在代码后面检查以查看是否已将控件设置为显示:无? [英] Code-behind check to see if a control has been set to display: none?

问题描述

我目前有一个控件，正在使用 dropdown.hide(); .

I currently have a control that is being hidden on my server side using dropdown.hide();.

hide()是我创建的用于隐藏方法的服务器端方法，例如

hide() is a server-side method I created to hide my methods, e.g.

control.Style["display"] = "none";

如何在服务器端知道我的控件是否隐藏?

How can I tell, on the server-side, if my control is hidden or not?

推荐答案

我猜你不是在说:

if (control.Style["display"] == "none") { .... }

您希望在回发后知道吗?如果真是这样，那么除非您使用JavaScript将事实隐藏在隐藏的输入或类似的内容中，否则您将无法做到这一点.

And that you want to know after a postback? If that's the case, then you can't do it, unless you store the fact it's hidden in a hidden input or something like that, using JavaScript.
