I've written a custom tab control (FooTabControl) which hosts specific tab page controls (FooTabPage instances). The FooTabPages know to place themselves into a dedicated area within the FooTabControl.
我编写了一个自定义选项卡控件(FooTabControl),它托管特定的选项卡页面控件(FooTabPage实例)。 FooTabPages知道将自己置于FooTabControl中的专用区域。
Now I wish to have the FooTabControl also host a System.Windows.Forms.Panel child control (in another dedicated area of the FooTabControl). I want the user to be able to place his controls into this Panel, but disallow him from removing the Panel control itself (while still being able to add and remove FooTabPages as he sees fit).
现在我希望FooTabControl还托管一个System.Windows.Forms.Panel子控件(在FooTabControl的另一个专用区域中)。我希望用户能够将他的控件放入这个Panel,但是不允许他移除Panel控件本身(同时仍然能够按照他认为合适的方式添加和删除FooTabPages)。
What would be the proper way to implement this?
实现这个的正确方法是什么?

You need to override CreateControlsInstance (in the custom control) and return you own implementation of ControlCollection.
In your implementation your will override Remove to disallow removing the Panel.
您需要覆盖CreateControlsInstance(在自定义控件中)并返回您自己的ControlCollection实现。在您的实现中,您将覆盖删除以禁止删除Panel。
