如何更改ReportViewer中文本框的可见性？

I have a report viewer, and in a given circumstance, I want to change the visibility of a textbox inside the report viewer. I already changed the name of the textbox, but I cant access the textbox from outside.

我有一个报表查看器，在给定的情况下，我想更改报表查看器中文本框的可见性。我已经更改了文本框的名称，但我无法从外部访问文本框。

I tried this (which not compile):

我试过这个（不编译）：

myReportViewer.txbPI.Visible = false

What should I do please?

我该怎么办？

Thanks.

谢谢。

You could add an expression for the Hidden property of the textbox and hide it based on the value of a data item (if you bind the report to a data source) or report parameter.

您可以为文本框的隐藏属性添加表达式，并根据数据项的值（如果将报表绑定到数据源）或报表参数隐藏它。
