将面板复制到在运行时创建的另一个面板

问题描述

嘿，

我试图将一个面板复制到在运行时创建的另一个面板，但是旧面板不断消失，您能告诉我什么地方出问题吗?

我的代码:

Hey,

I'' trying to copy one panel into another panel which is created at run time but the old panel keeps disappearing , can you tell me what''s wrong ?

my code :

Friend withevent NewPanel As New Panel
Me.Controls.Add(NewPanel)
NewPanel = Panel1
NewPanel.Top=Panel1.Top + Panel1.Height 

推荐答案

NewPanel.Left = Panel1.Left
NewPanel.Top = Panel1.Top

添加与配置旧面板一样需要配置新面板的所有属性.

然后，您需要对面板中的所有控件执行类似的操作.

实话实说，这是很多艰苦的工作.我将创建一个自定义控件，其中包含一个面板以及该面板中包含的所有控件.然后，您只需要创建自定义控件的新实例.

以下是开发自定义控件的介绍.

Adding all the properties you need to configure the new panel as the old one was.

You then need to do a similar thing for the all the controls within the panel.

Truth be told, that''s a lot of hard work. I''d create a custom control which contains a Panel and all the controls contained within the Panel. Then you need only create a new instance of your custom control.

The following is an introduction to developing custom controls.
