如何在展开和折叠时更改文本框的值 [英] how to change value of a textbox on expand and collapse

问题描述

大家好，

我创建了一个简单的报告.在此报告中，我有一个标题，所有详细信息都在其下方.现在，所有详细项目的可见性设置为ToggleItem并设置为标题文本框.这意味着当您单击标题时，它将切换详细控件的可见性.一切都好.

问题是当有人展开或折叠它以显示全部或全部隐藏时，我只想更改标题文本.这样的事情.

有帮助吗?

在此先感谢您.

HI all,

I have created a simple report. In this report I have a header and all the details are below that. Now All the detailed items'' visibility is set to ToggleItem and set to the header textbox. That means when you click on header it will toggle the visibility of detailed controls. Everything is fine.

Problem is I just want to change the header text when someone Expand or Collapse it to show all or hide all. Something like that.

Any help??

Thanks in advance.
