如何在C#中将相同的控件添加到多面板中? [英] How to add the same control into multi panel in C#?

问题描述

我有一个名为button1的按钮，两个面板分别为:panelA和panelB(默认情况下，visible为false)和以下代码(WinForms):

I have a button called button1 and two panels called: panelA and panelB (visible is false by default) and the following code (WinForms):

panelA.Controls.Add(button1);
panelB.Controls.Add(button1);
panelB.Visible = true; // I see the button1
panelA.Visible = true; // I don't (ofcoz panelB.Visible is still false)
MessageBox.Show(panelA.Controls.Contains(button1).ToString); //False, why?

我不知道为什么?也许这对您来说是个愚蠢的问题，但我是新手，所以我对这个问题一无所知?你能帮助我吗?谢谢！

I don't know why? Maybe it's a stupid question for you but I'm a newbie so I don't really have any idea about this problem? Can you help me? Thanks!

推荐答案

对象button1只能具有一个可视父对象.因此，您不应将其添加到2个不同的父母中.

The object button1 can have only one visual parent. Therefore you shouldn't add it to 2 different parents.

因此，您需要有2个按钮对象.

So, you need to have 2 button objects.
