推荐答案

这里有一个完整的WinForms可折叠UserControl示例（源文件和.exe文件）：[ ^ ]。



此项目是针对.NET 3.0编译的。



它演示了UserControl自身调整大小，因为底部的Panel在运行时可见或被用户隐藏。它演示了UserControl Panel可见性的控制，包括它所在的Form和来自 in UserControl的内容。



它还演示了考虑到需要在更改时调整UserControl，以便考虑UserControl的填充因子，并且UserControl保持一致的虚拟边框。



如果我对你的目标的假设（在我对你的OP的评论中表达）是正确的，创建一个可折叠的UserControl（或Panel），其中一个ContainerControl可见或隐藏，UserControl / Panel调整自身以适应当前内容...是我经常做的事情。



imho，简单......一旦你完成了一次:)我一直想为CodeProject写这个，所以，这就是初稿。



不幸的是，WinForms中的UserControls和ContainerControls（如Panels）的AutoSize属性存在实际问题：一旦你有控件位于这些容器中Docked，你将在运行时遇到问题。如果您认为可以使用AutoSize，请忘记它。



唯一的选择我知道o f是本例中演示的类型。< br $> b $ b

There's a complete working WinForms example of a Collapsible UserControl (source and .exe files) here: [^].

This Project is compiled against .NET 3.0.

It demonstrates the UserControl resizing itself as a Panel at the bottom is made visible, or hidden by the user at run-time. It demonstrates control of the UserControl Panel visibility both from the Form it is sited in, and from within the UserControl.

It also demonstrates taking into account the need to adjust the UserControl when it's changed so that the Padding factor of the UserControl is taken into account, and the UserControl maintains a consistent "virtual border."

If my assumptions about your goal (expressed in my comment to your OP) are correct, creating a collapsible UserControl (or Panel), where one ContainerControl is made visible, or is hidden, and the UserControl/Panel resizes itself to fit the current contents ... is something I have done frequently.

imho, easy ... once you've done it once :) I have been meaning to write this up for CodeProject, so, this is kind of the "first draft."

Unfortunately, there are real problems with the AutoSize Property of both UserControls and ContainerControls, like Panels, in WinForms: once you have Controls sited within these containers that are Docked, you are going to have problems at run-time. If you thought you could use AutoSize, forget it.

The only alternative I know of is the kind demonstrated in this example.

Happy Holidays !

什么可能使它成为问题？

And what could make it a problem?

Panel Footer = //...
//...
Footer.Visible = false;
