RDLC Winfoms C#可见性属性 [英] RDLC winfoms c# visibility property

问题描述

你好，
表达式不适用于Winfoms中的rdlc

= iif(First(Fields！xyz.Value，"dataset")> 0，true，false)
或
= iif(First(Fields！xyz.Value)> 0，true，false)

我的要求是根据上述表达式设置矩形的可见性.
实际上，我想检查数据集是否为空，然后不显示矩形.
矩形包含绑定到数据集中字段的文本框.
请帮助我.

推荐答案

尝试:

=iif(CountRows("Dataset1") >0, true, false)

可见性表达式.

参考: MSDN:CountRows函数(报告服务) [ ^ ]

for the visibility expression.

Refer: MSDN: CountRows Function (Reporting Services)[^]
