's value through the code, however I need it to work dynamically in the details view.
Because the details view can occur many times, I would like to know if it is possible to programmatically set a different value to the parameter every time the details view runs? I know it would be better to get the value from a dataset, which is what I am already doing, but for this value it needs to be entered through a parameter simply because it does not exist in our sql databases.
Any help would be greatly appreciated.
